Abstract:

Based on the study of gray histograms of video sequences,  a new algorithm named the superposition principle of gray histograms and a corresponding approximate superposition formula is introduced, which can well describe the gray histogram of many video scenes formed by background and moving objects and afford an effective method of detecting moving objects in a dynamic background in the future. Experiments show that the superposition principle formula works well in such scenes as uniform background, and the principle can describe various combinations of scenes formed by the background and multiple objects, and detect moving objects in a dynamic background in future video analysis. It is helpful in video analysis.

Key words: gray histogram; superposition principle; object detection; dynamic background
