【摘要】 根据彩色农业图像的特点,以蔗苗为研究对象对OHTA颜色模型的三分量图进行分割试验,发现I3分量图的分割效果比I1、I2分量图的分割效果要好,更加适合干蔗苗图像分割。在I3分量图中,比较了3种阈值分割方法效果,试验结果发现Ostu法与直方图双峰法分割结果更为接近,比迭代法分割效果更好。更多还原

【Abstract】 According to the characteristics of color agriculture image, with sugarcane seedlings as research objects,segmentation experiment was conducted on three component images in OHTA color model.It was found that the segmentation effect of I3 component image was better than that of I1 and I2,and more suitable for image segmentation of sugar cane seedling.The effects of 3 threshold segmentation methods were compared in I3 component image.The experiment results showed that the segmentation effect of Ostu method was more adjacent to that of histogram bimodal method and better than that of iteration method.更多还原
