Lab#08:
“Study of basic sharpening filters”
Lab Objectives:
• To familiarize with and analyze different filtering techniques and compare their resultant
images.
• To apply sharpening filters on a gray scale image. It includes Laplacian filter, Robert
Gradient filter, Sobel filter etc.
• To perform edge detection of a gray scale image.
In lab tasks:
Task.1: Write a MATLAB code for Robert Gradient filter of an Image.
Code:
