Image compression algorithms

SUMMARY Master Thesis Image Compression Algorithms Mustafa TÜRK Fırat University Graduate School of Natural and Applied Sciences Department of Electrical and Electronics Engineering 1998, Pages: 95 This thesis covers, application of various image compression techniques and wavelet transformation on image compression. Image compression is applied to reduce time and memory consumption during image recording and transmission. Compression also results with an image of better quality because of eliminating data redundancies of image. Computer simulation of a method called multiresolution analysis that eliminates pixel redundancies dividing an image into different sub-images was carried out using matlab programming language and applications for different compression ratios were realized. In this study, loosly image compression method and the loose variation versus compression ratio was examined. It was also discussed how to obtain better result with this method.
