Abstract: A method for processing video data involves receiving data from a series of images and analyzing the data to identify geometric forms. The forms are stored as metadata of a first data level and are linked by time stamps to the images in which the forms were identified. The metadata from an image and the previous image are compared, and delta metadata is generated from the difference. Delta metadata is also marked with time stamps. Metadata and delta metadata are analyzed, and objects are extracted from the geometric forms. The objects are stored as time-stamped metadata and delta metadata of a second data level. The process is repeated for higher data levels. A user inputs a database query to identify from among the stored input images that particular image sequence in which the extracted object is recorded. Queries started at higher data levels are quicker but less accurate.
