Pls I'm having issues getting my confusion matrix done. Below are all code-files and picture '1.jpg' is NOT a monochrome image. On plotting the confusion matrix, it keeps giving me
'matrix dimensions must agree'
thank u for the quick response.

I see that your code requires the file '1.jpg' in order to execute. Could you please attach the file so that I can try to reproduce the error?

Given that the input image is not a monochrome image, all elements in your "segmented_images" cell array have three dimensions. However, the polygonal ROI image you create (stored as variable "BW_1") has two dimensions. Plugging the two types of variables into the MATLAB "confusion" function causes an error since the two arguments are expected to have the same number of dimensions.
The above conclusion is obtained from my interpretation of your code. If I misunderstood your code, please let me know.
