中文说明：用matlab将一张图像感兴趣的某些范围，无缝的融入另一张图像中。使融入的图像没有明显的分割线处理整幅灰度图像的全局 Poisson 方法对前背景之间比较平滑的情况有很好的处理效果，F-B 的值在计算不透明度的梯度时有至关重要的作用，如果 F 和 B 的值差别较小，即图像前背景比较接近，则不透明度的梯度变化率会很大，也就是说α 的分布会很不平滑。
English Description：
An image with MATLAB are interested in certain ranges, seamless integration into another image. Makes into of image no obviously of segmentation line processing whole site gray image of global Poisson method on Qian background Zhijian compared smooth of situation has is good of processing effect, F-B of value in calculation not transparency of gradient Shi has vital of role, if f and b of value difference smaller, that image Qian background compared close, is not transparency of gradient changes rate will is big, that is alpha of distribution will is not smooth.
