METHOD OF IDENTIFYING PERSON IN VIDEO FRAME STREAM Russian patent published in 2024 - IPC G06V10/70 

FIELD: physics.

SUBSTANCE: invention relates to image recognition. Technical result is achieved by the fact that the figures of people are detected on the current frame, the detected figure is highlighted by the corresponding bounding frame; performing bounding box positions prediction using Kalman filter; calculating the similarity of each predicted bounding box using a floristic commonality coefficient; generating a vector representation of the image enclosed in a bounding box for the figure; performing in the database matching of the generated vector representation of the figure by the nearest neighbour method; selecting a bounding box for the head within the detected bounding box for the figure; generating a vector representation of the image enclosed in a bounding box for the head; performing in the database matching of the generated head vector representation by the nearest neighbour method; and identifying a person by means of a weighted sum of results of matching by figure and by head.

EFFECT: high accuracy of identifying a person in a stream of video frames when there is overlapping of figures and heads.
