摘要
背景提取是运动目标检测中重要而基础的一个环节。分析了一般静态背景提取算法的原理和缺陷,提出了一种新颖的基于改进K-均值聚类算法的背景提取方法,给出了动态三元组(DTDG)的概念,并且对每个像素用3个动态三元组进行建模,实现了原始背景的提取。实验验证了所提方案的有效性。
Background generation is an important and basic step in moving objects detection. The analysis of the principle and imper- fection of general methods for stationary background generation is tried. A novel approach to background generation based on modified K-means is proposed. A concept-dynamic-three-dimension-group (DTDG) and pixel modelled using three dynamic-three-dimension- groups are issued out. The method gets the generation of background. The experiment demonstrate the effectiveness of the method.
