Abstract

The 8th edition of NTIRE: New Trends in Image Restoration and Enhancement workshop will be held on June 18th, 2023 in conjunction with CVPR 2023.

This work introduces a novel benchmark for efficient upscaling as part of the NTIRE 2023 Real-Time Image Super-Resolution (RTSR) Challenge, which aimed to upscale images from 720p and 1080p resolution to native 4K (x2 and x3 factors) in real-time on commercial GPUs. For this, we use a new test set containing diverse 4K images ranging from digital art to gaming and photography. We assessed the methods devised for 4K SR by measuring their runtime, parameters, and FLOPs, while ensuring a minimum PSNR fidelity over Bicubic interpolation. Out of the 170 participants, 25 teams contributed to this report, making it the most comprehensive benchmark to date and showcasing the latest advancements in real-time SR.

Towards Real-Time 4K Image Super-Resolution presents an exhaustive study of baseline methods for real-time SR. This paper serves as the official baseline for the challenge.

Efficient Deep Models for Real-Time 4K Image Super-Resolution. NTIRE 2023 Benchmark and Report gauges the state-of-the-art methods for real-time 4K upscaling using our new dataset and benchmark protocol. Multiple methods allow 60 FPS and even 120 FPS.
