基于线性变换与多种平滑去噪的爆堆图像增强方法

摘要

介绍了自主设计的"基于灰度线性变换与综合多种平滑去噪"的爆堆图像增强方法.首先根据爆堆图像的灰度分布情况对爆堆图像进行灰度线性变换,使图像中矿岩与背景区别更加明显;然后对爆堆图像用均值滤波、中值滤波、高斯滤波进行综合平滑处理,这样不仅祛除了图像的噪声,而且很好的保留了图像中矿岩的边缘.%This paper designed a blasting lumps image enhancement method on the basis of linear transformation of grayscale and some of smoothness. Firstly, this paper applied the linear transformation of grayscale on blasting lumps according to grayscale scattered of blasting lumps to distinguish between the rocks and background; secondly,this paper smoothed the blasting lumps with Average Filter、 Median Filter and Gauss Filter to removing impurities from image and retained edge of rocks better.
