Facial expression recognition based on Local Binary Patterns
Classical LBP such as complexity and high dimensions of feature vectors that make it necessary to apply dimension reduction processes. In this paper, we introduce an improved LBP algorithm to solve these problems that utilizes Fast PCA algorithm for reduction of vector dimensions of extracted features. In other words, proffer method (Fast PCA+LBP) is an improved LBP algorithm that is extracted ...
متن کاملRadially Defined Local Binary Patterns for Hand Gesture Recognition
Hand gestures are extensively used in human nonverbal communication by hearing impaired and speech impaired people. To make communication between the hearing impaired and normal people simple and efficient, it is necessary that this process be automated. Number of techniques have been developed for automatic HGR. The usefulness of a method is analyzed based on various parameters like computatio...

Research into facial expression recognition has predominantly been applied to face images at frontal view only. Some attempts have been made to produce pose invariant facial expression classifiers. However, most of these atte...
متن کاملFacial Expression Recognition with Local Binary Patterns and Linear Programming
In this work, we propose a novel approach to recognize facial expressions from static images. First, the local binary patterns (LBP) are used to efficiently represent the facial images and then the linear programming (LP) technique is adopted to classify seven facial expressions—anger, disgust, fear, happiness, sadness, surprise, and neutral. Experimental results demonstrate an average recognit...
