  1. Draw the gait outline of people subtraction we received, and calculate the outline centroid. then we obtain n dots at the outline, calculating the normalized distances of the dots we obtained with the centroid, and the distances constitute the input vector

    將步態檢測得到的人的剪影提取輪廓,計算輪廓質心。取得輪廓上若干點,把提取的邊界點與質心點的歸一化距離作為輸入向量。
  2. Performs vector subtraction on the two specified

    對兩個指定的
  3. The background subtraction method is used to retrieve the foreground, and the mixture gaussian model is used to model the background, during the modeling, the improved k - means algorithms is applied to improve the speed of background modeling ; 2. in the process of the background updating, the updating algorithms based on statistical average is used to update the background, compared to the traditional background updating methods, it improves the speed of the background updating ; 3. to solve the problem that the detection method based on gaussian shadow model detects the shadow inaccurately under some situations, a novel algorithm based on the body color vector matching is presented to detect and eliminate the shadow

    本文在總結和分析了國內外相關研究工作的基礎上,針對運動物體檢測與提取中如何檢測與提取前景區域以及如何檢測與去除陰影的問題開展研究,其主要研究內容和成果如下: 1 .採用背景減除法提取前景區域,利用混合高斯模型進行背景建模,建模過程中,引入了改進的k -均值演算法,加快了背景建模的速度,提高了背景建模的質量; 2 .在背景更新的過程中,採用了基於統計平均的更新演算法,相對于傳統的背景更新方法,提高了背景更新的速度; 3 .針對運動物體陰影檢測與去除中,基於高斯陰影模型的陰影檢測方法在某些情況下對陰影檢測不準確的問題,提出了一種基於體色向量匹配的陰影檢測與去除演算法。
