Recoding Color Transfer as a Color Homography
Han Gong, Graham D. Finlayson, Robert B. Fisher
Color transfer is an image editing process that adjusts the colors of a picture to match a target picture's color theme. A natural color transfer not only matches the color styles…
Interactive Removal and Ground Truth for Difficult Shadow Scenes
Han Gong, Darren P. Cosker
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: suc…
Color Homography Color Correction
Graham D. Finlayson, Han Gong, Robert B. Fisher
Homographies -- a mathematical formalism for relating image points across different camera viewpoints -- are at the foundations of geometric methods in computer vision and are used…
Interactive Illumination Invariance
Han Gong, Graham Finlayson
Illumination effects cause problems for many computer vision algorithms. We present a user-friendly interactive system for robust illumination-invariant image generation. Compared…
Color Homography
Graham D. Finlayson, Han Gong, Robert B. Fisher
We show the surprising result that colors across a change in viewing condition (changing light color, shading and camera) are related by a homography. Our homography color correcti…
