Embodiment 1
[0048] Based on the high reliability of the video stream, the present invention detects the psychophysiological parameter algorithm by measuring each parameter of the psychophysiological characteristics of the subject to generate a statistical analysis application device.
[0049] In addition, the present invention uses the acquired video stream to measure the high-reliability measurement value of each parameter of the psychophysiological characteristics in the case of moving or gathering in the crowd, and expands the target image through the zoom-in function provided by the traditional camera, and improves the improvement of face recognition and analysis. The energy generated by the body muscles and the correlation change algorithm of the pixel points are used for real-time dynamic analysis of the high-reliability psychophysiological analysis statistical algorithm.

Embodiment 2
[0081] See Figure 4 , Image 6 The difference from the above-mentioned embodiment is that the present invention is a method for detecting high-risk persons with changes in human appearance to determine human emotions, including the following steps:
[0082] Step 1): Image information collection S1;
[0083] Step 2): image information preprocessing S2;
[0084] Step 3): Image information processing S3;
[0085] Step 4): Output the information result S4.
[0086] The image information collection includes video information collection.
[0087] The image processing includes processing video information to generate a biological signal containing a degree of danger;
[0088] According to the vibration frequency and / or amplitude of the biological signal, the degree of danger of the tested person is obtained.
[0089] The degree of danger of the tested person is based on the following algorithm:
[0090]
[0091] Maximum frequency of FM-frequency distribution density histogram
[0092] Fi-1 second...
