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 ...
The classic image compression techniques have serious limitations at high compression rate. 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 ...
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...
Fractal 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 image these techniques...
HuffmanCoding
Huffman coding is a method of data compression that is independent of the data type, that is, the data could represent an image, audio or spreadsheet. This compression scheme is used in JPEG and MPEG-2. Huffman coding works by looking at the data stream that makes up the file to be com...
