outline

• Denoising
• Bilateral filtering
• Trilateral filtering
• Reference

3
Denoising

• Detect noise
• Gaussian noise
• Impulse noise
• Others
• Remove noise
• Gaussian filter
• Other techniques

4
Bilateral filtering

• Two components
• Spatial
• Radiometric
• Functionality
• Remove gaussian noise preserve edges
• Advantages
• Not iterative
• Easy to implement

5
Bilateral filtering(cont.)

• For a gray level image, remove gaussian noise
  preserve edge.

6
Bilateral filtering(cont.)
7
Trilateral filtering

• Add the ability to detect remove impulse noise.
• Three components
• Spatial
• Radiometric
• Impulse detection factor
