| 摘 要： | 以监控系统为研究背景,充分利用场景中视听媒体间存在的天然时空相关性,将视觉信息和听觉信息有效地融合从而实现对目标的快速跟踪.利用机器视觉相关理论提取视觉运动特征,利用计算听觉场景分析技术抽取音频场景特征,建立视听信息特征级融合模型并进行联合场景事件判断.仿真结果表明,应用视听信息融合对目标进行跟踪,预测误差小于单独基于视觉的目标跟踪,同时听觉信息的引入有助于克服图像噪声.

| Abstract: | Taking surveillance system as investigation background,a fast target tracking was realized by means of full utilization of natural spatial-temporal correlation of audio and video media with each other in scene and effective information fusion of these two media.Visual features of motion were extracted by using the machine vision-related theory,and the technique of computational auditory scene analysis was used to extract the features of audio scene,so that a model of audio-video information fusion at featur... |
