Have you ever tried to edit the results of PSP encoder directly to realize aging? #43

In your article, you redesigned an encoder similar to PSP encoder structure and added the coding results to the PSP results. Have you ever tried to edit the results of PSP encoder directly to realize age editing? thank

Yes. We tried editing with pSp directly and the results were worse. pSp encodes images into far regions of W+ and therefore the editing capabilities are limited compared to other approaches, including SAM. With SAM, since we split the encoding and editing process into two steps (i.e., the initial embedding and the residual representing the change in age), we are able to better preserve identity and capture the desired age.

This is consistent with my experimental results. Thank you for your reply
