opencv: Manipulating edge-detected pixels

I am new to opencv image processing.

My task is simple. I have a canny-edge detected image. I have to get rid of some edge-detected pixels. For example, at the coordinates of say (20,20), the edge-detected pixel should be eliminated.

Is there any possibility to get some solution?

I would be really thankful if any of you can guide me in solving this.

Thank you very much, Karthik

You can change the parameters of the Canny edge detection and tune them to your needs. If you only want a specific point or say finite specific knows points which you want to get rid off then just access the underlying pixel data and set it to 0. width = image.cols i = y-position, j = x-position image.data[i*width + j] = 0.

The canny output is just a binary black and white image. You can use the drawing methods to paint the pixels in black.
