Problems with resolution size settings

[6lly]

Hello, you mentioned in the experimental details that the resolution of the encoding phase mode, decoding layer and sensor plane is 320×320, 400×400 and 320×320 respectively, I would like to know why the resolution settings of the encoder and the decoder are different, will the resolution of the decoder set slightly larger will have a favorable effect on the generated result, I would appreciate it if you could answer my question.
