An Approach For Gender Classification - 2480 Words

Abstract— In this paper, an approach for gender classification is carried out combining frontal face images, Haar cascades, Histogram of Oriented Gradients and Support Vector Machines. The comparison of the existing methods that delves into the effects of Haar Cascade Classifier and Histogram of Oriented Gradients(HOG) for Face Detection and the use of Support Vector Machines(SVM) for Gender Classification. A database of 2-D facial images was used, consisting of individual as well as group photographs. These images were used in face detection by Haar classifier and HOG and the results were compared at the end. Further, the detected faces were used to extract primary features on a face, such as, nose, eyes, lips, chin. Feature Extraction is used to calculate ratios, which differ for a Male and a Female. SVM uses these ratios in training and therefore classifying gender. Success ratio for HOG is found to be more than Haar Classifier and high accuracy is achievable with SVM. Keywords— Face Detection, Gender Classification, Haar, HOG, SVM 1. INTRODUCTION This paper presents novel approach to classifying gender from frontal facial images. Gender classification is one of the focuses of Human Computer Interaction (HCI) problem and has many potential applications. When we communicate with other people we process information about the person, such as the expression, gender, ethnicity and age. We hope human machine communication could flow more freely if the computer can comprehendShow MoreRelatedDefinition And Application Of Pattern961 Words   |  4 Pagesalready been in uses which are based on the pattern recognitions.

Their arguments are opposing to each other. Overall insists that both surgeries should be acceptable while Heyes does not agree with Overall. They both agree with that race and sex-gender are socially constructed. Thus, Overall has no problem with the concept of identity changes—for both sex-gender and race—however, Heyes argues that they are not constructed in the same way. Christine Overall is advocating the claim that transracial surgery is not problematic if transsexual surgery is acceptableRead MoreThe Archaeological Theory Of Practice1451 Words   |  6 Pagesconflict and did not allow space for the importance of ideas and beliefs.

Part V explains rather than the focus on humanity’s primary means of adaptation being the physical and social environment, there has been a more idealist approach that emphasizes the way in which individual actions shape culture, more specifically symbolic culture. These thinkers were influenced by the ideas of Durkheim in thatRead MorePrediction Of Age, Gender And Personality Traits Using Facebook Data958 Words   |  4 PagesPrediction of Age, Gender and Personality Traits Using Facebook Data Manali Bhalgat Introduction In the last decade, social networks like Facebook [1] have emerged as popular medium of social interaction and information dissemination. From a social web data mining perspective, Facebook stores a wealth of data about people and their interests.

Speech Disorders can be classified in many different ways. Each ‘model’ of classification focuses on a different aspect of speech such as the speech-processing chain model or criteria for the identification of speech disorder (Broomfield Dodd, 2004, cited in Dodd 2005). Although, the most commonly used system in clinical settings
