Open Source Image Upscaling Apps

Free and Open Source AI Image Upscaler for Linux, MacOS and Windows built with Linux-First philosophy.

Image Super-Resolution [upscaling] for Anime-style [low detail] art or images using Deep Convolutional Neural Networks.

ComfyUI is an open-source, node-based workflow engine that empowers creators to design, customize, and run complex generative AI pipelines across images, video, audio, and more.

Video2X is a video/GIF/image upscaling software based on Waifu2X, Anime4K, SRMD and RealSR written in Python 3. It upscales videos, GIFs and images, restoring details from low-resolution inputs. Video2X also accepts GIF input to video output and video input to GIF output.

Real-ESRGAN aims at developing Practical Algorithms for General Image/Video Restoration.

A flowchart/node-based image processing GUI aimed at making chaining image processing tasks (especially upscaling done by neural networks) easy, intuitive, and customizable.

Magpie is a lightweight window scaling tool that comes equipped with various efficient scaling algorithms and filters. Its primary purpose is to enhance game graphics and enable non-fullscreen games to display in fullscreen mode.

An image, gif and video upscaling and denoiser app developed with electron, react, waifu2x and ffmpeg.

Video, Image and GIF upscale/enlarge(Super-Resolution) and Video frame interpolation. Achieved with Waifu2x, Real-ESRGAN, Real-CUGAN, SRMD, RealSR, Anime4K, RIFE, CAIN, DAIN, and ACNet.

Waifu2x Caffe rewrites only the conversion function of the image conversion software "waifu2x" using Caffe and is software developed for Windows. Although it can convert with CPU, using CUDA (or cuDNN) can convert faster than CPU.

RealScaler is a Windows app based on Real-ESRGAN AI to enhance, enlarge and reduce noise in photographs and videos.

An Android application for super-resolution & interpolation. Contains RealSR-NCNN, SRMD-NCNN, RealCUGAN-NCNN, Real-ESRGAN-NCNN, Waifu2x-NCNN, Anime4kcpp, nearest, bilinear, bicubic, AVIR...

2^x Image Super-Resolution ??.

jdPixelUpscaler upscales images by simply replacing one pixel with several of the same color. For example, if you set the scaling factor to 2, one pixel becomes 2x2 pixels of the same color. No attention is paid to the surrounding pixels or to transitions.

Recent state-of-the-art super-resolution methods have achieved impressive performance on ideal datasets regardless of blur and noise. However, these methods always fail in real-world image super-resolution, since most of them adopt simple bicubic downsampling from high-quality...

Simple free and open source tool used to upscale your low resolution images using advanced AI models

Image Upscaling GUI based on ESRGAN.

Upscaler is a GTK4+libadwaita application that allows you to upscale and enhance a given image. It is a front-end for Real-ESRGAN ncnn Vulkan.

Anime4KCPP provides an optimized algorithm version 0.9, and it also provides its own CNN algorithm, it provides a variety of way to use, including preprocessing and real-time playback, it aims to be a high performance tools to process both image and video.

MMEditing is an open source image and video editing toolbox based on PyTorch. It is a part of the OpenMMLab project.

This is GUI Shell for waifu2x-converter-cpp, Waifu2x Caffe, waifu2x-ncnn-vulkan, Real-CUGAN and Real-ESRGAN
