PPT-Image Matching and Retrieval by Repetitive Patterns

Petr Doubek Jiri Matas Michal Perdoch and Ondrej Chum Center for Machine Perception Czech Technical University in Prague Czech Republic Detection of repetitive patterns in images is a wellestablished computer vision problem However the detected patterns are rarely used in any application A method for representing a lattice or line pattern by shiftinvariant descriptor of the repeating tile is presented The descriptor respects the inherent shift ambiguity of the tile definition and is robust to viewpoint change Repetitive structure matching is demonstrated in a retrieval experiment where images of buildings are retrieved solely by repetitive patterns.

Model is an idealization or abstraction of an actual process. in this case, process is matching of documents with queries, i.e., retrieval. Image Processing . Pier Luigi .
