D-LORD

DYSL-AI Database for Low-Resolution Disguised Face Recognition.

Introduction

D-LORD is a large-scale dataset that aims at strengthening the research on low-resolution disguised face recognition. It is a dataset consisting of 2100 subjects captured with surveillance cameras where the subjects are donning various disguise artifacts such as face masks, hats, sunglasses, monkey caps, and wigs. D-LORD is the first large-scale real-world dataset that addresses the complex problem of low-resolution face recognition under disguise.

Intended Use & Licencing Information

Intended Use

The D-LORD database is designed for evaluating face recognition algorithms in surveillance, dealing with low-resolution and facial occlusions. It provides high-resolution (HR) mugshots and low-resolution (LR) surveillance camera images per subject.
D-LORD is extensive and unique for this research area. Notably, low-resolution face recognition under disguise is a new challenge highlighted by this database.
The database can be used for:
a) Evaluating face detection in low-resolution and disguised images.
b) Matching low-resolution probe images with high-resolution gallery images.
c) Studying the impact of disguise on recognition performance.
d) Reconstructing high-resolution images from low-resolution disguised images.
e) Detecting occluded regions in low-resolution images.
