在 MATLAB Online 中打开

yes，sir，may be check the map，use

k = 1;

[im,map] = imread('https://ww2.mathworks.cn/matlabcentral/answers/uploaded_files/916049/1.gif');

if ~isempty(map)

im = ind2gray(im,map);

end

imwrite(im, sprintf('%d.jpg', k));

figure; imshow(im, []);

if use loop to prcess 310 images, may be use

% total 310 images.
for k = 1 : 310
    [im,map] = imread('your image file path');
    if ~isempty(map)
        im = ind2gray(im,map);
    end
    imwrite(im, sprintf('%d.jpg', k));
end
