Image compression is achieved by removal of one or three basic data redundancies: (1) coding redundancy, (2) spatial redundancy, (3) irrelevant information. This can be done by Huffman coding technique. In computer and information theory, a Huffman code is a particular type of optimal prefix ...

This paper discusses a medical application thatcontains a viewer for digital imaging and communications in medicine (DICOM) images as a core module.The proposed application enables scalable wavelet-based compression, retrieval, and decompression ofDICOM medical images and also supports ROI coding/decoding...
In this paper a feed forward Networks with Back propagation Algorithm adopting the method of steepest descent is used to minimize the performance error and a lossless coding technique i.e., Huffman coding to achieve better image compression ratio. The proposed method also includes Cumulative ...
image compressionPSNRFractal image compression can be obtained by dividing the original grey level image into unoverlappedblocks depending on a threshold value and the well known techniques of Quadtree decomposition. By usingthreshold value of 0.2 and Huffman coding for encoding and decoding of the ...
