Question

例如，我的目录中有100个图像，其中'x'图像相同，我想知道x的值。

Answer 1

如果我理解你的问题，并且你想要做的就是计算一些图像与某些目标图像完全相同，那么这应该有用......

%directory where images are stored
directory = 'Directory_To_Images';
files = dir(directory);

%total number of matches
numMatches = 0;

%The Real image, the image you wish to test against
RealImage = imread('Target_Image.jpg');

%go through all files in the directory
for i = 1 :  length(files)
[pathstr,name,ext] = fileparts(files(i).name);

%test to make sure its a JPG image (you may need to modify this if you have
%multiple file types
if (strcmp(ext,'.jpg'))
    %check if the images match
    if(isMatch(RealImage, [directory '\' name ext]))
        numMatches = numMatches+1;
    end
end
end

sprintf('Number of matches: %s', num2str(numMatches))

这是缺失的功能：

function[result] =  isMatch(RealImage, TestImage)

testImage = imread(TestImage);
if (sum(sum(sum(RealImage == testImage))) == size(RealImage,1) * size(RealImage,2) * size(RealImage,3))
    result = true;
else
    result = false;

end

Answer 2

% Reference image
img_ref = imread('img_ref.jpg');

% Create an variable for alloc the path
img_path ='/your/dir/of/images/'

% Create an variable struct, for searching files with .jpg extension 
names = dir(fullfile(img_path, '*.jpg'));


% Counts the number of images on the path
n_imgs = numel(names); 

for n = 1:n_imgs
    full_name = fullfile(img_path, names(n).name);
    your_imgs = imread(full_name);

    r = isMatch(img_ref,your_imgs);
    disp(r)
end
