Image transfer and storage require compression to reduce memory usage and increase transmission speed. In this article, the hybrid compression algorithm is used for color/black and white images. It includes the discrete wavelet transform and the Walsh transform. The Walsh transform coefficients are quantized and arithmetically encoded. The combined output is compressed and can be transmitted over any available network in the shortest time. The compressed image is decoded and the original image is decompressed using the inverse conversion operation.
