Shadow Removal for Foreground Segmentation
2006Removing shadows casted by moving foreground objects in a scene is a critical problem for many vision-based applications. We propose two algorithms that examine color/texture invariants, and exploit spatial-temporal consistency to detect shadows efficiently and reliably.

Shadow Removal in Gradient Domain
2005Shadow removal is of significance in computer vision. Shadow usually adheres to texture, and it is difficult to decouple shadow from texture without any assumptions. In this paper, we suppose that the texture beneath shadow should bear the similar patterns, which makes the problem of simultaneously recovering the reflectance and light attenuation ...

Shadow Removal Using Bilateral Filtering
IEEE Transactions on Image Processing, 2012In this paper, we propose a simple but effective shadow removal method using a single input image. We first derive a 2-D intrinsic image from a single RGB camera image based solely on colors, particularly chromaticity. We next present a method to recover a 3-D intrinsic image based on bilateral filtering and the 2-D intrinsic image.

Object's Shadow Removal with Removal Validation
2007 IEEE International Symposium on Signal Processing and Information Technology, 2007We introduce in this paper, a shadow detection and removal method for moving objects especially for humans and vehicles. An effective method is presented for detecting and removing shadows from foreground figures. We assume that the foreground figures have been extracted from the input image by some background subtraction method.

Accelerated Shadow Detection and Removal Method
2019 IEEE/ACS 16th International Conference on Computer Systems and Applications (AICCSA), 2019Shadows can have a negative effect on the ability of computer vision techniques for object detection, tracking, and recognition. Therefore, ability to remove shadows and byproducts of illumination is an important problem to enable effective object recognition actions. As applications move into levels of higher information extraction and higher required

Moving Shadow Removal Based on ILT
2008 International Conference on Cyberworlds, 2008Moving shadows cause serious problem while segmenting and extracting foreground from video sequences, due to the misclassification of moving shadow as foreground. In order to detect the moving objects accurately, this paper proposes to remove the moving shadows based on the similarity between little textured patches.

Shadow removal from natural images
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010In this paper, we present a system for estimating the shadow field from a single natural image. The user of our system is provided with a broad brush to roughly specify the shadow boundary. As the user finishes drawing a stroke, the system starts to estimate the shadow field around the stroke and generates pretty accurate result even if the underlying ...
