Hello, I think I don’t fully understand how object detection works… In the course Andrew says that the mid point of the object is detected, how is that done? And also, if an object is bigger than the grid cell size, how does the net know that those are parts of the same object? Thank you in advanc…

The mid-points are assigned in creating the training set. Someone looks at each image, clicks a mouse on what they think is the center of the object, and draws a box around it. The system learns that when it detects a specific pattern of pixels, it knows to output a box of the size it has learned f…
