What's the diffrent between U-net and WU-net?

[kangyang94]

Through your code , U-net and WU-net have the same architecture, just the dimension of input is different. So what's the diffrent between U-net and WU-net?

Although UNet++ achieves better performance than U-Net, the number of UNet++ also increases, specifically U-Net (7.76M) vs UNet++ (9.04M). It's possible that the performance boost is coming from the increased number of learn-able parameters. Thereby, given the number of UNet++, we compared a "wide" U-Net (9.13M) whose parameter is comparable with UNet++ (9.04M) and a little bit more to avoid the influence of purely increasing the parameter of U-Net like structure.

Is the performance of wide U-Net better than the original U-net?
