GenAI-Powered Spatio-Temporal Fusion for Video Super-Resolution

Based on PyTorch, Install Here

Exploring the forefront of generative AI to enhance video quality through advanced spatio-temporal fusion techniques by Upscaling and Frame-Interpolation, leveraging Auto-Encoders, LSTM Networks and Maximum Entropy Principle.

Introduction

This project is a novel approach to enhance video resolution both spatially and temporally using generative AI techniques. By leveraging Auto-Encoders and LSTM Networks, the project aims to interpolate high-temporal-resolution grayscale images and colorize them by learning from a corresponding set of RGB images, ultimately achieving high-fidelity video super-resolution.

Research Objective

The main goals of the project are:

• To learn temporal dependencies among spatially-sparse-temporally-dense greyscale image frames to predict and interpolate new frames, hence, increasing temporal resolution.
• To learn spatial dependencies through spatially-dense-temporally-sparse sequences that include both greyscale and corresponding RGB image frames to generate colorized versions of greyscale frames, thus, enhancing spatial resolution.

Here's a visual representation of the data transformation:

• During Training :
  • Input: [Grey-1] [Grey-2, RGB-2] [Grey-3] [Grey-4, RGB-4] ... [Grey-8, RGB-8] [Grey-9] [Grey-10, RGB-10]
  • Targeted Output: [RGB-1] [RGB-2] [RGB-3] ... [RGB-8] [RGB-9] [RGB-10]
• During Inference :
  • Input: [Grey-1] [Grey-2] [Grey-3] [Grey-4] ... [Grey-8] [Grey-9] [Grey-10]
  • Expected Output: [RGB-1] [RGB-1.5] [RGB-2] [RGB-2.5] ... [RGB-8.5] [RGB-9] [RGB-9.5] [RGB-10]
