摘要
描述了一个多目标检测及特征提取的新方法.它是在边界跟踪过程中,自动确定一个包含目标区域的虚拟矩形窗口,利用差分技术提取窗口内的目标区域的同时;将其抹去.当处理完整幅切片图象时,能获得切片图象上存在的目标个数及每个目标区域相应的特征(如面积、周长等).
This paper presents a new method for detecting target's regions and extracting their features form slice images. It automatically determines a virtual rectangular window including the targets region in the boundary following process, and the region is elimenated while extracted by difference technique. Number of regions, features of each region (such as area, perimeter etc) are obtained after processed whole image.
