GGHL: A General Gaussian Heatmap Label Assignment for Arbitrary-Oriented Object Detection
👋 👋 👋
This is the implementation of GGHL [Arxiv] [IEEE TIP] [Google Drive][Baidu Disk (password: yn04)]
IEEE的正式版排版丑死了(不得不吐槽),有的图还显示有问题,还是下载arxiv版本的吧,我已经更新了arxiv,内容和正式版一样。
TensorRT C++部署版本教程和Nvidia Jetson嵌入式部署版本教程看这里!!! 感谢最最亲爱的师弟Crescent-Ao和haohaoolalahao
TS-Conv里,TS-Conv的代码放出来了在这里(还在更新完善中)
GGHL基础上改进的标签分配写到了新论文DKED在这里(用来Social和旅游的会议),这个等年底有空了扩写和更新代码

🌈 1.Environments
Linux (Ubuntu 18.04, GCC>=5.4) & Windows (Win10)
CUDA > 11.1, Cudnn > 8.0.4
First, install CUDA, Cudnn, and Pytorch. Second, install the dependent libraries in requirements.txt.
conda install pytorch torchvision torchaudio cudatoolkit=11.3 -c pytorch
pip install -r requirements.txt
🌟 2.Installation
-
git clone this repository
-
Polygen NMS
The poly_nms in this version is implemented using shapely and numpy libraries to ensure that it can work in different systems and environments without other dependencies. But doing so will slow down the detection speed in dense object scenes. If you want faster speed, you can compile and use the poly_iou library (C++ implementation version) in datasets_tools/DOTA_devkit. The compilation method is described in detail in DOTA_devkit .
cd datasets_tools/DOTA_devkit
sudo apt-get install swig
swig -c++ -python polyiou.i
python setup.py build_ext --inplace
🎃 3.Datasets
- DOTA dataset and its devkit
(1) Training Format
You need to write a script to convert them into the train.txt file required by this repository and put them in the ./dataR folder.
For the specific format of the train.txt file, see the example in the /dataR folder.
image_path xmin,ymin,xmax,ymax,class_id,x1,y1,x2,y2,x3,y3,x4,y4,area_ratio,angle[0,180) xmin,ymin,xmax,ymax,class_id,x1,y1,x2,y2,x3,y3,x4,y4,area_ratio,angle[0,180)...
The calculation method of angle is explained in Issues #1 and our paper.
(2) Validation & Testing Format
The same as the Pascal VOC Format
(3) DataSets Files Structure
cfg.DATA_PATH = "/opt/datasets/DOTA/"
├── ...
├── JPEGImages
| ├── 000001.png
| ├── 000002.png
| └── ...
├── Annotations (DOTA Dataset Format)
| ├── 000001.txt (class_idx x1 y1 x2 y2 x3 y3 x4 y4)
| ├── 000002.txt
| └── ...
├── ImageSets
├── test.txt (testing filename)
├── 000001
├── 000002
└── ...
There is a DOTA2Train.py file in the datasets_tools folder that can be used to generate training and test format labels. First, you need to use DOTA_devkit , the official tools of the DOTA dataset, for image and label splitting. Then, run DOTA2Train.py to convert them to the format required by GGHL. For the use of DOTA_devkit, please refer to the tutorial in the official repository.

👻 👻 最近大家提问和反馈比较多的是论文里对ORC做refined approximaation(RA) 的问题,这里额外解释一下。
ORC和Gliding Vertex有很多相似之处,对于Gliding Vertex,当凸四边形OBB的四个顶点不全部落在外接HBB上时是无法表示的,因此Gliding Vertex是先利用cv2.minRect函数将DOTA标注的凸四边形OBB转换为旋转矩形,然后在利用在HBB上的滑动顶点进行表示以保证OBB所有四个顶点都落在HBB上,具体见他们仓库的issue MingtaoFu/gliding_vertex#21 (comment). 在此基础上有了Oriented R-CNN的进一步简化用delta alpha和delta beta表示(因为内接OBB都已经近似成矩形了,两边是轴对称的,只需要预测在内接矩形相邻两条边的滑动距离即可)。但是这样的近似实际预测的还是旋转矩形而不是任意凸四边形,近似本身就会在GT上带来更多误差,误差更大的GT作为学习目标自然会影响预测准确性。因此,GGHL的RA只对那些该表示无法处理的凸四边形(即顶点不全落在HBB上的四边形)进行近似,而其他凸四边形都可以直接用ORC表示无需再近似成最小矩形,论文中也提到根据统计“only 4.79% of the OBBs need to be approximated”,这样可以保证ORC表示法在生成GT时引入的误差可以最小,论文表5的实验也证明了其有效性。更具体地,这些4.79%无法用ORC直接表示的凸四边形我们也不是全部用cv2.minRect做近似,而是精细地把他们分成16种情况进行讨论和分别处理,这样做目的是尽可能地减小因为近似带来的误差。大家也可以把上述近似和cv2.minRect近似的四边形画出来对比一下它们俩的误差。具体方案见论文图7和代码。
-
👹 👹 找了个动图,这样更好理解ORC和Gaussian的关系(外边是凸四边形的滑动,里面是高斯椭圆),很遗憾论文没能把完整的几何证明给出,后续版本会更新。
顺便再解释一下这个,这个动图是为了解释自适应调整高斯分布的,高斯根据ORC的顶点滑动(或者说凸四边形的变化)改变。根据OBB生成高斯通常是将OBB视为矩形,然后根据矩形的中心点坐标和长宽来得到高斯椭圆,但是如上RA问题的解释所述,GGHL的OBB不一定是矩形,而是任意凸四边形(有一部分对ORC无效的做了上述近似),那么要如何生成高斯?一种做法是仍然将凸四边形近为旋转举行计算高斯,另外一种就是我们给出的动图这样的做法。在我们最新的工作中会对这个进行更详细的讨论,快出来了(

