Gabor texture in active appearance models

In computer vision applications, Active Appearance Models (AAMs) is usually used to model the shape and the gray-level appearance of an object of interest using statistical methods, such as PCA. However, intensity values used in standard AAMs cannot provide enough information for image alignment. In this paper, we firstly propose to utilize Gabor filters to represent the image texture. The bene...

Statistical Models of Mammographic Texture and Appearance

Breast cancer is the most common cancer in women. Many countries—including the UK—offer asymptomatic screening for the disease. The interpretation of mammograms is a visual task and is subject to human error. Computer-aided image interpretation has been proposed as a way of helping radiologists perform this difficult task. Shape and texture features are typically classified into true or false d...

Texture for Appearance Models in Computer Vision and Graphics

Appearance modeling is fundamental to the goals of computer vision and computer graphics. Traditionally, appearance was modeled with simple shading models (e.g. Lambertian or specular) applied to known or estimated surface geometry. However, real world surfaces such as hair, skin, fur, gravel, scratched or weathered surfaces, are difficult to model with this approach for a variety of reasons. I...

Contrast Negation and Texture Synthesis Differentially Disrupt Natural Texture Appearance

Natural textures have characteristic image statistics that make them discriminable from unnatural textures. For example, both contrast negation and texture synthesis alter the appearance of natural textures even though each manipulation preserves some features while disrupting others. Here, we examined the extent to which contrast negation and texture synthesis each introduce or remove critical...

Wedgelet Enhanced Appearance Model

Statistical region-based segmentation methods such as the Active Appearance Model (AAM) are used for establishing dense correspondences in images based on learning the variation in shape and pixel intensities in a training set. For low resolution 2D images this can be done reliably at close to real-time speeds. However, as resolution increases this becomes infeasible due to excessive storage an...
