Latest Patents

One of DeFazio's latest patents is a "System for efficient content-based retrieval of images." This system creates and utilizes a visual image index for effective visual image retrieval. The visual image index employs multi-level filtering to minimize the processing and storage required to identify visual images that share similar characteristics with a query image. Information about each visual image is stored in an image signature, which contains data about essential visual primitives such as global color, local color, texture, and structure. The signature is stored in a database table alongside the image or a link to it. Visual image retrieval is conducted by searching for signatures in the database that are similar to the signature of the query image. The multi-level filtering process reduces the number of candidate images before a comprehensive comparison is made on the filtered set of candidate image signatures.

Another notable patent is for a "Database having an integrated transformation engine using pickling and unpickling of data." This method and system facilitate the handling of data items within a database system that are associated with unsupported data types. The data types are registered with the database system by storing metadata that indicates their structure, physical layout, and applicable constraints. The database system utilizes this information to access individual elements of data items and validates them based on the constraints provided. This allows for the storage of data items associated with various data types in the same table, enabling applications to access these items through a transformation view that converts them from their native format to a format expected by the applications.
