METHOD AND SYSTEM FOR DETERMINING SYNTHETICALLY MODIFIED FACE IMAGES ON VIDEO Russian patent published in 2022 - IPC G06V10/70 G06T1/40 G06N3/02 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering for determining synthetically altered images of faces on video. Technical result is achieved by a method in which: an image is obtained from a video; identifying images of faces on said image; calculating a vector representation of the geometric characteristics of the detected face images; using frame-by-frame video analysis, calculating the spatial-temporal significance of each face image of each person on said image and a vector representation of the temporal characteristic of the face image; calculating a vector of estimates of the probability of synthetic changes for images of human faces; calculating an overall estimate of the probability of synthetic changes; generating a final assessment of the presence of a synthetic face image change on the video; forming an integral estimate of the presence of a synthetically changed face image on the video at least one final estimate of the model and generating a notification on the presence of the synthetically changed face in the video.

EFFECT: high accuracy and efficiency of detecting synthetic change in images of human faces in video.
