摘 要: 提出一种新的基于颜色模式的道路背景提取及更新算法。通过计算一段时间内视频图像的颜色模式来提取背景图像。为了避免了环境光的扰动对背景图像的影响,引入量化后的颜色模式的计算公式,增强了算法的鲁棒性。通过计算当前图像和背景图像以及上一帧图像的差分,得到不变区域更新背景。实验表明,本算法对光线变化鲁棒性高、速度快、更新效果好。 A new algorithm of background extraction and updating based on mode of color is proposed. The mode of color values in the video streams is calculated to extract background image. To avoid the effect of disturbances in lighting, a function to calculate the mode of quantized color value is introduced; the algorithm robust is enhanced. The image difference between current frames and background is calculated, the unchanged part of background is got from the two difference image amalgamation. The background is u...
