StyLit: Illumination-Guided Example-Based Stylization of 3D Renderings

StyLit is a new approach to example-based stylization of 3D scenes. It incorporates illumination-specific effects and an improved synthesis algorithm, and it better preserves the visual richness of hand-created style exemplars.

Flow-Guided Warping for Image-Based Shape Manipulation

This paper presents a method that manipulates perceived object shape from a single input image. It produces the illusion of shape sharpening or rounding by modifying orientation patterns, strongly correlated to surface curvature. The warping algorithm produces convincing shape manipulation results for a variety of materials and lighting environments.

Transfiguring Portraits

This system's goal is to let people imagine and explore how they may look in a different country, era, hairstyle, hair color, age, and practically anything else that can be queried in an image search engine.

Band-Sifting Decomposition for Image-Based Material Editing

This paper introduces a set of image filters to alter the perceived properties of the observed materials in a natural way. The filters construct a multi-scale decomposition and modify three axes: scale, sign, and amplitude of the sub-band coefficients. User studies validate the perceptual effects of the filters.
