Hi,

I checked the documentation for image processing toolbox that lists all functions that can be used with Matlab Coder and saw no mention of regionprops(). http://www.mathworks.com/help/images/list-of-supported-functions-with-usage-notes.html

Does the above mean that I can't generate C++ code for regionprops using Matlab Coder?

Thanks,

-Vimal

Yes, it appears regionprops is not supported. What properties do you want to calculate?

Vimal, that's right. At the moment, regionprops does not support code generation. We have noted this as a possible future enhancement.

It would be really helpful if you can answer the following question:

What processor are you targeting? Are you generating code to run on a machine that can run MATLAB (like a Windows/Linux/Mac machine) or are you generating code to run on an embedded processor (like an ARM processor).

Thanks,

Anand

Have you tried using vision.BlobAnalysis system object in Computer Vision System Toolbox? It outputs fewer statistics than regionprops so you might have to calculate some statistics yourself using the label matrix.

Mean Intensity and Area should be pretty straight forward with supported ML code (it's just looping indexing and summing over your label image). The other two would require more effort.
