Ground Truth Labeler App (Matlab R2021b) - How to export ground truth image with color-labeled?

Hi,

I am following this example, Semantic Segmentation Using Deep Learning (https://www.mathworks.com/help/vision/ug/semantic-segmentation-using-deep-learning.html)

I have tried to manually label from one of the image below,

and I got this black image, and I already adjust the image using imadjust function, (resulted in grayscale image),

What should I do to obtain the image groung truth such as below? I just want to generate Pixel Label with color label

Thank you

You can use label2rgb():

% Apply a variety of pseudo-colors to the regions.
coloredLabelsImage = label2rgb (labeledImage, 'hsv', 'k', 'shuffle');
% Display the pseudo-colored image.
imshow(coloredLabelsImage);
