In this paper, we discuss the implementation of shape based features, namely, Fourier descriptors and chain codes, for performing optical character recognition of binary images with application to Kannada handwritten characters. Invariant Fourier descriptors and normalized chain codes are obtained as features from preprocessed Kannada character binary images. Well known SVM classifier is used for...
A method for automatic facial expression recognition in image sequences, is introduced which make use of Candide wire frame model and active appearance algorithm for tracking, and Bayesian classifier for classification. On the first frame of face image sequence, Candide wire frame model is adapted properly. In subsequent frames of image sequence, facial features are tracked using active appearance...
