Why did you write ASPP in sequential manner with skip connections?

[aj96]

I thought the original idea of ASPP was to have parallel convolutions with varying dilation rates and then concatenate them all together. But you do ASPP in a sequential manner with skip connections. Do you have specific reasoning for this? Judging from the ablation experiments, it seems like the ASPP did not have much of an effect.

DASPP used in our work is from Yang et al, "DenseASPP for Semantic Segmentation in Street Scenes," CVPR 2018.
In our experiments, it does give much improvement in performance.

Is the usage of DASPP specifically good for Street Scenes and 720 pixel focal length ?
