Abstract

The large volume of images used in Distance Learning System are desirable to be compressed in a proper ratio to reduce the storage loading of computer servers and provide better VOD (Video on demand) services. A new PCA-Wavelet based coding Scheme for Distance Learning image compression is proposed in this paper. It consists of 1) Principle Components Analysis (PCA)to reduce the information redundancies along temporal dimension and a texture energy (TE)based technique used to classify the image sequence so that the PCA is optimized to produce better representative PCA channels for our handout images. 2) Wavelet decomposition and optimized LEG algorithm for compression in spatial domain. The experimental results demonstrate that our proposed coding scheme achieves good performance.
