Tutorial 36 - Image filtering in python - Total variation filter (TVF) for image denoising

In microscopy, Gaussian noise arises from many sources including electronic components such as detectors and sensors. In addition, salt & pepper noise may also show up due to errors in analog to digital conversion. Therefore, image denoising is one of the primary pre-processing operations that a researcher performs before proceeding with extracting information out of these images. This tutorial explains Total Variation Filter (TVF) and walks you through the process of writing a couple of lines of code in Python to implement the filter.
