Robust Representation and Recognition of Facial Emotions Using Extreme Sparse Learning

Robust Representation and Recognition of Facial Emotions Using Extreme Sparse Learning ABSTRACT: Recognition of natural emotions from human faces is an interesting topic with a wide range of potential applications, such as human-computer interaction, automated tutoring systems, image and video retrieval, smart environments, and driver warning systems. Traditionally, facial emotion recognition systems have been evaluated […]


Reversible Image Data Hiding with Contrast Enhancement

Reversible Image Data Hiding with Contrast Enhancement ABSTRACT: In this letter, a novel reversible data hiding (RDH) algorithm is proposed for digital images. Instead of trying to keep the PSNR value high, the proposed algorithm enhances the contrast of a host image to improve its visual quality. The highest two bins in the histogram are […]
