中值滤波,去噪
实验原理:中值滤波器是将领域内像素灰度的中值代替该像素的值,对处理脉冲噪声(椒盐噪声)非常有效。为了对一幅图像上的某个点进行中值滤波处理,必须先将掩模内欲求的像素及其领域的像素值排序,确定出中值,主要功能是使拥有不同灰度的点看起来更接近于它的邻近值。-Median filtering and denoising
Test principle: median filter is to field pixel gray value instead of the pixel v

使用超绿特征分割作物图像。具体来说,首先使用超绿特征将图像灰度化,然后经过中值滤波后,使用Otsu最大类内方差方法将图像二值化,得到分割图像。(The crop image is segmented by super green feature. Specifically, firstly, the image is grayed by Super-Green feature, and then after median filtering, the Otsu maximum intra-cla
