Image processing modifies pictures to improve, extract information and change their structure (composition, image editing and image compression etc.). Image can be processed by optical, photographic and electronic means, but image processing using digital computers are the most common methods because digital methods are fast, flexible and precise. Image Compression- reducing the redundancy in the image data to optimize transmission / storage. This paperoutlines the different types of image compression and lastly we compare the Differential Pulse Code Modulation (DPCM).
