摘要
该文分析了顺序形态学和普通形态学运算的特点,在此基础上研究了基于顺序形态运算的边缘检测,通过对原始图像采用不同百分位值和结构元素的顺序形态变换,可以选择不同阈值和图像中目标信号分布范围,结合Canny检测算子能有效检测灰度接近背景的目标区域的边界。
In this paper, order and normal morphology transformation is discussed. Edge detection based on morphology is presented. Different threshold is detected by morphology operator, and scope of signal area is also obtained by order morphology with different size of element structure and value of percent. Low intensity signal edge is detected effectively by canny operator following morphology transform.
