Post-Processing

Step

1. Simplify polygon by DP algorithm

2. Detect occlusion, calculating box fill with 1

3. Fill in reasonable sampling section

4. Output processed polygon

performance

It works, and a performance comparison on the MatterportLayout dataset:

Method	2D IoU(%)	3D IoU(%)	RMSE	$\mathbf{\delta_{1}}$
without post-proc	83.52	81.11	0.204	0.951
original post-proc	83.12	80.71	0.230	0.936
optimized post-proc	83.48	81.08	0.214	0.940
