Creating a feature detector with parameters?

[robertjpayne]

I'm trying to figure out how to create GoodFeaturesToTrackDetector but be able to specify the parameters it takes.

Going off the C++ documentation:

GoodFeaturesToTrackDetector( const GoodFeaturesToTrackDetector::Params& params=
                                            GoodFeaturesToTrackDetector::Params() );
    GoodFeaturesToTrackDetector( int maxCorners, double qualityLevel,
                                 double minDistance, int blockSize=3,
                                 bool useHarrisDetector=false, double k=0.04 );

It would seem we can do this but I cannot figure out how rbopencv is binding this properly.

I've tried:

cv::GoodFeaturesToTrackDetector.new
cv::FeatureDetector::GoodFeaturesToTrackDetector.new

But no luck.

Thanks!

Apparently OpenCV declares GoodFeatureToTrackDetector as GFTTDetector and uses a typedef to define GoodFeatureToTrackDetector which is not reflected by ropencv.

Therefore the syntax is: cv::GFTTDetector.new

I am going to add an alias and close the ticket when it is pushed.

Thanks! Appreciate the quick response, if I have more bindings questions/oddness should I post them up here or elsewhere?

Actually I found the Yard Docs which are incredibly helpful for mapping OpenCV documentation to the ruby api! Thanks a ton for this library!

To not hijack this ticket maybe you could open a new one with an appropriate name. In general everyone is more than welcome to post any improvements or suggestions.
