There are some good detections, but there are many test pictures that cause recall and precision problems as follows. How can I solve this?
Oh, class 1 is pointing to number 2 in that table. I think the number of the results is a little behind, but I think I need to modify the code a little bit. I don't know where the part that needs to be modified((0.5:0.95:0.05)->[0.1,0.3,0.5]) right now, but I'll try to modify it.
First, I didn't have any test data, so I divided the training images and used them as test images. Comparing the results from the real model with the annotation of the image, Annotation failed to contain the results from the model. In other words, the actual image did not contain any defective parts in the annotation. So, when I tested it, the mAP had to be low. Of course, there were many patterns, so I think the results were wrong. Thank you in many ways. Is there any paper or data that you have referred to in the model part?

Since this competition only allows us to use COCO and imageNet as additional data, I only used the model pre-trained on COCO (from the official model zoo of mmdetection).
I think there may be similar data in the field of change detection in remote sensing image analysis (the picture before the change is used as the template image, and the picture after the change is the image to be detected).
In addition, there is a recently concluded tile defect detection competition on the Aliyun Tianchi platform, which also requires reasonable use of template images. The address is: https://tianchi.aliyun.com/competition/entrance/531846/introduction.
Hope these are helpful to you.
Thank you
Thanks to you, I have succeeded in training and performing the model.
I received through baidu, 17,000 annotations from the training data, and divided them into 9:1 and conducted training and testing.
Nothing has changed from the model, but the test results are not sure if it's normal or not.
Could you give me some advice?
My optimizer setting is only one GPU, so I set it as below.
