LaplacianGaussianFilter

LaplacianGaussianFilter[data, r] convolves data with a Laplacian of Gaussian kernel of pixel radius r.

• LaplacianGaussianFilter[data, {r, σ}] convolves data with a Laplacian of Gaussian kernel of radius r and standard deviation σ.

Examples

Apply Laplacian of Gaussian filter to an image:

LaplacianGaussianFilter[ExampleData[{"TestImage", "Lena"}], 2]

Edge detection with custom radius:

LaplacianGaussianFilter[ExampleData[{"TestImage", "Mandrill"}], 5]

Specify radius and standard deviation:

LaplacianGaussianFilter[ExampleData[{"TestImage", "Peppers"}], {3, 1.5}]
