Overview

Neurobehavioral study reveals texture-color prioritization in pigeons, indicating that biological feature-weighting strategies can enhance fine-grained computational vision models.

Key Points

To examine how the avian visual system prioritizes co-occurring visual features and evaluate whether these biological rules can improve artificial visual recognition models.
Tested pigeons using behavioral delayed matching-to-sample tasks to quantify cue discrimination across texture, color, and shape.
Performed in vivo electrophysiological recordings in the entopallium alongside spectral-coherence-based functional connectivity analysis.
Constructed the Avian-inspired Feature Gating Model (AFGM) incorporating independent channel gating and sparse regularization, evaluating performance against an HVE baseline.
Behavioral and entopallial electrophysiological measures showed a persistent feature-prioritization hierarchy dominated by color and texture, while shape was secondary.
Entopallial functional connectivity grew sparser during information-rich tasks, demonstrating selective extraction of non-redundant features over uniform processing.
The AFGM framework demonstrated a modest performance advantage over the HVE baseline on fine-grained visual recognition benchmarks.
