Wavelet Based Medical Image Compression For Telemedicine Application

In this paper, we discuss about a simple and lossless compression method for compression of medical images. Method is based on wavelet transform of medical application. Wavelets provide a mathematical way of encoding information in such a way that it is layered according to level of detail. These approximations can be stored using a lot less space than the original data. Here a low complex 2D image compression method using wavelets as the basis functions and the approach to measure the quality of the compressed image are presented. By using this coding method the compressed bit stream are all embedded and suited for progressive transmission. The reconstructed image is synthesized using the estimated detail matrices and information matrix provided by the Wavelet transform. In this paper, different wavelets have been used to perform the transform of a test image. The compressed image can be accessed and sent over telemedicine network.
