Can you describe the differences between class Pooler and class PoolerNeighbor?

Thanks for your nice work. I find that you use the class PoolerNeighbor instead of the class Pooler. It seems that the PoolerNeighbor only expand proposals. Can you describe the differences between class Pooler and class PoolerNeighbor?

@HuangLian126 Thanks for interested in our work. PoolerNeighbor expands the proposals before ROIAlign compared to Pooler. The function is at https://github.com/wuyuebupt/doubleheadsrcnn/blob/master/maskrcnn_benchmark/modeling/poolers.py#L165, called at https://github.com/wuyuebupt/doubleheadsrcnn/blob/master/maskrcnn_benchmark/modeling/poolers.py#L201.
