  • Method of image segmentation for object-based image retrieval
    Publication number: 20030108237
    Abstract: This paper provides a new image segmentation algorithm for object-based image retrieval. The system partitions multi-dimensional images into disjoint regions of coherent color and texture. In order to distinguish the object contour lines from texture edge, the description length of the line is used as discriminating criteria. Visual attribute values are assigned to each region.

  • Method and system for similarity-based image classification
    Patent number: 6269358
    Abstract: A method and apparatus for classifying and querying a database of images, in which the images in the database are classified using primary objects as a clustering center. A query interface is presented to the user allowing the user to use the primary objects to formulate queries to be applied to the classified database of images.

  • Method and system for image querying using region based and boundary based image matching
    Patent number: 6240423
    Abstract: A method and apparatus for querying a database of images, in which the results of the query are based upon a combination of region based image matching and boundary based image matching. Additionally similarity calculations are made between individual results of the query so that the results may be clustered based upon similarity.

  • Image index production method and image index production system for image storage and management system
    Patent number: 5781899
    Abstract: The similarity between zones which consist of one or plural pixels in an original image is measured, the similarity between the measured zones and the threshold of the similarity for integrating the zones consisting of one or plural pixels in the original image are received, and the original image is divided to make the similarity between respective zones lower than the threshold. The size of the zone-divided image for the image index is determined to make the number of total zones of the current divided image equal to the number of zones to be finally divided as an index. Attribute information on the zones of the zone-divided image is calculated to produce an index.
