Quesion about Blocks

[sshaoshuai]

Hi,
Thanks for sharing your codes.
I found that each room is splited into several blocks based on stride and block_size, and each block forms a batch which is segmented by the network independently, am I right?
If so, there will be a situation that one object (like a chair) is splited into different blocks, then the chair in a block will not be complete, so how could the network segment the incomplete chair well?

Thanks very much.

Splitting is a widely used strategy in literature because it is usually difficult to consume an entire scene in algorithms. And one object split into blocks could happen. Setting a smaller splitting stride could alleviate this problem in some sense. please refer to section 4.2 of our paper to see how it works.
