How to apply a Color Thresholder function in Image Batch Processor

John Williams answered . 2025-07-03 22:09:39

folder = pwd; % Whatever.
filePattern = fullfile(folder, '*.png');
fileList = dir(filePattern);
for k = 1 : numImages
    % Read in original image
    thisFileName = fullfile(fileList(k).folder, fileList(k).name);
    fprintf('Reading "%s".\n', thisFileName);
    rgbImage = imread(thisFileName);
    % Do color segmentation.
    [mask, maskedRGBImage] = createMask(rgbImage);
    % Now display the three images
    subplot(2, 2, 1);
    imshow(rgbImage)
    subplot(2, 2, 2);
    imshow(mask);
    subplot(2, 2, 3);
    imshow(maskedRGBImage);
    drawnow;
end

Or if you're using the batch processing app, maybe it's using only the first output. Try reversing the outputs:

function [maskedRGBImage, BW] = createMask(RGB)
