Здравствуйте! Мне нужно написать программу, которая бы на рисунке распознавала букву "М". Я использовал алгоритм такой: Сначала все линии рисунка делаются толстыми, а потом подставляется в каждую точку рисунка шаблон буквы, в разных размерах. У меня получилось очень неоднозначно, часто ошибается и надо очень точно рисовать букву. Пожалуйтса, подкиньте идейку хорошего алгоритма, желательно не сложного, либо помогите оптимизировать мою прогу! Вот код: Код (Text): .586 .MODEL FLAT , STDCALL option casemap :none include \masm32\include\windows.inc include \masm32\include\user32.inc include \masm32\include\kernel32.inc include \masm32\include\gdi32.inc include \masm32\include\masm32.inc include \masm32\include\debug.inc includelib \masm32\lib\user32.lib includelib \masm32\lib\kernel32.lib includelib \masm32\lib\gdi32.lib includelib \masm32\lib\masm32.lib includelib \masm32\lib\debug.lib DBGWIN_DEBUG_ON = 1 ;turn it off if you don't want to include debug info into the program DBGWIN_EXT_INFO = 1 ;turn it off if you don't want to include extra debug info into the program WinMain proto :DWORD,:DWORD,:DWORD,:DWORD .data ClassName db "SimpleWinClass",0 AppName db "Распознавание",0 MouseClick db 0 Paint dd 0 m_x db 1,1,1,1,2,3,4,5,5,5,5,5 m_y db 2,3,4,5,2,3,2,1,2,3,4,5 scale dd 10 Counter dd 0 .data? hInstance HINSTANCE ?
