Digital Image Filtering

Artificial Intelligence & Information Analysis

Abstract

This lecture overviews Image Filtering, which is very important to ensure high image quality and image denoising.  It covers the following topics in detail: Image noise. 2D FIR filters, including Moving average filters. Spatial filters. Median filter algorithms. Digital filters based on order statistics, e.g., max/min filters and L-filters, Adaptive order statistic filters. Anisotropic Diffusion. Image interpolation.
