Image Edge Enhancement And Denoising Techniques For Computer Vision Applications
Anu Issac, Sudheesh Madhavan · 2015
Abstract — When dealing with images, denoising is an inevitable preprocessing part. The key in denoising also depends on the type of noises present in the image. There are different methods for denoising and the method suitable for computer vision application is chosen to be LOWESS and Savitzky-Golay smoothening techniques. Analyzing an image to extract the features of its contents require edge enhancement. Among the various types of techniques for enhancing the edges, Unsharp Masking is selected to suit the requirement for it gives good results. These methods can be used for the preprocessing phase of a vision processor or similar applications.
