|[YOLO v2-coco](vision/object_detection_segmentation/yolov2-coco)|[Redmon et al.](https://arxiv.org/abs/1612.08242)|A CNN model for real-time object detection system that can detect over 9000 object categories. It uses a single network evaluation, enabling it to be more than 1000x faster than R-CNN and 100x faster than Faster R-CNN. This model is trained with COCO dataset and contains 80 classes.
|[YOLO v3](vision/object_detection_segmentation/yolov3)|[Redmon et al.](https://arxiv.org/pdf/1804.02767.pdf)|A deep CNN model for real-time object detection that detects 80 different classes. A little bigger than YOLOv2 but still very fast. As accurate as SSD but 3 times faster.|
|[Tiny YOLOv3](vision/object_detection_segmentation/tiny-yolov3)|[Redmon et al.](https://arxiv.org/pdf/1804.02767.pdf)| A smaller version of YOLOv3 model. |
-|[YOLOv4](vision/object_detection_segmentation/yolov4)|[Bochkovskiy et al.](https://arxiv.org/abs/2004.10934)|Optimizes the speed and accuracy of object detection. Two times faster than EfficientDet. It improves YOLOv3's AP and FPS by 10% and 12%, respectively, with mAP50 of 52.32 on the COCO 2017 dataset and FPS of 41.7 on Tesla 100.|

Trained on cityscapes dataset, which can be effectively implemented in self driving vehicle systems.|
|FCN|[Long et al.](https://people.eecs.berkeley.edu/~jonlong/long_shelhamer_fcn.pdf)|Deep CNN based segmentation model trained end-to-end, pixel-to-pixel that produces efficient inference and learning. Built off of AlexNet, VGG net, GoogLeNet classification methods.
