Conceptos Básicos

The EFHQ dataset provides a large-scale, high-quality collection of facial images with diverse head poses, enabling significant performance improvements across a wide range of face-related tasks, including synthesis, reenactment, and verification.

Resumen

The authors introduce the Extreme Pose Face High-Quality (EFHQ) dataset, a novel large-scale facial dataset designed to address the performance gaps between frontal and profile faces in various computer vision tasks. The key highlights of the EFHQ dataset are:

Extreme Pose: EFHQ contains up to 450k high-quality facial images with a wide range of head poses, including extreme profile and pitched views, to complement the predominant frontal views in existing datasets.
Large-Scale and High-Quality: The dataset is built by carefully curating and processing frames from two publicly available high-resolution face video datasets, VFHQ and CelebV-HQ, ensuring both large scale and high image quality.
Multi-Purpose: EFHQ is designed to be a versatile dataset that can benefit a wide range of face-related tasks, including 2D/3D image generation, text-to-image generation, face reenactment, and face verification.

The authors demonstrate the effectiveness of EFHQ through extensive experiments on these tasks. For image generation, models trained on EFHQ show significant improvements in handling extreme poses while maintaining performance on frontal views. For face reenactment, incorporating EFHQ data enhances the quality and consistency of the generated outputs, especially in profile views. Finally, the authors introduce a challenging pose-centric face verification benchmark using EFHQ, revealing the vulnerability of state-of-the-art face recognition models to extreme head rotations.

Overall, the EFHQ dataset represents a valuable resource for the computer vision community, enabling advancements in various facial analysis and generation tasks by addressing the critical gap in existing datasets regarding extreme head poses.
