In this paper, discussion on code redundancy algorithm using Huffman coding which chooses less number of bits for frequently occurring data for image compression is provided. The image compression and decompression models are provided with algorithms for easy implementation.Ajeet Kaur...
involvesextracting a given DICOM image into two segments, compressing the region of interest with a lossless,quality sustaining compression scheme like JPEG2000, compressing the non-important regions (background,et al.,) with an algorithm that has a very high compression ratio Adaptive Huffman. With...
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...
This research paper gives a recommended plan for medical image compression build on hybrid image compression proficiency (DWT and DCT).The objective for the wavelet coefficients of every DWT band(HH and LL) is to gain a hike on compression rates by exercising various compression thresholds whereas...

image compression techniquesHuffman codingwavelete.Image compression is now essential for applications such as transmission and storage in data bases. Compression becomes very easy techniques to apply without much technical requirement. In this paper we discuss about the image classification, wavelet ...
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 ...
