C code generation for extractFeatures() and matchFeatures()

Hello,

I am generating C code from .m file using MATLAB coder. I am generating c code for matchFeatures() and extractFeatures().

I am calling detectSURFFeatures() function to get the cornerPoints.Then extract the features from these cornerPoints and match those features.

When i do this I am getting an error saying that

detectSURFFeatures() is not supported for code generation.

I would like to know whether detectSURFFeatures() is supported in MATLAB coder. I need to use one of the feature detection method to obtain the features.

I am sending here the screen shot for the error details.

Looking forward to hear from you.

Thanks Pankaja

Hello,

when you look at the documentation you can find this : detectSURFFeatures Computer Vision System Toolbox Supports MATLAB Function block: No Generates portable C code using a C++ compiler that links to OpenCV (Version 2.4.9) libraries. Portable C Code Generation for Functions That Use OpenCV Library

same thing for matchFeatures function (with the 'approximate' option, it works find otherwise). I don't know why the C code with OpenCV is not generated (maybe it's an option, I'm a beginner with matlab Coder)

take a look at this example, it use the extrinsic option to call the matlab runtime maybe it can usefull for your application.
