Two of the main areas of research in visual cryptography have been on improving the visual quality of the recovered image and in reducing the pixel expansion of the shares. This paper addresses both of these visual cryptography issues. First, a method to enhance the perceived visual quality of the recovered image using various image filtering techniques is presented. In particular, these image ...

The perceived quality of a synthetic visual speech signal greatly depends on the smoothness of the presented visual articulators. This paper explains how concatenative visual speech synthesis systems can apply active appearance models to achieve a smooth and natural visual output speech. By modeling the visual speech contained in the system’s speech database, a diversification between the synth...

Images are mainly viewed and analyzed by humans. Because of this, in the characterization image quality effectiveness processing, it is necessary to take into account peculiarities human vision system cognition that very complex. Saliency maps as well priority meaning introduced recently attempts incorporate specific features analysis processing fields. Many authors consider aforementioned them...
