| Abstract(in English) | Segmentation image coding which decomposes an original image into some objective segments is an essential technique for next decade image coding. On segmentation coding, how objective texture images after segmentation are compressed is one of the important subjects. Recently, Komatsu etc. designed subband filter which optimize coding gain for image of AR process, and shows that coding gain for normal image improve about 0.5[dB]. But there are large differences among autocorrelation function of each texture image, and it was proposed that texture image coding by subband filter is designed according to each auto-correlation function. As a result, Coding Brodatz's texture image using 1-layer 5 taps filter, improved coding gain to 0.87[dB] and 1.5[dB] compared with AR model filter with 5 taps and orthogonal wavelet filter with 6 taps respectively. |
