Right now:
* Edge-Detect
* Difference of Gaussians...
* Edge...
- Sobel (type: gradient)
- Prewitt (type: compass)
- Gradient (type: gradient)
- Roberts (type: gradient)
- Differential (type: gradient)
- Laplace (type: gradient usually used with
Laplacian of Gaussian)
* Laplace...
* Neon...
* Sobel...
What I suggest:
* Edge-Detect
* Difference of Gaussians...
* Gradient...
- Roberts
- Sobel
- Prewitt
- Isotropic
* Compass...
- Sobel
- Kirsch
- Robinson
- Prewitt
* Laplace...
* Neon...
Remove Laplace from edge.c (doesn't seem correct to me)
Merge Sobel.c in Gradient...
Prewitt from edge.c is moved to Compass and with more options for kernels.
