New framework enhances iris recognition with occlusion identification and reconstruction

Researchers have developed a new framework for iris recognition that aims to improve accuracy even when parts of the iris are obscured. The system first identifies the type of occlusion, such as eyelids or eyelashes, using a 2D CNN. It then employs a diffusion model to reconstruct the occluded areas based on the identified occlusion type. Finally, a modified VGG19 network is used to extract features from the restored iris image for recognition, showing improved performance on the CASIA-Iris-Thousand dataset. AI

IMPACT This research could lead to more reliable biometric identification systems by overcoming common image degradation issues.
