When capturing an iris image under unconstrained conditions and without user cooperation, the image quality can be highly degraded by poor focus, off-angle view, motion blur, specular reflection (SR), and other artifacts. The noisy iris images in

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
