This paper investigates a new method for generating high-quality synthetic training data for object detection (OD) algorithms. Utilizing photogrammetry, we transform real-world objects into 3D digital replicas in Unreal Engine 5 (UE5). We then simulate diverse scenarios, capturing images of these objects at varying angles, backgrounds, and textures. To evaluate the data quality, we experiment with...Show More
PULSE: Self-Supervised Photo Upsampling via Latent Space Exploration of Generative Models

The primary aim of single-image super-resolution is to construct a high-resolution (HR) image from a corresponding low-resolution (LR) input. In previous approaches, which have generally been supervised, the training objective typically measures a pixel-wise average distance between the super-resolved (SR) and HR images. Optimizing such metrics often leads to blurring, especially in high variance ...Show More
New Techniques for Preserving Global Structure and Denoising with Low Information Loss in Single-Image Super-Resolution

Cited by: Papers (17)
This work identifies and addresses two important technical challenges in single-image super-resolution: (1) how to upsample an image without magnifying noise and (2) how to preserve large scale structure when upsampling. We summarize the techniques we developed for our second place entry in Track 1 (Bicubic Downsampling), seventh place entry in Track 2 (Realistic Adverse Conditions), and seventh p...Show More

This paper reviews the 2nd NTIRE challenge on single image super-resolution (restoration of rich details in a low resolution image) with focus on proposed solutions and results. The challenge had 4 tracks. Track 1 employed the standard bicubic downscaling setup, while Tracks 2, 3 and 4 had realistic unknown downgrading operators simulating camera image acquisition pipeline. The operators were lear...Show More
