Nonparametric Bayesian Texture Learning and Synthesis Leo Zhu and Bill Freeman Joint work with Chen and Torralba

Outline Task: Texture Learning and Synthesis Approach: Nonparametric Bayesian Learning and Image Quilting Texture Model: Hierarchical Dirichlet Process + 2D-HMM

Texture Analysis and Synthesis Input Texture Texture Synthesis Texture Analysis

Flow Chart

Image Features: Filter Responses

Graphical Model: HDP + 2D-HMM

Learning

Result I: Regular Texture

Result II: Stochastic Texture

Result III: Mixture Texture (natural)

Applications: Aerial Image Analysis Automatic terrain categorization and annotation Fast satellite map synthesis Satellite map compression Fake/random map generation
