| Abstract: | ABSTRACTIn this paper, a region of interest coding using partial-SPIHT (P-SPIHT) is proposed. P-SPIHT evaluates theprobability of the significant coefficients (P1) in each bitplane. Then it codes each bit plane independently andaccording to its P1. The proposed algorithm codes theROI region first and then it codes the backgroundindependently. The algorithm uses integer-to-integershape adaptive discrete wavelet transform (ISA-DWT)which has the flexibility of transforming any number ofisolated arbitrary shape ROI regions. The results showthat compression of the proposed algorithm is superior tothe ROI-based SPIHT coder. | ||
