Shadow detection using color and edge information. [PDF]
, 2013 Shadows appear in many scenes. Human can easily distinguish shadows from objects, but it is one of the challenges for shadow detection intelligent automated systems.

Interactive removal and ground truth for difficult shadow scenes [PDF]
, 2016 A user-centric method for fast, interactive, robust, and high-quality shadow removal is presented. Our algorithm can perform detection and removal in a range of difficult cases, such as highly textured and colored shadows. To perform detection, an on-the-

Shadow detection with multi-feature fusion and MMSE optimization
Dianzi Jishu Yingyong, 2018 In order to reduce the interference of shadow to detection results of moving targets, a shadow detection method is proposed, which can be made as the post-processing step of motion detection methods.

ANISOTROPIC SCATTERING SHADOW COMPENSATION METHOD FOR REMOTE SENSING IMAGE WITH CONSIDERATION OF TERRAIN [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 With the rapid development of sensor networks and earth observation technology, a large quantity of high resolution remote sensing data is available. However, the influence of shadow has become increasingly greater due to the higher resolution shows more

Sub-shot-noise shadow sensing with quantum correlations [PDF]
, 2017 The quantised nature of the electromagnetic field sets the classical limit to the sensitivity of position measurements. However, techniques based on the properties of quantum states can be exploited to accurately measure the relative displacement of a ...

Adaptive shadow detection using global texture and sampling deduction
IET Computer Vision, 2013 An adaptive shadow detection algorithm is proposed to eliminate interference on object detection from the shadow. The algorithm uses three components in YUV colour space to identify shadow pixels from the candidate foreground.

Detecting moving shadows: algorithms and evaluation [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2003 Moving shadows need careful consideration in the development of robust dynamic scene analysis systems. Moving shadow detection is critical for accurate object detection in video streams since shadow points are often misclassified as object points, causing errors in segmentation and tracking.

A Coarse‐To‐Fine Approach to Detect Shadows in the Chang’E−4 VNIS Hyperspectral Images
Earth and Space Science, 2022 The low value of shadow pixels in the images sensed by the Visible and Near‐infrared Imaging Spectrometers (VNIS) aboard Chang’E−4 Yutu‐2 rover leads to an unrealistic representation of lunar surface reflectance.

Shadows of CPR black holes and tests of the Kerr metric [PDF]
, 2015 We study the shadow of the Cardoso-Pani-Rico (CPR) black hole for different values of the black hole spin $a_*$, the deformation parameters $\epsilon_3^t$ and $\epsilon_3^r$, and the viewing angle $i$.
