Human Vision (Object Detection) and YOLO

How we humans detect and recognise object with our eyes:

1. Location: Turn our eyes to some direction (left, right, top, bottom, centre, or some random point)
2. Boundary: Detect the boundary
3. Classification: Any object? classify it.

YOLO (You Only Look Once) network does somehow similarly:

1. Location: Grid up an image (or video frame) to NxN, for example 3x3, that is also left, right, top, bottom, centre, etc.
2. Boundary: From a point in a grid cell, predict a rectangle, that is boundary
3. Classification: Any object? classify it.
