前言：本人旨在交流代碼，細(xì)節(jié)和原理不清楚的可以留言，以后做完了再整理，現(xiàn)在先放一部分，可以直接使用

1.代碼可以直接在c上運(yùn)行，輸入為5*5矩陣，比如數(shù)字0：

1 1 1 1 1

1 0 0 0 1

1 0 0 0 1

1 0 0 0 1

1 1 1 1 1

因?yàn)橛?xùn)練集合太小，決定用matlab生成大量訓(xùn)練樣本，放在后文中。

2.c語言實(shí)現(xiàn)代碼：（BP推導(dǎo)很簡單，不會的自己可以留言，代碼中有詳細(xì)注釋)

c語言程序運(yùn)行結(jié)果：

很明顯，對于輸入的矩陣完美判別（受到訓(xùn)練集合大小和圖像像素的影響，對于不規(guī)則輸入有很大誤差）

3.訓(xùn)練集合太小，所以我又研究了下matlab手寫輸入畫板，在matlab下新建圖形界面，傳送門：http://blog.sina.com.cn/s/blog_86a4e34a0102vxra.html，參考了這個(gè)代碼。

matlab手寫畫板.m文件幾個(gè)重要函數(shù)在傳送門直接可以用，使用效果如下：

這是打開的matlab手寫輸入板，自己寫的1，保存為bmp圖像，保存按鈕的代碼如下：（傳送門沒有）

% --- Executes on button press in pushbutton2. function pushbutton2_Callback(hObject, eventdata, handles) % hObject handle to pushbutton2 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) h=getframe(handles.axes1); imwrite(h.cdata,'output.bmp','bmp'); cla(handles.axes1);4.對于保存的圖像生成二進(jìn)制，matlab代碼如下：

clc; clear; filename = 'output.bmp'; %讀出源文件 imfinfo(filename) % 查看圖像文件信息 imgRgb = imread(filename); % 讀入一幅彩色圖像 imshow(imgRgb); % 顯示彩色圖像 imgGray = rgb2gray(imgRgb); % 轉(zhuǎn)為灰度圖像 figure % 打開一個(gè)新的窗口顯示灰度圖像 imshow(imgGray); % 顯示轉(zhuǎn)化后的灰度圖像 % imwrite(imgGray, 'gray.jpg'); % 將灰度圖像保存到圖像文件 thresh = graythresh(imgGray); %自動(dòng)確定二值化閾值 I = im2bw(imgGray,thresh); %對圖像二值化 ci=imresize(I,[16,16]); %把a(bǔ)i轉(zhuǎn)成256x256的大小 ti =~ci;%對圖像取反 figure imshow(ti)%畫取反后的圖 figure imshow(ci)%畫壓縮后的二進(jìn)制 figure imshow(I); %畫二進(jìn)制圖結(jié)果如下：

左到右依次為原圖、灰度圖、壓縮后的二進(jìn)制圖，原本二進(jìn)制圖，我們需要的數(shù)據(jù)就存儲在二進(jìn)制圖的數(shù)組里面16*16大小，可以弄大一點(diǎn)，這樣對于輸入的判斷會更準(zhǔn)。

本文缺陷：1.c語言中讀入訓(xùn)練集合和測試集合應(yīng)改為文件流操作，這樣對于大量數(shù)據(jù)文件的訓(xùn)練和測試會很方便，matlab 生成圖像文件和二進(jìn)制文件可以直接改為文件操作，時(shí)間有限感興趣的可以基于我的demo改，希望能共同學(xué)習(xí)共同進(jìn)步！！！

結(jié)束語：c語言實(shí)現(xiàn)只是我測試的一個(gè)東西，我的目的是用ASIC集成電路實(shí)現(xiàn)，下一步將在fpga使用verilog語言實(shí)現(xiàn)這個(gè)手寫輸入識別！敬請關(guān)注！

文中多有瑕疵和漏洞，歡迎指教！
