Long coding time is the main problem in image compression based on Fractal at present, mainly due to its heavy computation of searching the best-match domain block for each range block. A fast compress image coding algorithm is proposed. At coding, the interpolation based on orthogonal multi-wavelets is used to compress the original image, and then use the basic fractal coding algorithm to compress;...
Image compression plays a crucial role in medical imaging, allowing efficient manipulation, storage, and transmission. Nevertheless, in medical applications the need to conserve the diagnostic validity of the image requires the use of lossless compression methods, producing low compression factors. In this paper, a novel near-lossless compression scheme for context based coding is proposed here and...
