Real-Time Image Compression Methods Incorporating Wavelet Transforms

摘要

The aims of the work described here are to develop and implement new generic image compression methods, based on the use of wavelet transforms and vector quantisation techniques, to achieve very high compression results whilst maintaining satisfactory image quality. A major problem with current wavelet-based compression methods is the large amount of computation reqired to process a single image. This problem is exacerbated with the requirement to process video sequences in real-time. We intend to use previously developed hardware/software co-design techniques to partition the compression and decopression algorithms between hardware and software implementations in order to maximise the copression performance at acceptable cost. The paper describes the different software and hardware architectures we propose to investigate.
