MATLAB: Is there any way to extract objects after semantic segmentation

Question

this page: https://www.mathworks.com/help/vision/examples/semantic-segmentation-using-deep-learning.html showing example of semantic segmentation. Is there any way to extract (seprate) each object in a different image file?

Answer 1

Use ismember() to to extract the class you want from the labeled image, then process as normal:

thisClass = ismember(labeledImage, classNumberYouWant); % Get a binary image of this class ONLY
props = regionprops(thisClass, 'all'); % or whatever...
