为解决传统水稻冠层图像分割算法性能在很大程度上依赖于训练数据集的质量，且分割效果易受田间多变光照强
度影响，导致水稻生产参数估计精度不高等问题，提出一种基于Lab 颜色空间的非监督贝叶斯方法
To solve the problem of traditional rice canopy image segmentation algorithms, the performance largely depends on the quality of the training dataset, and the segmentation effect is easily affected by the varying intensity of field lighting
A unsupervised Bayesian method based on Lab color space is proposed to address the issue of low estimation accuracy of rice production parameters due to the influence of degree (2023-05-29, Others, 2825KB, 下载0次)
