We propose a simple yet effective reflection-free cue for robust reflection removal from a pair
of flash and ambient (no-flash) images. The reflection-free cue exploits a flash-only image …

We present a method to automatically detect shadows in a fast and accurate manner by
taking advantage of the inherent sensitivity of digital camera sensors to the near-infrared …

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 …

We propose a simple yet effective reflection-free cue for robust reflection removal from a pair
of flash and ambient (no-flash) images. The reflection-free cue exploits a flash-only image …

In this paper we present a surprisingly simple yet powerful method for detecting illumination—
determining which pixels are lit by different lights—in images. Our method is based on the …

This paper presents a novel user-aided method for texture-preserving shadow removal from
single images requiring simple user input. Compared with the state-of-the-art, our algorithm …

Shadows, which are cast by clouds, trees, and buildings, degrade the accuracy of many
tasks in remote sensing, such as image classification, change detection, object recognition …

Shadows, due to their prevalence in natural images, are a long studied phenomenon in
digital photography and computer vision. Indeed, their presence can be a hindrance for a …

In this paper, we present a method to estimate ambient illuminants using no-flash/flash
image pairs. Accurate estimation of the ambient illuminant is useful for imaging applications …

Shadows bedevil multimedia applications, eg seeing into shadow regions in surveillance
video. Model-based and non-model based, statistical methods, spatial, temporal, and …
