Hello, I have tried to convert the fast MRI Brain data set into PNG images in COCO format (I'm sure I flipped the images to align them with labels), and there are more than 3000 valid data.Then I called the open source target detection model for training, but the actual result was not ideal, the mAP could not exceed 0.1. I did some parameter experiments, but the result was not improved so far, so I began to doubt the quality and noise of the data set, and I hope to get confirmation from you
