Empty row of pixels in the top and bottom of the nonmax suppressed gPb #5

Open acherunilam opened 7 years ago

All of the 8 oriented gradient gPb files are fine, but the nonmax suppressed file always has the top most and bottom most rows empty, regardless of the input image. Is this a bug?

On a related note, we've attempted to fix this by padding the image with a border of zeros and discarding the padded pixels after damascene finishes computing. It doesn't work, as it ends up adding more noise at the image boundary.
