# Laplacian of Gaussian Filtering

Laplacian of Gaussian Filtering

This Demonstration shows the filtering of an image using a 2D convolution with the Laplacian of a Gaussian kernel.

This operation is useful for detecting features or edges in images.

The kernel is sampled and normalized using the Laplacian of the Gaussian function .

The standard deviation is chosen to be one fifth of the width of the kernel.
