Definition
Video Super Resolution involves using neural networks to upscale video content from lower resolutions (e.g., 480p) to higher resolutions (e.g., 4K) while preserving detail and reducing artifacts. Unlike image super-resolution, VSR must also handle temporal consistency to avoid flickering between frames. It typically employs recurrent neural networks or transformers that leverage information from neighboring frames to reconstruct high-frequency details, resulting in sharper, clearer video output.
Summary
Video Super Resolution (VSR) is a computer vision technique that enhances the spatial and temporal resolution of low-quality video frames using deep learning.
