I am trying to find a way to evaluate the performance of my fruit detection algorithm. The detection of the fruit is currently done with the circular Hough transform. How can I compare this result with the original RGB image and therefore check if the detected fruit are a true positive or a false positive (to calculate the accuracy)? And how is it possible to train the algorithm?

I have added the original RGB image, the black-white image after preprocessing and the parameters of the CHT algorithm.

[centers,radii, metric] = imfindcircles(BW_Canny,[Rmin Rmax],'Sensitivity',0.95,'EdgeThreshold',0.15); % 0.95 0.15
% d = imdistline; %To check manually the approximate radius of the fruit in the image
viscircles(centers, radii,'EdgeColor','b');
