A common method for real-time segmentation of moving regions in image sequences involves “background subtraction,” or thresholding the error between an estimate of the image without moving objects and the current image. The numerous approache

自回归模型是数学预测计算中很常用的模型，用途广泛，在工程实际背景或者数学建模竞赛中都会经常用到-Since the regression model is very commonly used mathematical calculations to predict the model, widely used in engineering or mathematical modeling contest in the background are often used
