关于鬼影的问题 #25
Comments
那个其实就是数据增强,并不高明的技巧 |
我仔细观察了一些样本,发现这些阴影毫无规则,大小不规则,深浅度各异,目前如果要从数据增强方面来看,需要解决如何生成一块阴影放置图像上。 实在不行就只能老老实实采集样本,调用打码平台去纠正图片,跑一批样本了,不过这样成本是昂贵的 |
生成并不困难,主要问题在于这种简单的无规律的数据增强往往效果不好,也就是无法让网络区分有规律的旋转变换和无规律的鬼影 |
是的,所以我感觉还是老老实实采集真实样本打标签吧 |
请问下有结果了吗?多少样本能有效果呢 |
没有,后续有其他事情就放置了 |
您好,我在52上看到了您的鬼影思路,但是还是没有很理解,可以有空详细的讲解下吗,盼复。
