Indexing Flower Patent Images Using Domain Knowledge, Madirakshi Das, R. Manmatha, Edward M. Riseman
R. Manmatha
A new approach to indexing a specialized database by utilizing the color and spatial domain knowledge available for the database is described. This approach is illustrated by using it to provide a solution to the problem of indexing images of flowers for searching a flower patents database by color. The flower region is isolated from the background by using an automatic iterative segmentation algorithm with domain knowledge-driven feedback. The color of the flower is defined by the color names present in the flower region and their relative proportions. The database can be queried by example and by color names. The …

Multi-Modal Retrieval Of Trademark Images Using Global Similarity, S Ravela, R. Manmatha
R. Manmatha
In this paper a system for multi-modal retrieval of trademark images is presented. Images are characterized and retrieved using associated text and visual appearance. A user initiates retrieval for similar trademarks by typing a text query. Subsequent searches can be performed by visual appearance or using both appearance and text information. Textual information associated with trademarks is searched using the INQUERY search engine. Images are searched visually using a method for global image similarity by appearance developed in this paper. Images are filtered with Gaussian derivatives and geometric features are computed from the filtered images. The geometric features used here …
