Multiple output images from function
显示 更早的评论
The length of column 1 in bboxout is an unknown, how do I adjust my code to output each iteration of ROI_RGB?
If I use figure, imshow in the for loop each image is displayed, however I need to acces the data for each image seperately outside of the function.
function [ROI_RGB] = cleanup(bboxout, I1)
for i=1:length(bboxout)
%Crop out region of interest
ROI_RGB = imcrop(I1, bboxout(i,:));
end
end

Use cell array
function [ROI_RGB] = cleanup(bboxout, I1)
ROI_RGB = cell(1, size(bboxout,1));
for i=1:size(bboxout,1)
%Crop out region of interest
ROI_RGB{i} = imcrop(I1, bboxout(i,:));
end
end
You can access elements of cell array using brace indexing
ROI_RGB{1} % first element
ROI_RGB{2}
..
..
ROI_RGB{end}

I have updated the code. length() is actually an ambighious function. size() and numel() should be preferred over length().

Thanks for the help Ameer. The updated code is now giving me the below error I dont really understand, I think I need to do some more research into cell arrays!

ISoR is a cell array. To display an image, you need to use indexing
imshow(ISoR{1}) % display first image
imshow(ISoR{2})
