Finding Symmetry in Intensity Images TITLE2

The goal of image retrieval is to retrieve images OsimilarO to a given query image by comparing the query and database using visual attributes like color, texture and appearance. In this paper, we discuss how to characterize appearance and use it for image retrieval. Visual appearance is represented by the outputs of a set of Gaussian derivative filters applied to an image. These outputs are computed off-line and stored in a database. A query is created by outlining portions of the query image deemed useful for retrieval by the user (this may be changed interactively depending on e results). The query is also filtered with Gaussian derivatives and these outputs are compared with those from the database. The images in
