2014-03-22 12:51:23 -0600 | asked a question | Laplacian filter and parameters I'm kind of new with opencv. I'm using Java and I'd like to know how to apply a Laplacian filter with alpha = 0.2, I mean, using this matrix to convolve: I'm using this code, but I don't know what to use as "ddepth" and "ksize": Imgproc.Laplacian(b, b_lapl, ddepth, ksize, 1, 0); Is there any quick form of getting the abs of the result? |
