I need to collect frame from kinect to implement feature extraction, but I don't know how to do it. I can get image by using iai-kinect2 and I know to process the kinect should subscribe RGB and depth rostopics but I don't know how to do it in coding.

Welcome! Your question is a little unclear (to me, at least). Are you asking how to subscribe to the RGB and depth topics?

I am doing a project to build a slam system using kinect. I have installed ros,libfreenect2... To get image to process(e.g.feature extraction), several webs said that topic should be subscribed for communicate ros with kinect. I don't know how to use the topic in coding