12.31 I have updated the function of polyiou and polynms. Happy new year!!!
-
12.28 I have updated the requirements.txt file because the distributed training may prompt that some dependent libraries are missing.
-
更新了requirements.txt文件,因为DDP分布式训练时可能提示缺少一些依赖库。如果遇到这种情况,请根据提示pip安装补全相应的库即可。

😺 😺 12.23 因为论文还在审稿阶段的原因,消融实验还差一些代码没有完全更新完,稍安勿躁,持续更新中。
有问题真的真的可以在issues里面留言不一定非得邮件,我都会回的,这里可能比邮件还快的。邮件最近又有被放到垃圾箱的情况了,真的非常抱歉。有谁知道怎么关闭邮件拦截,恳请教我一下。另外,请不要做伸手党直接要代码或者让我直接帮忙写代码,这真的让人心情不美丽
-
🙉🙉 12.23 我不喜欢过度的评价别人的方法,我觉得每个工作都有它的闪光点和值得学习的地方,我学习论文和审稿也都是这样要求自己的,所以我个人拒绝回答觉得和xxx工作比起来怎么样这种问题,请见谅。GGHL这个工作欢迎任何批评和评价,我都会虚心接受作为激励。

12.17🧑🚀 今天没有更新。感慨一句,对于一个深度学习任务而言,有一个成熟的benchmark是一件幸事也是最大的不幸,当大家乐此不疲于此,这个领域就死掉了。 -

12.13😭 改论文改的头昏脑胀,补了一堆实验和解释,改论文比写论文难产多了~/(ㄒoㄒ)/~我可以选择剖腹产吗... -
12.11😁 修复了两个索引的bug。调整了学习率重新训练了,conf_thresh调到0.005,DOTA数据集精度能到79+了。顺便回复一句,总是有人问area normalization那个公式设计怎么来的,我睡觉梦到的。 -

11.22👺 Notice. Due to a bug in the cv2.minAreaRect() function of different versions of opencv, I updated datasets_obb.py, datasets_obb_pro.py, augmentations.py, and DOTA2Train.py. Opencv supports version 4.5.3 and above. Please note the update. Thank you. Thanks @Fly-dream12 for the feedback.
不同版本opencv的cv2.minAreaRect()函数不一致且存在一些角度转换的bug (我用的低版本角度是(0,-90],新版的是[0,90],所以可能有一些bug,我全部更新统一到新版了现在。还有就是cv2.minAreaRect()函数本身的一些bug,有很多博客介绍过了我就不重复了,由于我的原版为了解决这些bug做的判断函数和新版cv2.minAreaRect()的输出不太一样,这里也有一些问题,我也修改了),我更新了datasets_obb.py, datasets_obb_pro.py, augmentations.py, DOTA2Train.py文件,全部按长边表示法计算(角度范0,180)),请大家及时更新,opencv版本也请更新到4.5.3及以上。谢谢。

💣 11.6 更新了标签分配和dataload。更新了pytorch1.10版本的支持。预告一下,下周会更新分布式训练的内容。
(预训练权重的链接在NPMMR-Det和LO-Det的仓库说明里)
🙈 正文开始前的惯例的碎碎念(可以跳过直接看正文使用说明)
投稿排队实在太慢了,三个月了还在形式审查没分配AE,555~ 先在arxiv上挂出来了。
我会尽最大努力帮助大家跑通代码和复现出接近论文报道结果的实验,因为我自己也被坑多了,好多遥感领域的论文不开源代码或者根本复现不出来,或者就是模型复杂到眼花缭乱换个数据/参数就失灵,实在是太难了。论文里关于NPMMR-Det和LO-Det的实验代码会在那两个仓库里面更新,NPMMRDet的baseline目前已经更新完了,你们可以试试看能不能跑。LO-Det的正在更新中,可以看那边的说明(11.1也更新了)。
万一有AE或者审稿人大佬看到这个仓库,跪求千万别忘了审稿啊~ 求求,希望能顺利毕业
😸 😸 10.24 终于分配AE和审稿人了🐌 🐌 🐌 ,不容易啊。这投稿流程可太慢了,担心能不能赶上毕业,真的是瑟瑟发抖😭 😭 😭
🙉 🙉 关于论文超参数和实验的一些说明。
另外,请不要做伸手党,如果你们想训练自己的数据集,以下已经详细描述了GGHL的数据格式和使用说明,在tools文件夹中提供了转换脚本。我也在许多论文以外的数据集和大家提供的数据集上进行了实验,都可以正常工作,请花些时间阅读说明和issues #1中的一些解释,如果还有疑问可以在issues中留言给我,都会得到回复。我没有义务直接帮你们改代码和训练你们的数据。
