DEVICE FOR SEMANTIC CLASSIFICATION AND SEARCH IN ARCHIVES OF DIGITIZED FILM MATERIALS Russian patent published in 2017 - IPC G06F17/30 G06K9/46 G06K9/64 

FIELD: physics.

SUBSTANCE: device for semantic classification and search in archives of digitized film materials contains sequentially connected means for obtaining digitized materials, means for extracting sample frames from digitized film materials, means for extracting feature vectors, segmentation and classification means, index storage means, means for performing information retrieval, a server device and a client device.

EFFECT: improving the accuracy of segmenting films on the stage, increasing the accuracy of the classification of scenes from a predefined list of classes, increasing the speed of the process of extracting semantic signs from the film frames, reducing the additional programming costs with increasing the dimension of the feature vector, reducing the amount of data to store the index to perform information retrieval film fragments by text requests, queries in a structured form and queries on the model, reducing the run time of indexing and increasing the accuracy and sensitivity of information retrieval.
