Problem in OpenCV and HLS video library with hls::FASTX

Dear all, 

 

I am facing a problem using the HLS Video library. I am new on using HLS video library so apologies if the question is not clear.

 

Reading from here hls::FASTX ,  the FASTX function generating either a mask of corners, or an array of coordinates

 

But I have an application which uses FAST in openCV and the FAST function returns an array of keypoints which means that not only returns an array of coordinates but also other fields such as keypoint detector which is the response on the keypoint (the strength of the keypoint). more info here

So my question is how can hls::FASTX in HLS return except from the array of coordinates,  a vector of keypoints as described in the openCV documentation?

 

Thank you for your time,

Konstantinos.

Re: Problem in OpenCV and HLS video library with hls::FASTX

Have you seen this description using SDSoC, OpenCV and the HLS video library to implement FASTX as per XAP1167. Hope this helps

Re: Problem in OpenCV and HLS video library with hls::FASTX

Yes I saw that, but this is not reflected to the problem. The problem is that there different definitions about keypoints in the opencv documentation and hls library.

 

Thanks for your answer,

Konstantinos.
