Up: Noise Estimation and Removal
Previous: Introduction and Aim
Apply the tangential filter tsmooth to the image and estimate the reduction in image noise.
This filter smooths along the tangential direction to local edge structure in each pixel.
Again, repeat this for various noise levels.
- You should be able to determine an approximate constant factor of reduction. What is it?
- Compare the result with Gaussian smoothing; where are the largest differences between the
resulting images and why?
