基于微分法的最优算子及其在光测灰度图像处理中的应用

Optimal Operator Based on Differential Method and Its Application in Photometric Grayscale Image Processing

基于边缘的图像特征提取方法是光测图像事后处理的一种重要方法,由于边缘图像具有直观、特征点突出的优点,因而在光测图像事后处理领域有着广泛应用。阐述了微分法边缘检测算子的原理,提出了基于最优算子的光测灰度图像的边缘提取方法,并对其处理效果进行了比对。

The image feature extraction method based on the edge is an important method of photometric image post-processing. Since the edge image has advantages that intuition and prominent feature points,it has been widely used in the field of photometric image post processing. This paper describes the principle of differential edge detection operalor, proposes the edge extraction method of photometric grayscale image based on optimal operator,and compares the treatment effect.
