Dataset Card for Latent Diffusion Super Sampling

Image datasets for building image/video upscaling networks.

This repository contains implementation of training and inference code for models trained on the following works:

Part 1: Trained Sub-Pixel Convolutional Network for Upscaling on 5000 individual 720p-4K and 1080p-4K image pairs

References: Real-time single image and video super-resolution using an efficient sub-pixel convolutional neural network, Shi et al

Shi, W., Caballero, J., Huszár, F., Totz, J., Aitken, A.P., Bishop, R., Rueckert, D. and Wang, Z., 2016.

Results:

720p images tested: 100
Average PSNR: 40.44 dB

1080p images tested: 100
Average PSNR: 43.05 dB

This outperforms the model in the proposed architecture (average is 28.09 dB)

Dataset Details

Consists of 300,000 ground truth 720p and 1080p frames with corresponding 4K output frames

Dataset Sources

YouTube

Uses

Diffusion networks, CNNs, Optical Flow Accelerators, etc.

Dataset Structure

1. All images are in .jpg format
2. Images are named in the following format: resolution_globalframenumber.jpg
3. Resolution refers to either of 3: 720p, 1080p or 4K
4. Globalframenumber is the frame number of the image under the respective resolution. eg: 4K_10090.jpg

Curation Rationale

1. To build a real-time upscaling network using latent diffusion supersampling.
2. Design algorithms for increasing temporal resolution (framerate up-conversion) of videos in real-time.
