Core Image Coding Based on WP-EBCOT

This paper proposed a new core image coding algorithm based on Wavelet Packet Embedded Block Coding with Optimized Truncation (WP-EBCOT), for the characteristics of rich textures and complex edges in the core images. The entropy-based algorithm for best basis selection is used to decompose the core image, and then the wavelet packet subband structure is tested by EBCOT with various different code blocks size, as a result we find that the optimal size of the code blocks is 64*64. Results show that the proposed algorithm outperforms the base-line JPEG2000 for PSNR, and provides better visual quality for core images.
