推荐答案

以下是文件夹中任意数量图像的通用代码.如果您确定每个文件夹有3张图片并且知道每个文件名的格式，则可以简化它.

Below is a generic code for any number of images in a folder. You can simplify it if you are sure to have 3 images per folder and you know the filename format for each.

%# Set the relative path for the database
basePath = 'Database/CASIA Iris Image Database (version 1.0)/';

for iFolder = 1:108
    %# Set current folder
    folder = sprintf('%s%03d/', basePath, iFolder);

    %# Find the image (e.g. bmp) files in the folder. Modify bmp for your needs.
    %#   and also modify 'left' string according to the subfolder of left images
    filenames = arrayfun(@(x) x.name, dir([folder 'left/*.bmp']),'UniformOutput',false);

    for iFile = 1:length(filenames)
        img = imread([folder filenames{iFile}]);

        %# and process the image
        %# ...

    end

    %# Modify the code for to run it for right folder
    %# ...
end
