但是,对于计算机要解释一张图片的内容是很难的,因为计算机看到的图片是一个大的数字矩阵,它对图像传递的思想、知识和意义一无所知。 为了理解图像的内容,我们必须应用图像分类(image classification),这是使用计算机视觉和机器学习算法从图像中抽取意义的任务。这个操作可以简单的为一张图像分配一个标签,如猫、狗还是大...

We believe various transfer learning methods will be proposed in the near future to extend the influence of herb image classification in the research community. Another related problem is how to jointly use the herb image data from different domains, namely, domain collaboration. For example, some...
