摘要
简要介绍图像的亮度矩以及在保持图像亮度矩不变的条件下对图像进行两级阈值分割的方法 ,并对这种方法得到的方程组采用最小二乘法进行求解 ,以减小噪声干扰 。
This article introduces an intensity moment of images and recommends a method used for the bi level thresholding of images on the condition of keeping the intensity moment invariable. The resulting equations of the method are solved by least square method in order to reduce the interfere of the noise and a precise threshold is yielded.
