红外视频图像中的人体目标检测方法

人体目标检测是很多机器视觉应用的难点,如智能视频监控和车辆辅助驾驶,基于可见光图像的方法很难解决复杂背景和目标区域的分离问题,因此,越来越多的研究转向利用红外图像进行检测。提出了一种红外视频图像中的人体目标检测方法,该方法首先利用红外图像中像素值近似呈现单模态分布的特点,对高亮像素进行检测,然后采用灰度直方图和投影直方图相结合的2D直方图特征对目标进行检测。实验结果表明:该方法具有较高的检测率,但误报率也较高,其原因在于负样本的数量和代表性不足,因此,改进空间很大。

Human detection method in infrared video images

Human detection in images is a challenging problem in the applications of machine vision, such as intelligent video surveillance and vehicle assistance driving. Because visible -image-based methods have difficulty in extracting moving objects from complex backgrounds, more research interests on human detection have been addressed in infrared video images. In this paper, a new method for detecting human in infrared video images was proposed. Due to the pixel values in infrared images could be approximately m...
