Laplacian of Gaussian: how does it work? (opencv)
- by maximus
Does anybody know how does it work and how to do it using opencv?
Laplacian can be calculated using opencv,
but the result is not what I expected.
I mean I expect the image to be approximately constant contrast at background regions, but it is black, and edges are white. There are a lot of noise also, even after gauss filter.
I filter image using gaussian filter and then apply laplace.
I think what I want is done by a different way.
