可否检查一下数据集，参在大量问题。部分图片未标注，且很多图片标注有明显错误

好的，我们检查一下，晚点回复你

谢谢。 （我这边用你们提供的voc2coco的脚本转换后，用mmdetection的fasterrcnn训练map 为一直不到1 怀疑是数据的问题，测试了其他数据集没有出现类似情况，用你们提供的voc格式训练了yolov4 也是出现了同样的问题）。

数据集更新了没？

@sunjiaen please can you share the dataset on my email as a zip file? as i tried opening it multiple times via the link and its password u had provided. but it didnt work. i would be grateful to ur response

你好，我观察到论文中你们使用自己的数据集进行实验，有一类检测不到，包括yolov4模型也有一类检测不到，在进行算法改进时，我发现map0.5到了0.8左右，就已经提高不了了（注意：我使用原始yolov5s进行实验，并且使用608*608尺寸进行训练），无论是加入小目标检测层，还是加入bifpn这种硬性网络，网络效果还是不够，我在想是否是数据集有问题呢

Dear Sir,

I hope you are doing well. I am a final year student of MS Data Science at Bahria University, Islamabad Campus. I am conducting research on the topic of "Ships detection and classification at night for maritime surveillance."

While searching for open-source datasets on platforms such as Kaggle and Ship Spotting website etc, I realized that there are very few real images of ships at night or low illumination. Most datasets available online rely heavily on synthesized images, which may not accurately reflect real-world scenarios. However, I was highly impressed by your work and the idea of creating a dataset of ships at night on your own.

Therefore, I am writing to kindly request your assistance in providing me with the dataset that you have prepared. If this is paid I am willing to buy your dataset. I believe that your dataset could be of great value to my research, and I would be extremely grateful for your support. Your help would contribute significantly to the success of my research, and I would be honored to acknowledge your contribution in my work.

Thank you for your time. I look forward to hearing back from you soon.

Best regards, Adnan

可否检查一下数据集，参在大量问题。部分图片未标注，且很多图片标注有明显错误 数据集确实存在一些错误，部分图片没有标注完全。请问您是怎么解决的，重新标注吗？
