基于光波迭加原理的相对深度和边缘检测算法
|
摘要
基于光波迭加原理导出了一种新的图像相对深度和边缘检测算法.新算法根据光波的迭加和衰减特性,通过对像素的迭加计算和对参数β的调整使得该算法实现两种功能:相对深度检测和边缘提取.实验表明,该方法能够较好的区分出不同距离的景物,并且能较好地提取图像的边缘.
This paper proposes a relative depth and edge detection algorithm based on superposition of light. According to superposition and attenuation of light, the algorithm restores image pixels to detect the relative depth of pixels and image edge. Experiments on images indicate that the new detector can not only distinguish between objects near and far, but also can get a good edge map.
