Wavelet based efficient color image coding technique
Ekram Khan, M. Ghanbari · Proceedings - International Conference on Image Processing · 2003
This paper proposes a wavelet based efficient and embedded color image coding technique. It extends the use of virtual set partitioning in hierarchical trees (VSPIHT) for color images. In this technique the coefficients of chrominance planes are linked together through composite trees having roots in the virtual LL band of luminance component. The virtual decomposition is performed in the luminance plane only. The simulation results show the improved performance of the proposed technique compared to the color SPIHT (CSPIHT) as well as the technique which uses virtual decomposition in each of the color planes.
