Hi everyone, I have 97 uint8 jpgs (black and white) that I want to merge into a single jpg. However I need the final combined image to only be composed of cells from the series which are white.

I have tried using the imfuse command but it only works for 2 images and just over lays the images which is not what I need to do.

Any help would be greatly appreciated.

Well that's not right - why would you do that? Did you see my answer?

By the way, never use JPEG images when you need to do image analysis. Your pixels won't be just 0 and 255 - there will be in between values with jpg format. Use PNG format instead.

Thanks for the answer and the suggestion on output format. We normally don't use a visual format in our workflow but needed to in this particular instance. I will make a note of the .png suggestion for the future.

在 MATLAB Online 中打开

Just OR the binary images:

folder = 'c:\myimages'; % Whatever..
for k = 1 : numberOfImages
    filename = sprintf('image_%d.png', k);  % Whatever.
    fullFileName = fullfile(folder, filename);
    if exist(fullFileName, 'file')
        thisImage = imread(fullFileName);
        binaryImage = thisImage > 128; % Or whatever.
        if k == 1
            output = binaryImage;
        else
            output = output | binaryImage;
        end
    end
end
% If you want 0 and 255 instead of 0 and 1, set to 255 the "1" pixels
output(output== 1) = 255;
