Upscale images using onnx models
Recently, i have seen many app that started to use onnx models ( from openmodeldb.info ) to upscale images.
An i think It would be cool to add the ability to use onnx models, and be able to add custom models to upscale photos, as the other apps doesn't support adding custom models.
Just curious, what apps? Could you give me a few names because I'm trying to find apps for upscaling images locally.
But does it run locally? I want something that's free.
https://github.com/tumuyan/RealSR-NCNN-Android This one actually uses NCNN models. But for Super image pro, yes it can run ONNX models locally, but you still need subscription. I have recently seen other multiple apps that can run ONNX locally but still can't load custom models.
I'm already using that and it seems like it works the best for cartoon characters or images with a few colors because the models that work for me seem to make it sharper while getting rid of some details. And no, this doesn't only happen with the anime models. I even tried to add my own using the files found on the Huggingface but that failed.
It is actually really easy to add custom models. https://openmodeldb.info/ This website provides a lot of models, you will be able to find NCNN, but most of the models are ONNX and Pytorch. So you will have to use Chainner (on pc) to convert them to NCNN, but be aware that ESRGAN, ESRGAN+ ,and Real-CUGAN are convertible.
After that you will need to create a folder in the custom directory you have chosen to load your custom models and rename this folder : "models-ESRGAN-NameOfTheModel"
And then you gonna paste you bin and param files there.
And also don't forget to rename your bin and param file to x4.bin , x4.param so it can detect the upscale value.
And you are ready to go.
I know about openmodeldb and I have used the models from there on my computer but I was using the models found on the huggingface by the creator at https://huggingface.co/tumuyan2/realsr-models and I was having issues with running those models even after following the instructions. But thanks for the extra information!
