摘要: 构造了图像的三角网格模型.基于三角网格模型的多分辨分解,提出了一个新的图像压 缩方法.通过图像的三角网格模型的多分辨分解、压缩与重构,实现了图像的多分辨解、压缩与重 构.构造了一个在小波图像压缩中未曾使用过的小波滤波器组,该小波滤波器组算法具有O(n)运 行时间.实验表明,该方法能获得较好的图像压缩性能.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.
