| 摘 要： | 图像的显著性分析是计算机视觉的一个重要研究方向。鉴于现有方法主要集中于对单幅图片进行显著分析,缺乏连续的、摄像头可动的显著图的深入研究。本文受到人类视觉系统的启发,设计了全方位三维显著空间系统。该系统使用提供摄像头方向信息的球形摄像机,将每帧图片的显著区域映射到显著空间中,并对映射结果进行简明有效的显示。本文详细介绍了该系统的组成框架和显著空间映射方法。通过测试验证,该系统具有良好的实时性,并成功实现了目标设计功能。

| Abstract: | Saliency map generating is an important research direction in computer vision. But most of the existing technologies focus on single image processing,and are lack of research on continuous video saliency analysis using movable camera. Inspired by human visual system,this paper presents an omnidirectional 3-dimensional saliency space system. This system adopts a sphere camera,which could provide camera direction information,and maps saliency regions from single frame to saliency space. The mapping results are shown in the screen in a simple and effective way. This paper introduces the composition of the system and details space mapping algorithm. Through the test,the system successfully meets the target design function and has good real-time performance. |
