Nature: the corresponding sample and ground truth, how to select the appropriate sample and correspond to the real scene
Anchor: added to reduce the difficulty regression problem, provide a sample selection approach for classification. Difficulties: positioning fuzzy interference and background characteristics.
origin:

Proof: 1, can detect single FCN severe occlusion, target different scales
2, while producing a plurality of output single FCN and confidence score of prediction bbox
