Question

我想做一些关于衣服分割的事情，所以我需要在具有服装类的数据集上训练网络。有谁能回答我？我在http://mscoco.org/

中找不到关于课程的内容

Answer 1

您可以在实例注释json文件中找到coco的对象实例类别（可以在download页面中找到）。
下载并阅读该文件，您将看到带注释的类别：

In [1]: import json    
In [2]: with open('./instances_val2014.json','r') as R:
   ...:     js = json.loads(R.read())
   ...:
In [3]: js.keys()
Out[3]: [u'info', u'images', u'licenses', u'annotations', u'categories']
In [4]: js['categories']
Out[4]:

正如你所看到的，除'tie'类别外，那里的衣服不多......

另一方面，您可能会发现DeepFashion dataset有用。

我想知道MS COCO数据集中是否有衣服对象类？
