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...

Classification In this example, we are going to perform a land cover classification using a Landsat image in Iowa and hand labeled training data. In the training data, there are four classes in total: Developed Area, Forest, Planted/Cultivated, and Water. ...
