Removing car shadows in video images using entropy and Euclidean distance features
Detecting car motion in video frames is one of the key subjects in computer vision society. In recent years, different approaches have been proposed to address this issue. One of the main challenges of developed image processing systems for car detection is their shadows. Car shadows change the appearance of them in a way that they might seem stitched to other neighboring cars. This study aims ...
متن کاملRemoving Shadows From Images using Retinex
The Retinex Theory first introduced by Edwin Land forty years ago has been widely used for a range of applications. It was first introduced as a model of our own visual processing but has since been used to perform a range of image processing tasks including illuminant correction, dynamic range compression, and gamut mapping. In this paper we show how the theory can be extended to perform yet a...
متن کاملFast Shadow Removal Using Adaptive Multi-Scale Illumination Transfer
In this paper, we present a new method for removing shadows from images. First, shadows are detected by interactive brushing assisted with a Gaussian Mixture Model. Second, the detected shadows are removed using an adaptive illumination transfer approach that accounts for the reflectance variation of the image texture. The contrast and noise levels of the result are then improved with a multi-s...
متن کاملRemoving Shadows from High-resolution Urban Aerial Images Based on Color Constancy
A method is explored to remove tall building shadows in true color and color infrared urban aerial images based on the theory of color constancy. This paper first uses the specthem ratio and Otsu threshold segmentation methods to detect building shadows on urban aerial true color and color infrared aerial images. Then, based on the shadow detection result, one of the color constancy algorithms ...
متن کاملDetecting and Removing Shadows
This paper describes a method for the detection and removal of shadows in RGB images. The shadows are with hard borders. The proposed method begins with a segmentation of the color image. It is then decided if a segment is a shadow by examination of its neighboring segments. We use the method introduced in Finlayson et. al. [1] to remove the shadows by zeroing the shadow’s borders in an edge re...
