Shadow Elimination for Effective Moving Object Detection with Gaussian Models
This paper presents a coarse-to-fine approach to eliminate unexpected shadows of multiple pedestrians from a static and textured background using Gaussian shadow modeling. At the coarse stage, a moment-based method is proposed to estimate the rough boundaries between shadows and moving objects. Then, at the fine stage, the rough approximation of shadow region provides a key to model shadows. Th...
متن کاملMoving Shadow Detection in Video Using Cepstrum
Moving shadows constitute problems in various applications such as image segmentation and object tracking. The main cause of these problems is the misclassification of the shadow pixels as target pixels. Therefore, the use of an accurate and reliable shadow detection method is essential to realize intelligent video processing applications. In this paper, a cepstrum‐based meth...
متن کاملReal-time moving object detection and shadow removing in video surveillance
In automatic video monitoring, real-time detection and in particular shadow elimination are critical to the correct moving objects segmentation since they severely affect the surveillance process. In this study, we propose a fast and flexible approach of movement detection based on an adaptive background subtraction technique with an effective model of shadow elimination based on color constanc...
متن کاملMoving Shadow and Object Detection in Traffic Scenes
We present an algorithm for segmentation of traffic scenes that distinguishes moving objects from cast shadows. Three image features at each pixel site are considered: brightness, and normalized red and blue color components. Each feature is analyzed by an a posteriori probability estimator that computes membership probabilities for the three classes: background, foreground and shadow. The algo...
متن کاملMoving Object Detection for Video Surveillance
The emergence of video surveillance is the most promising solution for people living independently in their home. Recently several contributions for video surveillance have been proposed. However, a robust video surveillance algorithm is still a challenging task because of illumination changes, rapid variations in target appearance, similar nontarget objects in background, and occlusions. In th...
