Face detection and analysis is an important area in computer vision. Furthermore, face detection has been an active research field in the recent years following the advancement in digital image processing. The visualisation of visual entities or sub-pattern composition may become complex to visualise due to the high frequency of noise and light effect during examination. This study focuses on evaluating the ability of Haar classifier in detecting faces from three paired Min-Max values used on histogram stretching. Min-Max histogram stretching was the selected method for implementation given that it appears to be the appropriate technique from the observation carried out. Experimental results show that, 60-240 MinMax values, Haar classifier can accurately detect faces compared to the two values.

Does electro-sensing fish use the first order polarization tensor for object characterization? object discrimination test

Taufiq K.A. Khairuddin, Lionheart W

Sains Malaysiana, 2014;43:1775-1779.

This paper extends the previous works to further explore the role of the first order polarization tensor in electro-sensing by the weakly electric fish specifically for object discrimination and characterization. The first order polarization tensor for few objects used in the considered experiment are calculated and discussed to identify whether there are other evidences to suggest that a weakly electric fish able to recognize the tensor when choosing or rejecting an object. Our findings in this study suggest that all fish during most of the experiments face difficulties to discriminate two objects when their first order polarization tensors are almost similar depending on the types of training given to them.

This study is aimed at determining whether there exists a correlation between the relative dimensions of the nose and the face. Through this study, we hoped to give a normal range for the different races in Malaysia. We randomly chose 100 Malay, 50 Chinese and 50 Indian subjects. We chose equal numbers of male and female subjects, mainly in their 20's and 30's. There is a correlation between the length of the nose and the face among Malays, with 78% of the subjects measured having a nose:face ratio of less than 0.27. There is also a correlation between the breadth of the nose and the face among Malays, with 670/0 of the subjects having a ratio of less than 0.28. Similar correlations were found with Chinese and Indian subjects. The length and breadth of the nose in relation to the face is greater in males than in females. Further research is required before conclusive evidence is found for the existence or non existence of a correlation between the length and breadth of the nose and face in the different races in Malaysia. KEYWORDS: Correlation, length, breadth, nose, nace, different races.

Fulltext Support vector machine based on adaptive acceleration particle swarm optimization

Abdulameer MH, Sheikh Abdullah SN, Othman ZA

ScientificWorldJournal, 2014;2014:835607.

PMID: 24790584 DOI: 10.1155/2014/835607

Existing face recognition methods utilize particle swarm optimizer (PSO) and opposition based particle swarm optimizer (OPSO) to optimize the parameters of SVM. However, the utilization of random values in the velocity calculation decreases the performance of these techniques; that is, during the velocity computation, we normally use random values for the acceleration coefficients and this creates randomness in the solution. To address this problem, an adaptive acceleration particle swarm optimization (AAPSO) technique is proposed. To evaluate our proposed method, we employ both face and iris recognition based on AAPSO with SVM (AAPSO-SVM). In the face and iris recognition systems, performance is evaluated using two human face databases, YALE and CASIA, and the UBiris dataset. In this method, we initially perform feature extraction and then recognition on the extracted features. In the recognition process, the extracted features are used for SVM training and testing. During the training and testing, the SVM parameters are optimized with the AAPSO technique, and in AAPSO, the acceleration coefficients are computed using the particle fitness values. The parameters in SVM, which are optimized by AAPSO, perform efficiently for both face and iris recognition. A comparative analysis between our proposed AAPSO-SVM and the PSO-SVM technique is presented.

The post-mortem resilience of facial creases and the possibility for use in identification of the dead

Hadi H, Wilkinson CM

Forensic Sci Int, 2014 Apr;237:149.e1-149.e7.

PMID: 24613011 DOI: 10.1016/j.forsciint.2013.12.014

The post-mortem resilience of facial creases was studied using donated bodies in order to establish the efficacy of crease analysis for identification of the dead. Creases were studied on normal (pre-embalmed) and bloated (embalmed) cadavers at the Centre for Anatomy and Human Identification (CAHID) to establish whether facial bloating would affect facial crease visibility. Embalming was chosen to simulate the effects produced by post-mortem bloating. The results suggested that creases are resilient and changes were only detected for creases located on the periphery of the face, particularly at areas where the skin is thick, such as at the cheeks. Two new creases not previously classified were identified; these creases were called the vertical superciliary arch line and the lateral nose crease. This research suggests that facial creases may be resilient enough after death to be utilised for human identification.

