Abstract :
In this paper, we proposes A type Image Coding which is an experimental still image compression system that combines intra frame block prediction algorithms from the H.264 standard and Wavelet-Based Contourlet Transform(WBCT) with SPIHT image compression technology, followed by context adaptive binary arithmetic coding (CABAC) as used in H.264. The image compression algorithm using Wavelet-Based Contourlet Transform(WBCT) with modified SPIHT can effectively code image with more discontinuities along curve lines. Predicted image is subtracted from original image to give residual image, residual image has lots of discontinuous curve lines, it is typically 2-dimensional and curve singularities image. The result of the image coding compression scheme perform is much better than JPEG and AIC and almost is the same with JPEG-2000.
