Exploring features in a Bayesian framework for material recognition
We are interested in identifying the material category, e.g. glass, metal, fabric, plastic or wood, from a single image of a surface. Unlike other visual recognition tasks in computer vision, it isExpand

Image statistics and the perception of surface qualities
The world is full of surfaces, and by looking at them we can judge their material qualities. Properties such as colour or glossiness can help us decide whether a pancake is cooked, or a patch ofExpand

Compressing and companding high dynamic range images with subband architectures
High dynamic range (HDR) imaging is an area of increasing importance, but most display devices still have limited dynamic range (LDR). Various techniques have been proposed for compressing theExpand

Recognizing Materials Using Perceptually Inspired Features
Our world consists not only of objects and scenes but also of materials of various kinds. Being able to recognize the materials that surround us (e.g., plastic, glass, concrete) is important forExpand

Accuracy and speed of material categorization in real-world images.
It is easy to visually distinguish a ceramic knife from one made of steel, a leather jacket from one made of denim, and a plush toy from one made of plastic. Most studies of material appearance haveExpand

The Perception of Lighting Inconsistencies in Composite Outdoor Scenes
It is known that humans can be insensitive to large changes in illumination. For example, if an object of interest is extracted from one digital photograph and inserted into another, we do not alwaysExpand

Image statistics for surface reflectance perception.
Human observers can distinguish the albedo of real-world surfaces even when the surfaces are viewed in isolation, contrary to the Gelb effect. We sought to measure this ability and to understand theExpand