Ensuring uniformity in the nomenclature standardization of facial creases is important to enable the scholarly community to follow and debate the advancements in research. This review highlights the prevailing disparity in the nomenclature that refers to the same facial crease by researchers and laypeople, and suggests uniform names for the facial creases based on available literature. The previous and current trends in facial crease classification are also discussed. The nomenclature of the facial creases considered for this review include the following: the nasolabial fold, corner of the mouth lines, upper and lower lip creases around the mouth region, the mandibular folds, the bifid nose, the transverse nasal line, the vertical glabellar line, chin crease, the mental crease, four type of creases around the eyes, forehead creases, and periauricular creases. A figure illustrating the above facial creases is included as reference. It is hoped that the proposed standardization of nomenclature would ensure a more scientific referencing of facial creases enabling more effective scientific interaction among the scholarly community as well as the laypeople interested in the research and application of facial creases.

Fulltext Automated detection of pain levels using deep feature extraction from shutter blinds-based dynamic-sized horizontal patches with facial images

Barua PD, Baygin N, Dogan S, Baygin M, Arunkumar N, Fujita H, et al.

Sci Rep, 2022 Oct 14;12(1):17297.

PMID: 36241674 DOI: 10.1038/s41598-022-21380-4

Pain intensity classification using facial images is a challenging problem in computer vision research. This work proposed a patch and transfer learning-based model to classify various pain intensities using facial images. The input facial images were segmented into dynamic-sized horizontal patches or "shutter blinds". A lightweight deep network DarkNet19 pre-trained on ImageNet1K was used to generate deep features from the shutter blinds and the undivided resized segmented input facial image. The most discriminative features were selected from these deep features using iterative neighborhood component analysis, which were then fed to a standard shallow fine k-nearest neighbor classifier for classification using tenfold cross-validation. The proposed shutter blinds-based model was trained and tested on datasets derived from two public databases-University of Northern British Columbia-McMaster Shoulder Pain Expression Archive Database and Denver Intensity of Spontaneous Facial Action Database-which both comprised four pain intensity classes that had been labeled by human experts using validated facial action coding system methodology. Our shutter blinds-based classification model attained more than 95% overall accuracy rates on both datasets. The excellent performance suggests that the automated pain intensity classification model can be deployed to assist doctors in the non-verbal detection of pain using facial images in various situations (e.g., non-communicative patients or during surgery). This system can facilitate timely detection and management of pain.

An unexpected presentation of very severe hypertriglyceridemia in a boy with Coffin-Lowry syndrome: a case report

Tan SL, Ahmad Narihan MGB, Koa AJ

BMC Pediatr, 2023 Oct 28;23(1):541.

PMID: 37898736 DOI: 10.1186/s12887-023-04376-5

BACKGROUND: Coffin-Lowry syndrome (CLS) is a rare X-linked condition with intellectual disability, growth retardation, characteristic facies and skeletal anomalies. To date, hypertriglyceridemia has not been reported in literature to be associated with CLS.

CASE PRESENTATION: Herein, we report a case of very severe hypertriglyceridemia 32 mmol/L (2834 mg/dL) detected incidentally at three months old in an otherwise well boy born late preterm with intrauterine growth restriction, when he presented with lipaemic plasma. He was later diagnosed with CLS. No pathogenic mutations were found for hypertriglyceridemia, and no secondary causes could explain his very severe hypertriglyceridemia.

CONCLUSIONS: The very severe hypertriglyceridemia in this case may appear to be a serious presentation of an unrecognised clinical feature of CLS, further expanding its phenotype.

Fulltext Investigation of age-related facial variation among Angelman syndrome patients

Agbolade O, Nazri A, Yaakob R, Ghani AA, Cheah YK

Sci Rep, 2021 10 21;11(1):20767.

