A Survey of Detecting Regions of Interest in a Static Image
静态图像中的感兴趣区域检测技术

The detection of regions of interest (ROI) introduces visual attention mechanism from the human vision to the image analysis. It is significant to improve the efficiency of the existing image analysis system. In this paper, the current technique for detecting ROI in a static image is surveyed. After the background of ROI detection is introduced, the mechanism of visual attention in human visual system is addressed firstly. And then the main algorithms of ROI detection are classified into two categories including bottom up method and top down method. Each of them is discussed in detail respectively. The primary applications of ROI are described afterward. At the end, several research trends of ROI detection are given.
