What is Yolo you only look once?

You only look once (YOLO) is a state-of-the-art, real-time object detection system. On a Pascal Titan X it processes images at 30 FPS and has a mAP of 57.9% on COCO test-dev.

Hereof, what is you only look once?

You Only Look Once is an algorithm that utilizes a single convolutional network for object detection. Unlike other object detection algorithms that sweep the image bit by bit, the algorithm takes the whole image and.

One may also ask, what can Yolo detect? YOLO: Real-Time Object Detection. You only look once (YOLO) is a system for detecting objects on the Pascal VOC 2012 dataset. It can detect the 20 Pascal object classes: person.

Correspondingly, how many objects can Yolo detect?

Each grid cell make a fixed number of boundary box guesses for the object. However, the one-object rule limits how close detected objects can be. For that, YOLO does have some limitations on how close objects can be. For the picture below, there are 9 Santas in the lower left corner but YOLO can detect 5 only.

Why is Yolo fast?

YOLO is orders of magnitude faster(45 frames per second) than other object detection algorithms. The limitation of YOLO algorithm is that it struggles with small objects within the image, for example it might have difficulties in detecting a flock of birds. This is due to the spatial constraints of the algorithm.
