Colorful Diffuse Intrinsic Image Decomposition in the Wild
Best Paper Award Honorable Mention
Patent pending

We present a method that can represent in-the-wild photographs in terms of albedo, diffuse shading, and non-diffuse residual components. Our shading layer reflects the colorful nature of multiple illuminants and secondary reflections in the scene, while our residual layer models the specularities and visible light sources.
Abstract
Intrinsic image decomposition aims to separate the surface reflectance and the effects from the illumination given a single photograph. Due to the complexity of the problem, most prior works assume a single-color illumination and a Lambertian world, which limits their use in illumination-aware image editing applications. In this work, we separate an input image into its diffuse albedo, colorful diffuse shading, and specular residual components. We arrive at our result by gradually removing first the single-color illumination and then the Lambertian-world assumptions. We show that by dividing the problem into easier sub-problems, in-the-wild colorful diffuse shading estimation can be achieved despite the limited ground-truth datasets. Our extended intrinsic model enables illumination-aware analysis of photographs and can be used for image editing applications such as specularity removal and per-pixel white balancing.
