Abstract

In this paper, a region of interest coding using partial-SPIHT (P-SPIHT) is proposed. P-SPIHT evaluates the probability of the significant coefficients (P₁) in each bit plane. Then it codes each bit plane independently and according to its P₁. The proposed algorithm codes the ROI region first and then it codes the background independently. The algorithm uses the integer-to-integer shape adaptive discrete wavelet transform (ISA-DWT) which has the flexibility of transforming any number of isolated arbitrary shape ROI regions. The results show that compression of the proposed algorithm is superior to the ROI-based SPIHT coder.
