摘　　要：对在多个图象间进行非规则形状图象拼接的多分辨整合技术进行了研究。运用 Multi-masks方法将多个图象的选定区域同时融合在一起 ,减小了计算量 ,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 ,拼接图象平滑自然 ,效果较好。A mosaic technique for multiple images with irregular shapes was presented. A multi-masks method was proposed to treat the problem of blending the selected regions in several images almost seamlessly and reduce complexity of computation. With a multiresolution structure of multi-mask signals as the weighting functions, wavelet transform was used to synthesize images in different resolution level to reduce the effect of the seam. Experimental results for portrait images show that the combined image is smooth and almost seamless.
