典型的LSB水印嵌入和提取算法，它是一个基本的matlab程序，可以帮助初学者入门 (typical LSB embedding and extraction algorithm, which is a basic Matlab procedures, Portal can help beginners)

大面积破损的基于样本块匹配的纹理合成修复图像(Large area damaged texture synthesis restoration image based on sample block matching)

说明：  计算凸包面积，点集Q的凸包是指一个最小凸多边形，满足Q中的点或者在多边形边上或者在其内。(Calculate convex hull area。The convex hull of point set Q is a minimum convex polygon, to meet the Q of the point or polygon or in its inside edge)

说明：  用2种方法，对text.png图像中的字母‘a’进行定位，给出定位结果以及位置坐标。(Two methods were used to locate the letter 'a' in the image of text. PNG, and the location result and position coordinates were given.)
