YOLOv3 implementation in TensorFlow 2.3.1
Role in this project:ML Engineer
ML EngineerContributions:215 commits, 9 PRs, 214 pushes in 2 years 5 months
Contributions summary:Rokas contributed to the YOLOv3 implementation in TensorFlow, focusing on the core functionality of the model. They modified the `utils.py` file, adding and updating functions related to image preprocessing, bounding box handling, and non-maximum suppression (NMS). The user was likely involved in integrating and refining the core object detection pipeline within the TensorFlow 2.x framework, specifically for YOLOv3.
