1、《图像处理与分析》课程设计报告―――纸牌识别1、设计方案（原理）：纸牌识别主要涉及到模板匹配的相关问题，即将所选纸牌模板和源图象进行对比，以确定在源图象中是否存在也该模板相同或相似的区域，若该区域存在，还可确定其位置并提取该区域。模板匹配常用的一种测度为模板与原图象对应区域的误差平方。它与象素位置有关，但随象素变化。当模板和原图象中对应区域相匹配时取得最大值。纸牌识别是选取一定的模板，然后在14张纸牌中设定有效区域和推进速度逐一进行模板匹配，最后将最相似的区域所对应的纸牌找出来。此外，结合GUI设计，可大大提高可视化度。2、设计内容（代码）：functionvarargout=zzs_gui
