Abstract
A video detection device includes a video acquisition interface, a video recognition interface, and a tilt angle estimation interface. The video acquisition interface acquires a video of the face of an imaging subject. The video recognition interface recognizes the left and right eyes from the video acquired by the video acquisition interface. The tilt angle estimation interface estimates a tilt angle with respect to the horizontal based on the position of the left and right eyes recognized by the video recognition interface.
Claims7
A video detection device comprising:
- a video acquisition interface that acquires a video in which the face of an imaging subject is captured;
- a video recognition interface that recognizes the left and right eyes in the video acquired by the video acquisition interface;
- and
- a tilt angle estimation interface that estimates a tilt angle with respect to the horizontal based on the position of the left and right eyes recognized by the video recognition interface, wherein
- the tilt angle estimation interface estimates the tilt angle by practicing at least one of obtaining a difference between video frames and performing averaging between the video frames.
A video detection device, comprising:
- a video acquisition interface that acquires a video in which the face of an imaging subject is captured;
- a video recognition interface that recognizes the left and right eyes in the video acquired by the video acquisition interface;
- a tilt angle estimation interface that estimates a tilt angle with respect to the horizontal based on the position of the left and right eyes recognized by the video recognition interface;
- and
