Shadow-Based Vehicle Detection in Urban Traffic [PDF]
Sensors, 2017 Vehicle detection is a fundamental task in Forward Collision Avoiding Systems (FACS). Generally, vision-based vehicle detection methods consist of two stages: hypotheses generation and hypotheses verification. In this paper, we focus on the former, presenting a feature-based method for on-road vehicle detection in urban traffic.

ShadowDeNet: A Moving Target Shadow Detection Network for Video SAR
Remote Sensing, 2022 Most existing SAR moving target shadow detectors not only tend to generate missed detections because of their limited feature extraction capacity among complex scenes, but also tend to bring about numerous perishing false alarms due to their poor ...

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

Fast Shadow Detection from a Single Image Using a Patched Convolutional Neural Network
, 2018 In recent years, various shadow detection methods from a single image have been proposed and used in vision systems; however, most of them are not appropriate for the robotic applications due to the expensive time complexity. This paper introduces a fast

ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2014 Motion perception is an amazing innate ability of the creatures on the planet. This adroitness entails a functional advantage that enables species to compete better in the wild. The motion perception ability is usually employed at different levels, allowing from the simplest interaction with the ’physis’ up to the most transcendental survival tasks ...

Effective moving cast shadow detection for monocular color image sequences [PDF]
, 2001 For an accurate scene analysis in monocular image sequences, a robust segmentation of a moving object from the static background is generally required. However, the existence of moving cast shadow may lead to an inaccurate object segmentation, and as a ...

Moving shadow detection and removal – a wavelet transform based approach
IET 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 ...
