| Research Abstract |
The goal of this study is to reveal the theoretical lossless compression boundary for image signals,and to develop the basic concept of scalable transmission system for super-high resolution moving images. The image coding scheme is separated into two parts, that is to say,one is a signal conversion part and another is an entropy coding part. In this study,we proposed new methods for each part. First,as a signal conversion part, we proposed an inter frame coding method with motion compensation and Markov model. Next, we proposed a fast multi-frame interpolation method. Also we studied on an entropy coding using arithmetic coding with the extension of the information source.
