This study introduces discriminative spectral regression (DSR), a new method for heterogeneous face recognition. DSR effectively maps images from different modalities into a shared subspace for improved accuracy.

Area of Science:

  • Computer Science
  • Artificial Intelligence
  • Biometrics

Background:

  • Face recognition systems often encounter challenges with images from diverse modalities (e.g., visual, near-infrared, sketch).
  • This heterogeneity complicates accurate face identification and classification.

Purpose of the Study:

  • To propose a novel method, discriminative spectral regression (DSR), for effective heterogeneous face recognition.
  • To develop a technique that maps images from different modalities into a common subspace for robust classification.

Main Methods:

  • The proposed discriminative spectral regression (DSR) transforms the subspace learning problem into a least squares problem.
  • Novel regularization terms are introduced to enforce closeness for same-class images and separation for different-class images within the learned subspace.

Published on: August 19, 2021

Main Results:

  • Experiments on two heterogeneous face databases demonstrate the effectiveness of the DSR method.
  • The proposed DSR method shows superior performance compared to existing heterogeneous face recognition techniques.

Conclusions:

  • Discriminative spectral regression (DSR) offers a robust solution for heterogeneous face recognition challenges.
  • The method's ability to learn a common discriminative subspace enhances classification accuracy across varied facial image modalities.
