need matlab code by applying LOG filtering on image using imfilter function.
Budget: $10 – $30 USD
As Laplacian filter can detect edges as well as noise, it may be desirable to
smooth the image first by a Gaussian filter to suppress the noise before using
Laplacian for edge detection. Laplacian of Gaussian (LOG) filter is a
combination of Laplacian filter and Gaussian filter. The 5*5 LOG filter is
defined as below.
[0 0 1 0 0
0 1 2 1 0
1 2 -16 2 1
0 1 2 1 0
0 0 1 0 0]
Please write a Matlab program to apply LOG filtering to Lena.bmp using
imfilter function and show the output image.
