Image Labeler - Export problem (bug?)
1 view (last 30 days)

I used the Image Labeler app to define 3 ROI labels. Then, I exported the labels (Export to file - function) that also generated a new folder called ('PixelLabelData') containing PNG label files. There are two problems I found:
1. The generated .PNG labels appeared black. However, they should be pseudo-colored according to the 3 ROI labels that I defined.
2. When I export the session file in OSX and tried to import them back in WIN, the defined ROIs categories are embedded but the overlay are lost.
Any explanation for this issue? Any help is much appreciated.

To view the ROI's in your (black) images, use:
I = imread('PathToYourBlackImage');
figure;
Im = imagesc(I);

Matlab labels your three ROIs with values 1, 2 and 3. And the background is zero. So you should use imagesc in order to display the image with scaled colors. https://es.mathworks.com/help/matlab/ref/imagesc.html
>> image = imread('PixelLabelData\Label_1.png');
>> figure;
>> imagesc(image);
