以101_ObjectCategories數(shù)據(jù)庫為例，將9144張圖像的存儲路徑保存在兩個文本文件中，一個為訓(xùn)練集，一個為測試集，并在每張圖像后添加對應(yīng)類別標(biāo)簽。最后打亂順序。
1. 準備好101_ObjectCategories數(shù)據(jù)庫

2. 打開MATLAB，添加extract.m腳本，運行。extract.m代碼如下

%trian test clc; ParentFolder='J:\Dataset\101_ObjectCategories\'; %matlab在本地數(shù)據(jù)庫生成list所以路徑是反斜杠 ParentPath = dir(ParentFolder); NumFolders = length(ParentPath);train= fopen('train.txt','wt'); test = fopen('test.txt','wt');for i = 3:NumFolderslabel=num2str(i-3);FolderPath = [ParentFolder ParentPath(i).name];imageName=dir(FolderPath);numPic=length(imageName);count=1;index = randperm(length(imageName)-2);for k = 1:4index = randperm(size(index,2));end for j=3:numPicsrc=['/' ParentPath(i).name '/' imageName(index(count)+2).name]; %Ubuntu系統(tǒng)下讀取list，路徑是斜杠if count<=15fprintf(train,'%s %s\n',src,label);elsefprintf(test,'%s %s\n',src,label);endcount=count+1;end end fclose(train); fclose(test);

3.對生成的list進行打亂，代碼：

fidin_train=fopen('train.txt'); fidout_train = fopen('train_rand.txt','wt'); fidin_test = fopen('test.txt'); fidout_test = fopen('test_rand.txt','wt'); index =0; str_train = cell(1); while ~feof(fidin_train) tline=fgetl(fidin_train);index =index+1;str_train{index} = tline; endrand_index = randperm(index);for i=1:indexfprintf(fidout_train, '%s\n',str_train{rand_index(i)}); endindex = 0; str_test = cell(1); while ~feof(fidin_test) tline=fgetl(fidin_test);index =index+1;str_test{index} = tline; endrand_index = randperm(index);for i=1:indexfprintf(fidout_test, '%s\n',str_test{rand_index(i)}); end

總結(jié)

以上是生活随笔為你收集整理的matlab生成图像路径列表和标签，打乱顺序的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
