Method for processing a digital gray value image so that a reduced image noise and simultaneously a higher image sharpness is achieved
Abstract:
A method for processing a digital gray value image includes the steps of: generating a binary edge image from the gray value image so that edges present in the gray value image are determined as line areas around the edges; applying a sharpness algorithm in the gray value image within regions which correspond to the line areas; and, carrying out a smoothing process in the gray value image within regions which lie outside of the line areas so that an additional smoothed, sharpened gray value image is generated.
Abstract(Chinese):

一种处理数字灰度值图像的方法包括以下步骤：从灰度图像生成二进制边缘图像，使得存在于灰度图像中的边缘被确定为边缘周围的线区域; 在与行区域对应的区域内的灰度图像中应用锐度算法; 并且在位于行区域之外的区域内的灰度值图像中进行平滑处理，从而生成附加的平滑化，锐化的灰度值图像。
