Non-Maximum Suppression #12

Open DeveloperPaul123 opened 8 years ago

DeveloperPaul123 commented 8 years ago

Need to use atomics to properly set values to the output in the image for non-maximum suppression.

Instead of performing traditional non-maximum suppression, I will be using the zero crossing method using a second derivative (Laplacian of a Gaussian filter) kernel with a single convolution. I'll need to use the direction data to find zero crossings.
