This speaker-based emotion recognition system recognizes the four emotions namely happiness, sadness, fear and angry. Basically, aim of this system to recognize the emotions and estimate the various features namely formant frequency, energy, pitch and MFCC from speech signal. accuracy of emotion detection system using speech signal depends on types of feature used to extract unique characteristics in case of individual emotion recognition. emotions are showing effective changes in specific features and hence SVM (Support Vector Machine) classifier can show better performance. Individual emotion classification shows better performance in our work but in case of average it is considerably less i.e. 68%.

Several Biometric modalities research includes Fingerprint, Iris, Face and Retina recognition has got varying level of success. Our system is concerned with Thermal Imaging for Facial recognition. The convection type of heat transfer effect from the flow of hot arterial blood in vessels creates characteristic Thermal imprints [1]. Therefore when one acquires the Thermal image of Subject's face, it actually captures the vein structure of the face because the temperature of the skin is nothing but the temperature of underlying blood vessels [2]. We contribute, through this paper, to the design of thermal imaging framework able to do face recognition with unique feature extraction and Similarity measurements. The ...
