Feature-Based Comparative Evolution of Amphibian Iris Patterns

Abstract

The use of animal biometrics has gained importance for reliable individual identification, with iris patterns offering a stable and distinctive characteristic for each organism. This study focuses on analyzing iris patterns in frogs by examining both geometric and color-based features. The objective is to identify key attributes that can support ecological research, biodiversity monitoring, and species conservation, while also enabling unique identification of individual frogs. The methodology involves capturing images of amphibian eyes, followed by iris localization and segmentation. Subsequently, feature extraction is performed using a combination of geometric descriptors and color characteristics to evaluate variations across different samples.
