Shadow removal using Retinex theory
2011 Third Chinese Conference on Intelligent Visual Surveillance, 2011Shadows in images always cause problems to computer visual tasks, so how to remove shadow is an important topic of image processing. In this paper, we propose a new shadow removal method based on Retinex theory. We firstly use the gradient edge detection combined with 1-D illumination invariant image to detect the shadow area, then remove the shadow ...

Removal of object’s shadow algorithm
2007 Asia-Pacific Conference on Applied Electromagnetics, 2007During bright day light or under strong lighting condition, shadows will appear and be part of an object in image. Objectpsila shadow in images may cause problem to several important algorithm in the fields of image processing such as object recognition, segmentation and object tracking.

Shadow removal from textured images
SPIE Proceedings, 2009Shadows and shadings are typical natural phenomena, which can often be found in images and videos acquired under strong directional lighting, such as those taken outdoors on a sunny day. Unfortunately, shadows can cause many difficulties in image processing and vision-related tasks, such like image segmentation and object recognition.

The Shadow Meets the Mask: Pyramid‐Based Shadow Removal
Computer Graphics Forum, 2008AbstractIn this paper we propose a novel method for detecting and removing shadows from a single image thereby obtaining a high‐quality shadow‐free image. With minimal user assistance, we first identify shadowed and lit areas on the same surface in the scene using an illumination‐invariant distance measure.

Shadow removal using contrast and illumination adjustable shadow model
2011 IEEE 19th Signal Processing and Communications Applications Conference (SIU), 2011Shadow can cause problems for image processing algorithms like object tracking and image segmentation. It is observed that, whenever a target enters a shadowed area, object tracking algorithms fail. To overcome that kind of problems, various methods are produced to find and remove shadows on images.
