Found it. |
@hupo376787 i'm glad you found a tool for your needs! Your mentioned tool, YoloLabel, is indeed a widely used tool for data labeling in YOLO format. It allows users to draw bounding boxes around objects of interest in images and generates corresponding annotation files. This makes it a helpful utility when creating labeled datasets for training YOLO models. Before you go ahead, I would like to suggest you check the quality of your labels regularly during the labeling process, especially if you are new to this. Accurate and consistent labels are very important for training a reliable model. Also, be sure to split your labeled images into training, validation, and testing datasets, so you can effectively train and evaluate your model. Happy labeling and best of luck with your AI journey! If you have any more questions down the line, feel free to reach out. |
Hi, Glenn. Thanks for your advice. I used YoloLabel for a while and found that it can only draw bounding boxes. This makes it an efficient tool. And I also heard that using a brush to paint is more accurate to train models. But it takes a little more time for a label engineer. So do you have any brush label tools recommended? Thanks. |
@hupo376787 hello, I'm glad to hear that you're exploring different means of labeling data and considering different tools. You're absolutely right: while bounding-box-based labels (like those created with YoloLabel) are indeed efficient, more precise labels - such as segmentation masks created by "painting" over the objects of interest with a brush tool - can potentially lead to better model performance, especially in applications which require a detailed understanding of object shapes. A tool worth exploring is labelbox, which has the brush tool you're looking for. It lets you paint over your object, creating more sophisticated segmentation masks as opposed to just boxes. For an open-source solution, you might want to look into labelme, which also supports polygon annotations. Keep in mind that this added complexity takes extra time and effort, during both the labelling process and the model training phase. It really depends on your specific use-case whether or not the improved performance from more advanced annotations is worth this additional investment. I hope this assists you in making an informed decision. If you need further guidance, feel free to ask. Happy labeling! |
@hupo376787 hello! That's right! The Ultralytics hub primarily supports the YOLO format for annotated training data. As a result, label tools such as YoloLabel that produce this desired output are suitable. However, this does not make other tools unusable. Tools like Labelme generate output in their own distinct format, as you've pointed out. However, the important point is that the raw information (object class, object coordinates etc.) remains the same, it's just organised differently. If you decide to use a tool like Labelme, you would have to convert the Labelme annotations to the YOLO format before you can feed it into the Ultralytics hub for training. This switch from one annotation format to another could be accomplished programmatically via a script. I hope this answers your question. If you have more, feel free to reach out! |
Understood, thanks for your reply. |

Question
Hi, I'm a newbie in AI. I found that this platform can train models using existing datasets, that's a great job.
But where does the dataset text come from? I have a lot of images, so what tool do I need to label?
Any advice is welcome.
