Simple Primary Colour Editing for Consumer Product Images
Han Gong, Luwen Yu, Stephen Westland
We present a simple primary colour editing method for consumer product images. We show that by using colour correction and colour blending, we can automate the pain-staking colour…
Convolutional Mean: A Simple Convolutional Neural Network for Illuminant Estimation
Han Gong
We present Convolutional Mean (CM) - a simple and fast convolutional neural network for illuminant estimation. Our proposed method only requires a small neural network model (1.1K…
Concise Radiometric Calibration Using The Power of Ranking
Han Gong, Graham D. Finlayson, Maryam M. Darrodi
Compared with raw images, the more common JPEG images are less useful for machine vision algorithms and professional photographers because JPEG-sRGB does not preserve a linear rela…
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…
