Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Background:

Biometric recognition uses biological or behavioral traits like fingerprints or facial features for identification.
The brain, a complex organ, presents a potential novel biometric trait due to its inherent uniqueness.

Purpose of the Study:

To analyze the uniqueness of brain patterns for identity authentication.
To develop and evaluate a brain-based verification system.

Main Methods:

A two-stage system involving gray matter extraction and gray matter matching was proposed.
A modified brain segmentation algorithm was used for gray matter extraction.
An alignment-based matching algorithm was developed for brain image comparison.

Main Results:

Experimental results on two datasets demonstrated high accuracy in identity authentication.
The proposed brain recognition system meets stringent accuracy requirements.

Conclusions:

Brain images exhibit high uniqueness, offering potential for authentication.
Despite current limitations in acquisition time and cost, brain-based biometrics show promise for future security applications.
