SER-FIQ: Unsupervised Estimation of Face Image Quality Based on Stochastic Embedding Robustness

pterhoer/FaceImageQuality 20 Mar 2020

Face image quality is an important factor to enable high performance face recognition systems.

AI-KD: Towards Alignment Invariant Face Image Quality Assessment Using Knowledge Distillation

lsibabnikz/ai-kd 15 Apr 2024

To address this problem, we present in this paper a novel knowledge distillation approach, termed AI-KD that can extend on any existing FIQA technique, improving its robustness to alignment variations and, in turn, performance with different alignment procedures.

GraFIQs: Face Image Quality Assessment Using Gradient Magnitudes

jankolf/grafiqs 18 Apr 2024

We propose in this work a novel approach to assess the quality of face images based on inspecting the required changes in the pre-trained FR model weights to minimize differences between testing samples and the distribution of the FR training dataset.

SDD-FIQA: Unsupervised Face Image Quality Assessment with Similarity Distribution Distance

Tencent/TFace CVPR 2021

Thus, we propose a novel unsupervised FIQA method that incorporates Similarity Distribution Distance for Face Image Quality Assessment (SDD-FIQA).

Pixel-Level Face Image Quality Assessment for Explainable Face Recognition

pterhoer/ExplainableFaceImageQuality 21 Oct 2021

To achieve this, a model-specific quality value of the input image is estimated and used to build a sample-specific quality regression model.

QMagFace: Simple and Accurate Quality-Aware Face Recognition

pterhoer/QMagFace 26 Nov 2021

These variabilities can be measured in terms of face image quality which is defined over the utility of a sample for recognition.

Explainability of the Implications of Supervised and Unsupervised Face Image Quality Estimations Through Activation Map Variation Analyses in Face Recognition Models

fbiying87/explainable_fiqa_with_amva 9 Dec 2021

To avoid the low discrimination between the general spatial activation mapping of low and high-quality images in FR models, we build our explainability tools in a higher derivative space by analyzing the variation of the FR activation maps of image sets with different quality decisions.

CR-FIQA: Face Image Quality Assessment by Learning Sample Relative Classifiability

fdbtrs/cr-fiqa CVPR 2023

Based on that, our proposed CR-FIQA uses this paradigm to estimate the face image quality of a sample by predicting its relative classifiability.

FaceQgen: Semi-Supervised Deep Learning for Face Image Quality Assessment

uam-biometrics/faceqgen 3 Jan 2022

This comparison shows that, even though FaceQgen does not surpass the best existing face quality assessment methods in terms of face recognition accuracy prediction, it achieves good enough results to demonstrate the potential of semi-supervised learning approaches for quality estimation (in particular, data-driven learning based on a single high quality image per subject), having the capacity to improve its performance in the future with adequate refinement of the model and the significant advantage over competing methods of not needing quality labels for its development.

FaceQAN: Face Image Quality Assessment Through Adversarial Noise Exploration

lsibabnikz/faceqan 5 Dec 2022

In this paper, we propose a novel approach to face image quality assessment, called FaceQAN, that is based on adversarial examples and relies on the analysis of adversarial noise which can be calculated with any FR model learned by using some form of gradient descent.
