Multimedia is an evolving method of presenting many types of information. Multimedia combines text, sound, pictures and animation in a digital format to relate an idea. In future multimedia may be readily available as newspapers and magazines. The multimedia and other types of digital data require large memory for storage, high bandwidth In digital image processing, quality of an image is crucial to obtain high accuracy on features extraction,classification, identifying diseases etc. Diverse images have different storage acquisition.During Transmission, images may be corrupted due to obstruction in transmission channels.Images can be classified in to (1) Binary (ii) Gray Scale (iii) Color. Binary images [1] can be represented with only two values 0 (Black) & 1 (White). Binary image can also be classed as 1-bit image as it need only one byte for representing each pixel. These are repeatedly used where information is required only in the form of shape or general line. Mainly there are 5 formats for storing images. TIFF (Tagged Image File Format) - creates very large files and mostly used in Photoshop, Quark etc. JPEG (Join Photographic Experts group) - generally used for photographs on the web. These are the images that have been compressed to store large amount of data. GIF (Graphic Interchange Format) – compressed but lossless. PNG (Portable Network Graphics) – extensively used for web images. RAW image File- contains data from a digital camera and also contains a huge amount of data that is uncompressed
