Image compression using wavelets and vector quantization. in this paper, we discuss the technology of compression by the use of twodimensional image (2d) in digital formula depending. A survey and study of various image compression used in various image processing application has been presented. image compression plays a vital role in image processing, it is also very important for efficient transmission and storage of images. One of our aims with this research is to develop a compression strategy that allows for heterogeneous levels of com pression throughout the simulation domain while remaining consistent with vapor's use of the discrete wavelet transform. Abstract: this study presents a new approach for lossy medical image compression using vector quantization.
