I have a thermal image registered point cloud where the heated substance appears yellowish color and the other parts are black. Now I want to get a point cloud only with the points that has color yellowish and delete the other points that are black. The image of the point cloud that I have is attached.

You can use simple image segmentation techniques to segment out the yellow portions of the image. A very basic approach would be to threshold the image using the im2bw function by setting the threshold parameter close to the yellow marker.
