Shadow detection with multi-feature fusion and MMSE optimization

open access: yesDianzi 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.

Adaptive shadow detection using global texture and sampling deduction

open access: yesIET 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]

open access: yesIEEE 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.

ANISOTROPIC SCATTERING SHADOW COMPENSATION METHOD FOR REMOTE SENSING IMAGE WITH CONSIDERATION OF TERRAIN [PDF]

open access: yesThe 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

Illumination invariance and shadow compensation via spectro-polarimetry technique [PDF]

open access: yes, 2013
A major problem for obtaining target reflectance via hyperspectral imaging systems is the presence of illumination and shadow effects. These factors are common artefacts, especially when dealing with a hyperspectral imaging system that has sensors in the

A Coarse‐To‐Fine Approach to Detect Shadows in the Chang’E−4 VNIS Hyperspectral Images

open access: yesEarth 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.

DARCLOS: a cloud shadow detection algorithm for TROPOMI [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
Cloud shadows are observed by the TROPOMI satellite instrument as a result of its high spatial resolution compared to its predecessor instruments. These shadows contaminate TROPOMI's air quality measurements, because shadows are generally not taken into ...

An Adaptive Snake Based Shadow Segmentation for Robust Driver Fatigue Detection: A 3D Facial Feature Based Photometric Stereo Perspective

open access: yesIEEE Access, 2023
Fatigue detection has many applications, one of them is intelligent transportation for accident prevention. It is challenging to detect driver fatigue adopting photometric stereo and 3D fatigue-related facial action unit identification.

Moving shadow detection and removal – a wavelet transform based approach

open access: yesIET Computer Vision, 2014
Shadow detection and removal is an important problem in computer vision. The real challenge in moving shadow detection and removal is to classify moving shadow points which are many times misclassified as moving object points in a video sequences ...
