Real-ESRGAN-ncnn-vulkan VS chaiNNer

Don't even need topaz, there's plenty of free upscale models check the openmodeldb, and you have reve which is based on Real-ESRGAN-ncnn-vulkan.

Real-ESRGAN/GFPGAN https://github.com/xinntao/Real-ESRGAN (Real-ESRAN - Upscale images, facial restoration with GFPGAN setting) https://github.com/TencentARC/GFPGAN (GFPGAN - Facial restoration and Upscale) -------MATTE AND COMPOSITE--------

If you mean by free software, sure there are options. But you'll spend a lot of time to do that. You can try https://github.com/xinntao/Real-ESRGAN or similar tools

I’m actually on a Mac using the ncnn Vulkan binaries for Real ESRGAN. It’s not all that flexible but it’s pretty quick. There are other options but I have not looked into it.

I personally use real esrgan and I think it's great. it requires manual work tho but it's easy once you do it a few times

REAL-ESRGAN was used for upscaling (using waifu2x-extension GUI) and can be found here.

What are you trying to upscale? There's a whole lot of different upscalers out there, each best used for a specific type of image. If i do a cartoon character i want to blow up, i use RealESRGAN 4xAnime (6B) and then throw the upscaled image in Gigapixel AI and blow it up 6x. So in the end i get a super sharp 12k+ image out of it. You can download an upscale model and use it in Chainner on your local machine or throw it in the ESRGAN folder in your AUTOMATIC111 SD fork.

using ChaiNNer - https://github.com/JoeyBallentine/chaiNNer

I thought about doing something similar, but instead of creating my own project, I would have made a module for this one: https://github.com/joeyballentine/chaiNNer

For these, I used the software gigapixel AI. A free alternative is the process described here https://youtu.be/g_FlJ9yIG9U using this software. https://github.com/JoeyBallentine/chaiNNer

Alternatively, you could keep using your current model and correct the color shift. ChaiNNer has 2 nodes that can do this called "Average Color Fix" and "Color Transfer". Both nodes take your upscaled image and the original image (reference) and try to make the upscaled image look like the original image by shifting colors.

Here is the link https://github.com/joeyballentine/chainner and you download the models for ESRGAN from here https://upscale.wiki/wiki/Model_Database

Use ChaiNNer instead. Cupscale is outdated and hasn't been updated for a year.

I use this, https://github.com/joeyballentine/chaiNNer
