| Abstract: | In this paper, a triangular mesh model of image is constructed. Based on
multiresolution decomposition of the triangular mesh model, a new image compression
method is proposed. Multiresolution decomposition, compression and reconstruction
of image are implemented through multiresolution analysis of the triangular
mesh model of image. A new wavelet filter bank is constructed, which has never
been used in wavelet image compression before. The filter bank algorithm has O(n)
running time. The exprimental resnlts show that the proposed method can
achieve satisfactory image comprossion performance. |

| Keywords: | Triangular mesh image compression multiresolution analysis wavelet filter bank scalar space |
