Advancing Face Recognition for Low-Resolution with Multi-Linear Side Information-Based Discriminant Analysis

Face recognition is a key computer vision task that focuses on identifying or verifying individuals using their facial features. This task becomes more difficult with low-resolution images, where the reduced pixel count and detail make it harder to extract and match features accurately. In this study, we assess the effectiveness of Multilinear Side-Information-based Discriminant Analysis (MSIDA) on low-resolution images, using the CelebA database as a reference. The system showed strong performance, achieving 90.60% accuracy on high-resolution and 88.23% on low-resolution images, highlighting the robustness and effectiveness of MSIDA.
