you should change the function data_config.get_data_config() , the self.root_dir should use your own address

针对LEVIR_CD数据集,我直接缩放到256*256之后,精度在49左右,是什么原因拿。。

resize 对图像影响较大,举个极端例子,本来变化区域是50个像素点构成的房子,经过你这种操作后,变化区域只有1个像素点,相当于增加了检测难度

你好,我有一个问题想请教一下。为什么我使用DSIFN数据集训练的时候。

出现了这个错误,想问一下怎么解决

哦哦,好的。十分感谢你的回答。对于LEVIT_CD数据集和WHU-CD数据集应该全都使用裁剪成256的是吗? 针对DSIFN-Dataset 数据集里面的标签和图像的大小不是很一样,那这个时候我应该直接把标签放大到512512进行训练吗?

DSIFN-Dataset数据集我没有用,不太了解您说的具体情况,我也在学习这个网络。1852916323qq

But your change label is also resized to 256*256.

你好,这个list文件是程序生成的吗?还是需要自己处理呢?

代码没有分割吗?为什么要resize

Mrwang989 avatar Mrwang989 commented on September 26, 2024

代码里没有分割呀 只是说了图像的大小 需要自己进行分割

需要自己对文件名进行提取

你好,原数据集是需要自己手动分割成256吗?然后用分割后的数据集进行训练?您最后跑出来精度有多高呀?

when I run sh scripts/run_CD.sh, there is a OSError: path to the root of LEVIR_CD dataset/list/trainval.txt not

Did you find any solution to this? I am facing the same problem.
