Indoor shadow detection for video segmentation
2004 IEEE International Conference on Multimedia and Expo (ICME) (IEEE Cat. No.04TH8763), 2005To prevent moving cast shadows from being misunderstood as part of moving objects in change detection based video segmentation, this paper proposes a novel approach to cast shadow detection based on the edge and region information in multiple frames. First, an initial change detection mask containing moving objects and cast shadows is obtained. Then, a

Shadow Detection by Integrating Multiple Features
18th International Conference on Pattern Recognition (ICPR'06), 2006Cast shadows of moving foreground objects in a scene often result in problems for many applications such as surveillance, object tracking/recognition, video content analysis and intelligent transportation systems. In this paper we presented an algorithm exploiting information of color, shading, texture, neighborhoods and temporal consistency to detect ...

Research on method for moving shadow detection
2017 12th International Conference on Intelligent Systems and Knowledge Engineering (ISKE), 2017In the field of video tracking, the shadow will seriously interfere with the moving foreground extraction. As the moving shadow recognition has always been an inevitable topic in the video tracing field, this paper researches three kinds of traditional shadow detection algorithm and some improvement ideas and methods, and analyzes the advantages and ...

Spectral anomaly detection in deep shadows
Applied Optics, 2010Although several hyperspectral anomaly detection algorithms have proven useful when illumination conditions provide for enough light, many of these same detection algorithms fail to perform well when shadows are also present. To date, no general approach to the problem has been demonstrated.

Shadow of an Exoplanet Detected
Science, 1999ASTRONOMYFor the first time, a planet in another star system has been seen to cross the face of its parent star. The transit, as it is called, is the most direct glimpse yet of an extrasolar planet. It has also allowed astronomers to pin down the object's mass, size, and density--characteristics that could only be guessed before--which leave little ...

Workpiece localization with shadow detection and removing
2013 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2013This paper presents a new approach to detect and remove the shadows for workpiece localization, which is with an extensive application in automatic assembly system. However, the shadows of workpiece will badly affect this procedure as the contour of the shadow has the same shape with the workpiece itself in the image. The localization system treats the

Detecting shadows from a single image
Optics Letters, 2011We present a novel (to our best knowledge) optical recognition technique for detecting shadows from a single image. Most prior approaches definitely depend on explicit physical computational models, but physics-based approaches have the critical problem that they may fail severely even with slight perturbations.
