MAGPIE
A real-time upscaling software that can upscale any application
A real-time upscaling software that can upscale any application or game window. Forked from Blinue/Magpie, with the intention of maintaining Visual Novel specific presets. Run Magpie and keep it open in the background / minimize to tray. Open the desired game / visual novel in windowed mode. Use Alt + F11 hotkeys to upscale your game window using magpie. Modify the ScaleModels.json if you want your very own custom stack of presets to use with Magpie. You'll need to start Magpie as admin if you want to upscale a game that's also running with admin privileges. Uses the CAS filter from FSR. Higher overall contrast and sharpness. I used this one instead of the standard CAS cause IMO it makes the details stand out a lot more. ACNet works very well for anime type art, looks very clean with think lines at the cost of some detail loss. -

Real-ESRGAN GUI
Cross-platform GUI for image upscaler Real-ESRGAN
The graphic interface of Real-ESRGAN, a practical and beautiful image magnification tool, refers to the design of waifu2x-caffe. This program is a graphical interface of Real-ESRGAN's command line program Real-ESRGAN-ncnn-vulkan , written in Python and tkinter, and supports Windows, Ubuntu and macOS platforms. According to actual measurements, arm64the single-architecture performance is better than universal2the dual- architecture Mac on the Apple chip, so Apple chip users are advised to pack arm64single-architecture applications by themselves. Real-ESRGAN can only enlarge the input image with a fixed 2-4x magnification (related to the selected model). This functionality is achieved by downsampling using a conventional scaling algorithm after multiple calls to Real-ESRGAN. Split each frame of the GIF and record the duration, zoom in one by one and then merge. Drag an image file or directory to any position in the window, and its path can be automatically set as the input. -

OptiScaler
OptiScaler bridges upscaling/frame gen across GPUs
OptiScaler is an open-source modding tool designed to enhance graphics performance and flexibility in modern PC games by allowing users to replace or modify built-in upscaling technologies. Instead of relying on the upscaling method originally integrated by a game developer, the software intercepts the game’s rendering pipeline and redirects it to alternative technologies chosen by the user. This makes it possible to swap technologies such as NVIDIA DLSS, AMD FSR, or Intel XeSS even if the game only supports one of them by default. The tool effectively acts as a compatibility layer between the game engine and multiple upscaling frameworks, enabling cross-GPU access to features that might otherwise be restricted to specific hardware ecosystems. In addition to replacing upscalers, OptiScaler can enable frame generation features in titles that do not officially support them, improving frame rates and perceived smoothness during gameplay. -

RENDER96-HD-TEXTURE-PACK
Texture pack for Super Mario 64
A collaboration texture pack for Super Mario 64 with the people over at the OldSchool HD, now known as Render 96, that is made of a compillation of the best results ESRGAN upscaling could make as the base for this project, as well of some of the original textures Nintendo used, and a heavier focus in original textures made by project contributors which will eventually be an overwhelming majority of what this project is made of. The end goal for this project is to use the original sources for every texture in the game when possible, and use that to hopefully achieve 100% accuracy by recreating the textures with the same process and resources Nintendo had at their disposal back in 1996, as well of incorporating elements from the promotional art into the game with ESRGAN upscales as placeholders for the original textures. The team and I will make to fill in the blanks where no texture sources could be found. -

Anime4kSharp
Anime4K implemented in C#
Anime4KSharp is a .Net Core library that implements bloc97's Anime4K Algorithm version 0.9 and 1.0 RC2. The Algorithm is executed on the CPU, but utilizing all available CPU Cores. This yields to a conversion time of "only" 4432 ms when upscaling from 1080p to 2160p. This time could possibly be reduced with further optimization. Images are processed in four phases that are executed on a pixel- per- pixel basis. Each phase takes a input image and renders it to a output image. This makes it easy to port the algorithm (back) to GLSL fragment shaders. As bloc97 described in his pseudo-preprint, the Anime4K algorithm is actually quite simple. -

FFmpegUpscalerHelper
A simple program with a UI for exporting video to png and encoding png
A simple program with a UI for exporting video to png and encoding png images to video using FFmpeg, for the purpose of upscaling. A simple program with a UI for exporting video to png and encoding png images to video using FFmpeg, for the purpose of upscaling. This program does not upscale your video, it's a tool to be used to save time for your upscaling process. Instead of opening CMD yourself and navigating to your ffmpeg location and then enter the command, this program does all that for you. Saves a lot of time when working with multiple videos. It does however require some knowledge of FFmpeg commands for you to be able to customize your encoding command for your needs. Encoding presets can be fully modified and comes with some decent default settings for x264 encodes. I plan to add more features in the future, this was just something I rushed together quickly in 2 days and has been extremely useful for me ever since. -

G2SConverter
Convert models from GoldSource engine to Source engine with AI
Convert models from GoldSource engine to the Source engine with AI. This utility converts GoldSource engine models to Source engine models. A feature of this utility is the ability to improve the quality of textures of models using Upscaling, deblurring, and normal map generating. All operations to improve the quality of textures are performed by neural networks. To improve the quality of the texture, it is first Upscaled using RealESRGAN. The user can select scaling factor: x2, x4 or x8. After the Upscaling procedure, the texture is deblured using the Scale-recurrent Network for Deep Image Deblurring. An example of a processed texture is shown in the following image (parameters used: scaling-factor = 4 and deblur iterations = 4) besides upscaling and debluring the utility also generates normal maps for each texture. This is implemented using the DeepBump by HugoTiny model. Examples of normal maps are shown in the following images. -

MNIST-WGAN
A C# WGAN
This project generates hand-written digits from the MNIST dataset using WGAN architecture. While debugged, a few lingering issues may remain, if you encounter any please submit them and they will be resolved. The sources and features of the project can be found in the wiki. Before use, one should verify that the network architecture is as-desired. This may be done with the GUI to the right of the number display. The "Default" button resets the network to hard-coded values which I have verified function. The "Reset" button sets the ACTIVE network to whatever architecture is displayed. In order to change which network is displayed, use the "Critic [1] or Generator [0]" checkbox. To begin training the network, press the "Train" button, after which you may use the "Clear" button to reset the average error and average percent correct value textboxes. In order to use the project on an alternative dataset, one must replace the MNIST files, then rewrite IO.FindNextNumber.
