Dataset prepare about yolov5

@Wenlong0913 hello! It's great to see your dedication to preparing your dataset for training with YOLOv5. 🚀

When it comes to dataset preparation, having all relevant objects labeled in your images is crucial for achieving high model performance. In your case, since humans appear in some of your images but are not labeled, this could potentially lead to the model learning to ignore humans or, worse, misclassifying them. This is especially important since you mentioned humans are one of your target classes.

While it might seem like a daunting task to go through your images to ensure all instances of your classes (human, cat, dog) are labeled, it's a necessary step for the kind of accuracy and reliability you're likely aiming for. Unlabeled instances of target classes can introduce noise into your training data, leading to poorer model performance.

Adding background images without your target classes can indeed help reduce false positives, but it doesn't substitute the need for accurately labeled data across your classes of interest. If manual labeling for every instance is too labor-intensive, you might consider semi-automated labeling tools or services to assist in the process, ensuring that every relevant object in your dataset is properly marked.

Remember, the quality of your training data directly impacts the effectiveness of your trained model. Taking the time to ensure it's as accurate and comprehensive as possible will pay off in your model's performance. 🌟
