I am trying to use the OpenCV java wrapper and I am stuck with a problem: I apply a image operation to a source image and the result image is broken. It looks like some kind of ghosting which is caused by different line lengths.

Example This is an example using the blur operation. Something similar happens with drawContours as well.

What could be the problem? Has someone seen something similar?

So I've come across the exact same problem! I'm not sure what's causing it. I pass a grayscale image to blur or gaussianblur or canny and they all cause this odd ghosting. I'm just wondering if you were every able to solve this?

I guess that those operations only work on gray-scale images. They should check for the proper number of channels though.
