Cognition curve scan method based on video

Abstract

The invention provides a cognition curve scan method based on a video. The method includes the following steps: step S1, acquiring video data and cognition value sequential data corresponding to the video data; step S2, dividing the video data through timer shaft nodes according to the duration of the acquired video data, and acquiring a cognition values in the cognition value sequential data corresponding to each timer shaft node; step S3, defining a coordinate axis, regarding the timer shaft nodes of the duration of the video data as an X-axis, and regarding the cognition values in cognition value sequential data as a Y-axis; step S4, defining the cognition value corresponding to each timer shaft node in a coordinate plane in the method of hidden points in advance; step S5, starting and playing the video, and sequentially displaying the points hidden in the coordinate plane in advance according to a duration sequence of the timer shaft nodes with the timer shaft nodes of the duration of the video data as a unit to achieve a scan effect.

Description

technical field [0001] The invention relates to the scanning field, in particular to a video-based cognitive curve scanning method. Background technique [0002] Pupil responses include pupil constriction and dilation. Pupil dilation and constriction are controlled by the autonomic nervous system. Current research has found that pupil size changes are also closely related to the individual's cognitive and emotional information processing. expansion. The pupil is actually responsible for controlling the amount of light entering the eyes. When seeing a pleasant stimulus, the autonomic nervous system will cause the pupil to dilate, allowing more visual information of good things to enter the brain, forming a positive stimulus, thereby triggering a pleasant feeling. Experts who focus on "microexpressions" also often use the fact that pupil dilation is not subject to individual subjective control to detect lies in others. [0003] With the development of commerce, the competi...

Problems solved by technology

[0004] It is not difficult to see that the amount of information brought by the change of the pupil is huge, which is very good for people's judgment and analysis of things, but in real life, there is no good way to analyze the change of the pupil. How to reflect changes in people's senses or psychology, and then it is impossible to analyze the attractiveness of a certain thing or a certain video screen to people, etc.
