As ordinary image compression algorithm and the codec implemented in DSP or computer can not satisfy the demands of high speed image compression applications. Proposing an image compression algorithm for implementation on VLSI or FPGA with high performance becomes the key point of realizing high speed image compression. A low complexity image compression scheme based on Discrete Wavelet Transform (DWT) was proposed in this paper

which was based on 3 levels DWT

optimal quantization of DWT coefficients and a coder which combined adaptive zeros run-length coding and Exp-Golomb coding. This scheme was successful on low computational complexity

easy realization and achieving relatively high performance in compressing various images

which can be easily realized in FPGA for high speed image compression at 175Mpixel/s.
