这个跟前两个一样,显着性检测貌似无法解决我的问题,准备换个方向解决我的问题了,虽然我的目的没达到,但是这个的效果确实还行的,有需要的可以好好调整一下。 使用链接: github.com/lartpang/MI…

 

原图 标签 预测结果 评价结果:

 

acc:  0.9055214352077908
acc_cls:  0.8682510382904347
iou:  [0.88870665 0.61525859]
miou:  0.7519826202767053
fwavacc:  0.8376228680494308
class_accuracy:  0.7143424443012731
class_recall:  0.7998325458213021
accuracy:  0.9007926079195722
f1_score:  0.7546741156614227

 

注意这个是我默认参数跑的,iou上来就是0.6以上了,感觉效果不错,不过这个跑的有点慢。

 

1.数据准备数据准备很简单,就是普通的存放方式 一级目录 二级目录 这里面的文件夹名字最好和我一样,代码里是通过这个名字拼凑路径的,另外,图像和标签的名字保持一样就行。 2.数据导入 这里要改的就是测试时的数据导入,训练的数据导入包含了测试和验证,我把训练时候的验证去掉了

4.预测训练完以后自动生成一个ouput文件夹,当你config.py文件都设置好以后这个会自动生成配置很多东西,记得测试要设置”resume_mode”: “inference”,结果存储的位置也在output里的pre文件夹中 下面是我传到百度网盘的参考,数据前面的博客提供了,这里面没放数据 链接: pan.baidu.com/s/1n1gfGEIm… 提取码:7477 复制这段内容后打开百度网盘手机App,操作更方便哦–来自百度网盘超级会员V5的分享
