Hello,

I have do some research about features detection and I manage to use ORB,SURF,SIFT correctly to dectect objects. But now, I have to write some explanation about how it works. I resume the work in few steps.

1. Detect Keypoints in image and template
2. Create Descriptors from the Keypoints
3. Matches the descriptors of image and template
4. Keep goodKeypoints from the matches
5. Find object from the good Keypoints

But there is some points I can't explain very well. What is a Keypoint ? What represent the descriptor of a Keypoint ?

For me a Keypoint is a point of interest detected thanks to methods(SURF,ORB,etc...) which is equivalent to point of interest a human being can see in a image, but i'm not sure if it's the correct definition.

Best regards
