Ablation experiments about Deeplabv3plus

[duduzai2019]

Hi in the ablation experiments remove the aspp and c1_output module in the mmseg/models/decode_heads/sep_aspp_head.py, but with little change, the miou maintained at around 80％,
What is wrong? has been troubing me for a long time!

Hi, from the DeepLabV3+ paper figure it shows the c1_output (the yellow boxes below) contains low-level features which is very important for dense prediction tasks (such as semantic segmentation).

Thanks for your answer, i understand how it works, but i want to remove both modules in mmsegementation, Do i have a problem modifying it like this? (mmseg/models/decode_heads/sep_aspp_head.py class DepthwiseSeparableASPPModule)

Thanks again for your answer
