Implemented a Laplacian blob detector for Scale Space Blob Detection
- Generate a Laplacian of Gaussian filter.
- Build a Laplacian scale space, starting with some initial scale and going for n iterations: (a) Filter image with scale-normalized Laplacian at current scale. (b) Save square of Laplacian response for current level of scale space. (c) Increase scale by a factor k.
- Perform nonmaximum suppression in scale space.
- Display resulting circles at their characteristic scales.
