The ID3 algorithm begins with the original set as the root node. On each iteration of the algorithm, it iterates through every unused attribute of the set and calculates the entropy or the information gain of that attribute. It then selects the attribute which has the smallest entropy (or largest information gain) value. The set is then split or partitioned by the selected attribute to produce subsets of th… Witryna摘要：视觉背景提取算法(visual background extraction algorithm,ViBe)建立背景模型时采用首帧图像进行初始化容易引入鬼影,且在光照变化的情况下出现许多误检。针对这些问题,提出一种改进的视觉背景提取算法(Modified ViBe,MViBe)。用邻域像素具有空间一致性的性质对可疑的鬼影像素做出进一步判断,实现对 ...
