In this paper we propose a new convex optimization framework for precise spatial noise shaping. The effectiveness of this new technique is demonstrated in the application of perceptual coding of images. A modified JPEG 2000 codec is implemented using the proposed new framework and compared with existing perceptual coding algorithms. Results of subjective tests show that the new framework can provide...
Three-dimensional video (3DV) technology is becoming increasingly popular, as it can provide high quality and immersive experience to end users. Huge amount of data for storage and transmission is an important problem to be solved. In this paper, an asymmetric MVC method is proposed. Color correction is first performed as a preprocessing step to provide consistent color information among views. Then,...
