红外热图像序列中基于人体模型的目标头部定位方法

文章针对红外热图像序列,提出了一种多目标的头部定位方法。该方法检测目标轮廓的上凸点,根据上凸点构造粗略人体模型;利用热函数聚类方法确定投影直方图中峰的个数及位置。最后对上凸点和峰顶点进行综合判断以确定目标个数并定位。实验结果表明,该方法是有效可行的。

Multi People Head Detection in Infrared Thermal Image Sequences Based on Human Shape Model

A novelmethod used to count and locate multi2moving objects in thermal sequences is p roposed in this paper. At first, convex points of objects boundary are detected. Thermal and position information of human shape areused to weight the coefficients of vertical p rojection histogram. Potential function clusteringmethod is used to determinate the number of apex in the histogram and to locate the position of apex. Conves points and apex of histogram are chosen to determinate the number and the position ofmoving object heads. Experimental results show that ourmethodis effective and feasible to count and locate the moving objects in thermal sequences.
