基于matlab的字母识别系统

1、说明：A1.bmp图片为手写B的图片，其余为26个字母标准图片；draw_outline.m，Feature_Building.m，fsd.m，outline.m为主程序所调用的子程序。字母识别顺序结构程序如下：clcclearRGB1=imread(D:A1.bmp);RGB2=imread(D:A.bmp);RGB3=imread(D:B.bmp);RGB4=imread(D:C.bmp);RGB5=imread(D:D.bmp);RGB6=imread(D:E.bmp);RGB7=imread(D:F.bmp);RGB8=imread(D:G.bmp);RGB9=imread(D:H.b
