Various Obstruction Removal Techniques from a Sequence of Images
Main Article Content
Abstract
Reflection or obstruction from images is a major reason for quality degradation of images in image processing. Camera Flash is frequently used to capture a good photograph of a scene under low light conditions. However, flash images have many problems: The flash can often be blinding and too strong, leading to blown out images. This report presents separate algorithms described in the literature that attempts to remove obstructions computationally. The strengths and weaknesses of each algorithm outlined.
