Texture is an important visual attribute for both human perception and image analysis. It provides useful information for object and scene understanding. However, unlike other computer vision techniques that focus on object shape, texture analysis provides important clues for material understanding. The focus of this thesis is on material identification from texture images. This is a challenging problem that has not received adequate attention. It is important for a variety of applications including surveillance and security, environmental monitoring, agriculture and forestry, health, product design, and sense substitution.

520 $a Texture is an important visual attribute for both human perception and image analysis. It provides useful information for object and scene understanding. However, unlike other computer vision techniques that focus on object shape, texture analysis provides important clues for material understanding. The focus of this thesis is on material identification from texture images. This is a challenging problem that has not received adequate attention. It is important for a variety of applications including surveillance and security, environmental monitoring, agriculture and forestry, health, product design, and sense substitution.
520 $a The proposed techniques account for dramatic changes in texture appearance due to variations in illumination and viewing conditions. The key elements of the proposed approach are (1) an adaptation of the Visual Similarity by Progressive Grouping (ViSiProG) procedure for identifying clusters of visually similar textures (2) the characterization of each material with a small set of exemplars; (3) the use of machine learning techniques for training of Structural Texture Similarity Metrics (STSIMs) to agree with human perception based on clusters from ViSiProG, and as a result, to be able to separate the textures according to the material they correspond to.
520 $a Human perception has long been considered as a benchmark for computer vision and image analysis applications. However, current human-based annotation methods mostly deal with application outputs. Instead, we explore the possibilities of capturing human perception at a lower level (visual similarity of images), and utilize a learning framework for metric adaptation.
520 $a We demonstrate the effectiveness of the proposed techniques using "CUReT," a fully labeled database of real-world surfaces, viewed under different illuminations and viewing angles at a fixed distance. However, the proposed approaches can be applied to different domains, especially when semantic labeling is not available, for example in an unlabeled database of satellite images, which offers a much wider range of materials, illuminations, and viewing angles, and an unlabeled database of building fronts obtained from "Google Earth Street View."
