The algorithm begins with pre-segmentation at a low resolution level and transmits the result to optimally segmentalize on a higher resolution scale 在粗尺度上采用基于区域的高斯噪声模型分析图像,并和测地线模型相结合实现预分割,预分割结果表明了组合模型能自动和精确地提取边界。
The content of searching for urban temporal distance mostly includes holistic temporal shape, temporal structure, temporal position and drawing of temporal map and so on . the premise is to segmentalize city area into time units and calculate temporal distance 城市时间距离研究的主要内容包括城市的整体时间形态、城市的时间结构组成、城市的时间区位分析以及时间地图的制作等等。
