Abstract
This study presents an autocorrelation function-based program of dynamic image recognition and automatic alarm. Lighting effect analysis, binarization of the dynamic image and other methods were used to enhance the image; a dynamic image autocorrelation function was established to determine the threshold of automatic alarm system; and using Matlab software a simulation experiment was conducted on the autocorrelation function. The experiment showed that the correlation function value is inversely proportional to the amount of change of the video surveillance image; the autocorrelation function value can be used to determine when to trigger the automatic alarm system. This dynamic image recognition program, characterized by strong stability and little impact from the outside, can be used for automatic alarm of monitoring system.
