Display Keypoints in VAD

Hi,

Currently, I am trying to create a simple program which will read image and extract key points using harris corner and draw keypoint in the image.

Using fread_image I have read the image and this image is fed to harris_corners node.

Now I want to know is there any nodes that I can use to display these key points.

(I have seen nodes to display line and rectangles, but could not  find anything to display points)

Hi Deepak,

You can use (only in VAD, it will not be generated to the code) the render kernel,

Or, you can run the graph in debug mode, in which case you can see the image output after each kernel if you hover with your cursor on the output line.

render_image will take only image as input.

My aim is to draw key points in the image and display it. Is there any node which will take image and keypoints as input and draws keypoints and displays it.

Hi Deepak,

there currently isn't a ready kernel.

You can write a user kernel doing that...
