Abstract
A method and apparatus for retrieving multimedia data using shape information. The multimedia data retrieval apparatus comprises a shape information feature extractor for receiving shape information of a query image and extracting a feature of the received shape information using a shape information descriptor based on eigen vectors of a multilayer covariance matrix, an image feature extractor for extracting a feature of each image data in the same manner as the shape information feature extractor, a multimedia database creator for creating a multimedia database on the basis of the features extracted by the image feature extractor, a similarity comparator for comparing the feature of the query image extracted by the shape information feature extractor with the features of the image data in the multimedia database to calculate similarities therebetween, and a compared result output unit for outputting the results calculated by the similarity comparator. Multimedia data can accurately and rapidly be retrieved by defining and using a shape information descriptor with a consistency against rotation, scaling and translation of the shape information.
