Image Compression is a process that involves transform a image from one form to another form. compression is used to minimize the size of image. Medical images are stored to study the case history of the patient. They take large disk space for the management to store. By the method of "Medical image compression" we reduce the disc space used by medical images ,without loss of information.
Image is decomposed into Spatial Orientation Tree (SOT) by using Discrete Wavelet Transform (DWT) transformation and applied Set Partitioning In Hierarchical Trees (SPIHT) algorithm to compress the image. The compressed image is stored as a file with extension of .cmp The compressed file is de-compressed into Inverse Discrete Wavelet Transform (I-DWT) forms and saved as BITMAP image, by applying vector encoding technique.
