multi-scale inference #159

Open ed-Im opened 2 years ago

ed-Im commented 2 years ago

Is it right to improve the performance of the mIOU depending on whether multi_scale_inferance is used or not among config file options? The custom data set that I'm experimenting with showed worse performance. Can you explain the multi_scale_inferance function in detail? I'd like to know if it's the multi-scale information function I think.

[0.5, 1.0] multi scale
