4xFaceUpSharpLDAT
The sharper version of 4xFaceUpDAT that can handle lower quality input
Name: 4xFaceUpDAT
Author: Philip Hofmann
Release Date: 02.09.2023
License: CC BY 4.0
Network: DAT
Scale: 4
Purpose: 4x upscaling model for faces
Iterations: 140000
epoch: 54
batch_size: 4
HR_size: 128
Dataset: FaceUp (see dataset-releases channel)
Number of train images: 10'000

Description: 4x photo upscaler for faces, trained on the FaceUp dataset. These models are an improvement over the previously released 4xFFHQDAT and are its successors. These models are released together with the FaceUp dataset, plus the accompanying youtube video
This model comes in 4 different versions:
4xFaceUpDAT (for good quality input)
4xFaceUpLDAT (for lower quality input, can additionally denoise)
4xFaceUpSharpDAT (for good quality input, produces sharper output, trained without USM but sharpened input images, good quality input)
4xFaceUpSharpLDAT (for lower quality input, produces sharper output, trained without USM but sharpened input images, can additionally denoise)