PMID: 34675349 DOI: 10.1038/s41598-021-99944-z

Angelman syndrome (AS) is one of the common genetic disorders that could emerge either from a 15q11-q13 deletion or paternal uniparental disomy (UPD) or imprinting or UBE3A mutations. AS comes with various behavioral and phenotypic variability, but the acquisition of subjects for experiment and automating the landmarking process to characterize facial morphology for Angelman syndrome variation investigation are common challenges. By automatically detecting and annotating subject faces, we collected 83 landmarks and 10 anthropometric linear distances were measured from 17 selected anatomical landmarks to account for shape variability. Statistical analyses were performed on the extracted data to investigate facial variation in each age group. There is a correspondence in the results achieved by relative warp (RW) of the principal component (PC) and the thin-plate spline (TPS) interpolation. The group is highly discriminated and the pattern of shape variability is higher in children than other groups when judged by the anthropometric measurement and principal component.

Majeed A, Mt Piah AR, Gobithaasan RU, Yahya ZR

PLoS One, 2015;10(4):e0122854.

PMID: 25880632 DOI: 10.1371/journal.pone.0122854

This paper proposes the reconstruction of craniofacial fracture using rational cubic Ball curve. The idea of choosing Ball curve is based on its robustness of computing efficiency over Bezier curve. The main steps are conversion of Digital Imaging and Communications in Medicine (Dicom) images to binary images, boundary extraction and corner point detection, Ball curve fitting with genetic algorithm and final solution conversion to Dicom format. The last section illustrates a real case of craniofacial reconstruction using the proposed method which clearly indicates the applicability of this method. A Graphical User Interface (GUI) has also been developed for practical application.

Do they 'look' different(ly)? Dynamic face recognition in Malaysians: Chinese, Malays and Indians compared

Wong HK, Keeble DRT, Stephen ID

Br J Psychol, 2023 May;114 Suppl 1:134-149.

PMID: 36647242 DOI: 10.1111/bjop.12629

Previous cross-cultural eye-tracking studies examining face recognition discovered differences in the eye movement strategies that observers employ when perceiving faces. However, it is unclear (1) the degree to which this effect is fundamentally related to culture and (2) to what extent facial physiognomy can account for the differences in looking strategies when scanning own- and other-race faces. In the current study, Malay, Chinese and Indian young adults who live in the same multiracial country performed a modified yes/no recognition task. Participants' recognition accuracy and eye movements were recorded while viewing muted face videos of own- and other-race individuals. Behavioural results revealed a clear own-race advantage in recognition memory, and eye-tracking results showed that the three ethnic race groups adopted dissimilar fixation patterns when perceiving faces. Chinese participants preferentially attended more to the eyes than Indian participants did, while Indian participants made more and longer fixations on the nose than Malay participants did. In addition, we detected statistically significant, though subtle, differences in fixation patterns between the faces of the three races. These findings suggest that the racial differences in face-scanning patterns may be attributed both to culture and to variations in facial physiognomy between races.

Combined genioplasty, chondrolaryngoplasty, and glottoplasty: A novel scarless procedure in facial feminization surgery

Labarthe P, Beaudoin PL, Wong E, Garrel R, de Boutray M, Damecourt A

J Stomatol Oral Maxillofac Surg, 2023 Dec;124(6S2):101575.

Facial feminization is a long process with multiple surgical steps that is known to improve quality of life in transgender patients. Visible scars are a frequent complaint by this community as it adds to the stigmatization in this population. Combined procedures have been shown to be effective, by reducing the number of hospitalizations and the total length of recovery periods. In this context, we propose a novel scarless procedure combining a chondrolaryngoplasty, a glottoplasty, and a genioplasty using solely a transoral approach. First, we perform a glottoplasty according to the technique described by Wendler et al. and then a contraction genioplasty. Finally, the thyroid cartilage is approached by a subplatysmal dissection, between the mandibular osteotomy fragments. For now, 15 patients have benefited from this procedure in our department. Preliminary results demonstrate that this is an easy and safe procedure with good esthetic results and good patient satisfaction.
