I have one question for how to define the center point of the object.

If the mass-center of one object is (x, y), the center sample should be:

(x-1, y-1), (x-1, y), (x-1, y+1)
(x, y-1), (x, y), (x, y+1)
(x+1,y-1), (x+1,y), (x+1, y+1)
Am I right?

What if the mass-center of two objects is the same, just like the following picture?

How to define the center sample for the two object separately?

The PolarMask has 3 outputs:

classification: H*W*k
Polar Centerness: H*W*1
Mask Regression: H*W*n

In CornerNet or Centernet, the heatmap is used to represented a point. Is 1. classification: H*W*k the heatmap?
