Abstract
The invention discloses a method for video moving object detection based on the statistical characteristics of image pixels. It can better adapt to changes in environmental lighting, and meanwhile have a better tolerance for dynamic backgrounds in the environment. The present invention first classifies pixels according to the different brightness change trends shown by the reflective characteristics of objects in the image, and then establishes reference points in each category according to the characteristics of each pixel point, and finally for dynamic background points in complex situations etc., based on the characteristics of its brightness value switching back and forth between different objects, using the idea of the Gaussian mixture model to analyze the change category to which the points belong. The invention does not need to update the model in real time, with rapid detection, and good adaptability to complex scenes.
