Face and Gender Classification in Crowd Video

چکیده
Research in face and gender recognition under constrained environment has achieved an acceptable level of performance. There have been advancements in face and gender recognition in unconstrained environment, however, there is significant scope of improvement in surveillance domain. Face and gender recognition in such a setting poses a set of challenges including unreliable face detection, multiple subjects performing different actions, low resolution, and sensor interoperability. Existing video face databases contain one subject in a video sequence. However, real world video sequences are more challenging and generally contain more than one person in a video. This thesis provide the annotated crowd video face database with more than 200 videos pertaining to more than 100 individuals, along with face landmark information and gender annotation to encourage research in this important problem. We provide two distinct use-case scenarios, define their experimental protocols, and report baseline verification results existing on two face recognition systems, OpenBR and FaceVACS. Gender classification is also performed on this database and the results are reported using OpenBR along with a combination of different feature extractors with SVM classification. The results show that both the baseline results do not yield more than 0.16 genuine accept rate at 0.01 false accept rate. A software package is also developed to help researchers evaluate their systems using the defined protocols.

A Comparative Study of Gender and Age Classification in Speech Signals
Accurate gender classification is useful in speech and speaker recognition as well as speech emotion classification, because a better performance has been reported when separate acoustic models are employed for males and females. Gender classification is also apparent in face recognition, video summarization, human-robot interaction, etc. Although gender classification is rather mature in a...
متن کاملFace Recognition using an Affine Sparse Coding approach
Sparse coding is an unsupervised method which learns a set of over-complete bases to represent data such as image and video. Sparse coding has increasing attraction for image classification applications in recent years. But in the cases where we have some similar images from different classes, such as face recognition applications, different images may be classified into the same class, and hen...

Face recognition of an individual in a crowd is a challenging issue that has received the deserved attention during current scenario. This is a trivial task for brain, but cumbersome to be imitated artificially. The commonalities in faces does pose a problem on various grounds but features such as skin color, gender differentiate a person from the other. This can be attributed to its various ap...
متن کاملGender differences in crowd perception
In this study, we investigated whether the first impression of a crowd of faces-crowd perception-is influenced by social background and cognitive processing. Specifically, we explored whether males and females, two groups that are distinct biologically and socially, differ in their ability to extract ensemble characteristics from crowds of faces that were comprised of different identities. Part...
متن کاملReal-time Gender Classification
This paper introduces an automatic real-time gender classification system. The system consists of mainly three modules, face detection, normalization and gender classification. The LUT-type weak classifier based Adaboost learning method is proposed for training both face detector and gender classifier, and a Simple Direct Appearance Model (SDAM) based method is developed to detect the facial la...
