I am new to using OpenCV and pardon me if this has been asked before.
I have a set of polygons in 2-D with their respective endpoints. I have started learning CV and finding out which features like roundness, area, perimeter, elliptic fit, etc.. can be computed using the inbuilt functions in CV.
Also, please suggest me any interesting features that can I can compute from a set of polygons of irregular sizes. (say one polygon has only 4 end points and another might have 10 endpoints and so on randomly).
Thanks for the help!!!Thu, 06 Nov 2014 18:14:42 -0600http://answers.opencv.org/question/46648/all-features-that-can-be-computed-using-points-of-a-polygon/Comment by rwong for <p>Hi,

http://answers.opencv.org/question/46648/all-features-that-can-be-computed-using-points-of-a-polygon/?comment=46652#post-id-46652The set of polygon descriptors operations supported by OpenCV are [documented here](http://docs.opencv.org/modules/imgproc/doc/structural_analysis_and_shape_descriptors.html). If you would like to know shape descriptors not supported by OpenCV, I would encourage you to get a Master or Doctoral Degree in Computer Vision with a Minor in Mathematics and make that [your thesis topic](http://www.math.wisc.edu/~boston/ICASSP-update.pdf).Thu, 06 Nov 2014 18:34:46 -0600http://answers.opencv.org/question/46648/all-features-that-can-be-computed-using-points-of-a-polygon/?comment=46652#post-id-46652Comment by akhi for <p>Hi,

If this is what matches my interests, I would definitely consider ur suggestion. :)Sun, 09 Nov 2014 11:05:30 -0600http://answers.opencv.org/question/46648/all-features-that-can-be-computed-using-points-of-a-polygon/?comment=49970#post-id-49970
