I have tried to retrieve training data using "objectDetectorTrainingData" from a ground truth object which was created using MATLAB 2017b image labeler (pixel-wise), and It doesn't give me an valid training data table/output.
However, it works fine when I used bounding boxes to select ROIs instead than pixel wise polygon. Could someone kindly help me to resolve this issue? I have attached my image, lebelling session and the ground truth object which I have received.
Many thanks in advance.
