資源簡介

字符包括漢字,字母,數(shù)字和一些符號。漢字有幾千個,字母有幾十個,數(shù)字的類最少只有10個,所以選擇簡單的手寫數(shù)字字符來實現(xiàn)。結合三個相關的程序和論文,一個是語音特征的分類(不調用神經網絡工具箱相關函數(shù)實現(xiàn)),另外兩個是關于手寫數(shù)字識別的。處理的數(shù)據(jù)集是放在10個文件夾里,文件夾的名稱對應存放的手寫數(shù)字圖片的數(shù)字,每個數(shù)字500張,每張圖片的像素統(tǒng)一為28*28

function?feature?=?feature_lattice(img)
%?輸入:黑底白字的二值圖像。輸出:35維的網格特征
%?======提取特征,轉成5*7的特征矢量把圖像中每10*10的點進行劃分相加,進行相加成一個點=====%
%======即統(tǒng)計每個小區(qū)域中圖像象素所占百分比作為特征數(shù)據(jù)====%
for?i=1:length(img);
bw2=im2bw(img{i}graythresh(img{i}));
