In present day technology human-machine interaction is growing in demand and machine needs to understand human gestures and emotions. Expand

We use the concept of embedding two watermarks into the cover image by actually embedding only one, to authenticate the source image and protect the watermark simultaneously. Expand

In this paper, two approaches viz., cropped face and whole face methods for feature extraction are implemented separately on the images taken from Cohn-Kanade CK and JAFFE databases. Expand

In this paper, we have proposed a method based on geometric features, considering images of 7 yaw angles (-45°,-30°,-15°,0°,+15°) from BU3DFE database. Expand

A technique for emotion recognition from facial expressions in images with simultaneous pose, illumination and age variation in real time is proposed in this paper. Expand

A Convolution based parallel and pipelined architecture using MAC Loop Based Filter (MLBF) is proposed in this work. Expand

We propose an architecture for convolution based DFT and its FPGA implementation. Expand

The aim of this paper is to develop an algorithm to enhance speech recognition of a stuttered speech by removing prolongation(s) from the sample. Expand

The objective of this paper uses a combination of Dynamic Time Warping (DTW) and prosody manipulation to inter-convert emotions among one another and compares with neutral to emotion conversion using objective and subjective performance indices. Expand
