Shadow Removal Algorithm Based on RGB Color Space

Abstract

Abstract-This paper aims to analyze and discuss shadow removal algorithm based on HSV and RGB color spaces. By subtracting the current image with the use of background image we detect the removal targets in the video. This technique becomes an essential component for the background extraction; in this paper the approach we adopt consist to use the traditional Gaussian background modeling method to extract background. However, due to the impact of light and other effects, all obtained foreground image containing shaded regions, and all moving targets detected automatically will be impacted. To perform the effect related to this issue, we introduce RGB Color data instruction to detect foreground shaded region, and then detecting also the real method of removal targets; this is an effective method.Index Terms-Gaussian background modeling, RGB color space shadow detection. I. SHADOW REMOVAL ALGORITHMAccording to the level of research in shadow detection-suppression field, a variety of Shadow Algorithm has been developed by researchers during last decade. In this paper we introduce two shadow removal algorithms: the HSV color space shadow removal algorithm and RGB color spaces shadow removal algorithm. We adopt the RGB color space model to create hybrid Gaussian and avoid the region containing shadow effects. And firstly, according to the Pixel attribute, the algorithm can proceeding by determining pattern matching judgment, and use the Gaussian Mixture model to determine shadow pixel. The experiments show that the shadow removal algorithm can be out performed [1]. A. Shadow Detection Algorithm ResearchConventionally, shadow removal technique can be divided into two categories which are attribute model and pattern model. Shadow algorithm based attribute model nevertheless is seen as simple operation; however the technique requires robustness and inaccuracy characteristics. This section introduces two models based on shadow removal algorithms: HSV and RGB color space shadow removal algorithm.
