Visual Speech processing is the key concern of researchers working in the field of speech processing and computer vision. Though earlier audio speech processing was popularly used for speech recognition but their performance deteriorated in the presence of noise. Moreover, variation in accent is another challenge that affects the performance of such(More)
Lip reading, also known as visual speech processing, means recognition of spoken word based on the pattern of lip movements while speaking.

Facial expression is the most natural way for the humans to convey their emotions with intensions. Facial expressions can be easily detected by human but for machines, it is very challenging task. In this paper, an approach for real time emotion detection is presented using real time graphic user interface for detection of emotion through a web camera. The(More)
This paper compares the performance of Relevance Vector Regression and Support Vector Regression for the purpose of facial expression recognition. The Support Vector Machine (SVM) is a state-of-the-art technique for regression and classification, but lacks the probabilistic treatment which is overcome by Relevance Vector Machine (RVM). Though SVM's have a(More)
