Abstract

The embodiment of the invention discloses an eye behavior detection method and device and a storage medium. The method includes: sliding a time window on a video frame of the target video, obtaining an image sequence of the target object, wherein the image sequence comprises a plurality of images with a time sequence relationship; carrying out feature extraction on the eye region of each image; obtaining initial feature information of a plurality of eye regions with a time sequence relationship; according to a time sequence relationship of the eye region, fusing the initial feature informationand the difference feature information of the eye region; obtaining a plurality of pieces of fusion depth feature information with a time sequence relationship; according to a plurality of pieces offusion depth feature information with a time sequence relationship, obtaining probability values of eye behaviors of each image as preset eye behaviors, wherein the g probability values have a time sequence relationship; generating a probability curve coordinate system according to the plurality of probability values with the time sequence relationship, and determining whether a target object hasthe preset eye behaviors or not according to the probability curve coordinate system. According to the invention, the accuracy of eye behavior detection can be improved.

Description

Technical field [0001] The present invention relates to the technical field of behavior detection, in particular to an eye behavior detection method, device and storage medium. Background technique [0002] Blink detection is a widely used technology in real life, and blink detection has been used in many application scenarios. Blink detection is an important part of the motion detection program. Living body detection is a very important part of the face core system, and it has been used in many application scenarios. Among them, the motion live body is one of the most widely used solutions for live body detection, and the blink detection is the top priority of the motion live body solution. [0003] In the existing blink detection methods, blink detection is performed based on the location features of feature points. The main technical principle is to extract manual features (EAR features, etc.) by locating the positions of key points of the human eye. Afterwards, the extracted...
