IntroductionMedical centers and hospitals use large amount of digital medical images for different purposes such as surgical and diagnostic plans.Teleradiology is the most advanced part of telemedicine.The radiologists interpret digital medical images while not physically present in the same location.Hence, these medical images need to be transmitted very fast and it required to store with a minimum capacity.Thus, image compression is used to reduce the redundancies in image and represents it in shorter manner to achieve efficient archiving and transmission of images.Image compression is the process of reducing irrelevant and the redundancy of the image data in order to store or transmit data in an efficient form.Image compression minimizes the size in bytes of an image without degrading the quality of an image to an acceptable level.Image compression techniques are broadly categorized into lossy and lossless compression techniques.Lossy image compression generates reconstructed image with some degradation, whereas lossless preserves image information.
