摘　　要：本文提出一种针对非规则形状图象拼接的变形合成技术 ,即分区分步地运用多项式映射函数对图象进行变形处理 ,使拼接区域的边缘一致 ,并利用小波变换对图象进行多分辨分解 ,采用与频段宽度成正比的加权拼接宽度来消除拼缝的影响。实例表明 ,拼合图象平滑自然 ,效果较好。A morphing and mosaic technique is proposed in this paper By means of partition and transition of frames,a mapping al gorithm of image morphing based on polynomial functions is applied to align the contour of mosaic images With a multiresolution structure of mask signals as th e weighting functions,wavelet transform is used to combine images of different r esolution levels to reduce the effect of the seam The experiment shows the avai lability of this technique
