Abstract

A compression of medical imagery is an important area of biomedical and telemedicine. For the medical application image study and data compression are quickly developing fields with rising application services and tele-radiology, tele-consultation bio-medical, tele-medicine and medical data analysis. The complexity involved in the processing of the medical images significantly differs from that of ordinary images. The ordinary natural scene images are taken from the generic digital image capturing devices, while the medical images are captured from a sophisticated image capturing devices. Hence a normal image processing algorithm are not directly applicable in medical images and requires some short of enhancement to fit for the extraction of the diagnosis origin of the medical images. Different algorithms are proposed in this paper like DWT and SPIHT, block based method DWT, DCT, DTCWT, arithmetic coding technique etc. In medical image compression, diagnosis and analysis are doing well simply when compression technique protect all the key image information needed for the storage and transmission. Image compression literally means reducing the size of the graphics file, without compromising on its quality. Image compression is required to minimize the storage space and reduction of transmission cost.
