Large-scale training of shadow detectors with noisily-annotated shadow examples

TFY Vicente, L Hou, CP Yu, M Hoai… - Computer Vision–ECCV …, 2016 - Springer
This paper introduces training of shadow detectors under the large-scale dataset paradigm.
This was previously impossible due to the high cost of precise shadow annotation. Instead …

Leave-one-out kernel optimization for shadow detection and removal

TFY Vicente, M Hoai, D Samaras - IEEE Transactions on …, 2017 - ieeexplore.ieee.org
The objective of this work is to detect shadows in images. We pose this as the problem of
labeling image regions, where each region corresponds to a group of superpixels. To …

Single image shadow detection via complementary mechanism

Y Zhu, X Fu, C Cao, X Wang, Q Sun… - Proceedings of the 30th …, 2022 - dl.acm.org
In this paper, we present a novel shadow detection framework by investigating the mutual
complementary mechanisms contained in this specific task. Our method is based on a key …

L Shen, T Wee Chua, K Leman - Proceedings of the IEEE …, 2015 - openaccess.thecvf.com
We present a novel learning-based framework for shadow detection from a single image.
The local structure of shadow boundaries as well as the global interactions of the shadow …

Fast shadow detection from a single image using a patched convolutional neural network

S Hosseinzadeh, M Shakeri… - 2018 IEEE/RSJ …, 2018 - ieeexplore.ieee.org
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 …

Interactive removal and ground truth for difficult shadow scenes

H Gong, D Cosker - JOSA A, 2016 - opg.optica.org
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 …

Shadow detection via predicting the confidence maps of shadow detection methods

J Liao, Y Liu, G **ng, H Wei, J Chen, S Xu - Proceedings of the 29th ACM …, 2021 - dl.acm.org
Today's mainstream shadow detection methods are manually designed via a case-by-case
approach. Accordingly, these methods may only be able to detect shadows for specific …

Noisy label recovery for shadow detection in unfamiliar domains

TFY Vicente, M Hoai… - Proceedings of the IEEE …, 2016 - openaccess.thecvf.com
Recent shadow detection algorithms have shown initial success on small datasets of images
from specific domains. However, shadow detection on broader image domains is still …

Large scale shadow annotation and detection using lazy annotation and stacked CNNs

L Hou, TFY Vicente, M Hoai… - IEEE Transactions on …, 2019 - ieeexplore.ieee.org
Recent shadow detection algorithms have shown initial success on small datasets of images
from specific domains. However, shadow detection on broader image domains is still …
