LaplaceEdgeImg

DESCRIPTION

Performs a 2D convolution on an image using a predefined 3x3 Laplace kernel. The resulting image is edge enhanced. The convolution kernel is 
  0  -1   0
 -1   4  -1
  0  -1   0
Edge detection by convolution with a Laplace kernel is discussed in: Digital Image Processing, Gonzales, R.C., Wintz, P., Addison Wesley, Second Edition, 1987, pp 338--340.
