Abstract
The integration of Neural Network Video Interpolation and Super-Resolution Techniques into a unified video processing framework aims to revolutionize video quality enhancement by enabling smoother motion transitions and higher resolution outputs. Neural network-based video interpolation predicts intermediate frames between existing ones, creating fluid motion sequences, while super-resolution methods upscale video frames to enhance detail and clarity. This project proposes a comprehensive framework combining these techniques to achieve high-quality video enhancement for applications such as content restoration, streaming services, and virtual reality.
Introduction
Video processing is a critical domain in digital media, with increasing demands for high-quality visuals in entertainment, surveillance, and streaming platforms. Challenges such as low frame rates and poor resolution degrade the viewing experience.
Neural network-based approaches for video interpolation and super-resolution have demonstrated significant improvements over traditional methods. However, integrating these techniques into a cohesive framework remains an open challenge. This project develops a unified video processing system that leverages the capabilities of neural networks for both interpolation and resolution enhancement, ensuring seamless motion and detailed visuals.
Existing System
- Traditional Video Interpolation:
- Utilizes linear or optical flow-based methods.
- Prone to artifacts such as motion blur and ghosting in complex scenes.
- Traditional Super-Resolution:
- Relies on bicubic or Lanczos upscaling.
- Limited by lack of contextual understanding and inability to reconstruct fine details.
- Neural Network Implementations:
- While effective, most implementations address interpolation and super-resolution as separate tasks, lacking a unified framework.
Proposed System
The proposed system combines neural network video interpolation and super-resolution into a single framework to enhance video quality comprehensively. Key features include:
- Integrated Workflow: Processes video input for both frame rate enhancement and resolution upscaling.
- Neural Network Models:
- Video interpolation using convolutional neural networks (CNNs) or generative adversarial networks (GANs).
- Super-resolution using models like SRGAN or ESRGAN.
- Artifact Reduction: Leverages advanced loss functions and temporal consistency checks to minimize visual artifacts.
- Real-Time Processing: Optimized for deployment in real-time applications such as live streaming and VR.
Methodology

- Super-Resolution:
- Apply super-resolution models such as ESRGAN (Enhanced Super-Resolution GAN) to upscale each frame to a higher resolution.
- Integration:
- Combine the outputs of interpolation and super-resolution processes to generate smooth and high-resolution videos.
