Open-source alternatives to CCSR

This work presents a novel Diffusion-Wavelet (DiWa) approach for Single-Image Super-Resolution (SISR). It leverages the strengths of Denoising Diffusion Probabilistic Models (DDPMs) and Discrete Wavelet Transformation (DWT). By enabling DDPMs to operate in the DWT domain, our DDPM models…

One-Step Effective Diffusion Network for Real-World Image Super-Resolution

CVPR2024 SeeSR: Towards Semantics-Aware Real-World Image Super-Resolution

Srez is a deep learning image super-resolution framework designed to upscale low-resolution images into sharp, high-resolution visual features. It functions as a neural network training tool that employs generative adversarial networks to synthesize realistic image details. The project includes a model evolution visualizer that generates animations and image batches to track visual improvements during the training process. It utilizes a combination of adversarial and L1 loss functions to optimize model weights and supports periodic state checkpointing for recovery and deployment. The system

This PyTorch-based image super-resolution tool provides a deep learning pipeline for upscaling low-resolution images. It utilizes generative adversarial networks to increase pixel density and reconstruct high-resolution image details. The system includes a GAN-based image upscaler and a training pipeline that optimizes neural network weights using paired datasets and custom loss functions. To manage hardware resources, a patch-based image processor splits high-resolution files into smaller segments to prevent memory allocation errors and system crashes. Additional capabilities include the ap

Library for Minimal Modern Image Super-Resolution in PyTorch

This project is a deep learning framework for AI image super-resolution and facial synthesis. It provides a diffusion model image upscaler and a generative facial image synthesizer capable of transforming low-resolution images into high-resolution outputs using pretrained model weights. The system utilizes iterative diffusion refinement and low-resolution guided sampling to restore fine details and sharpness. It supports both unconditional image generation, where images are created from scratch, and guided resolution enhancement for high-fidelity facial reconstruction. The repository include
