Experimental demonstrations of noise-robustness of compression-based joint wavelet transform correlator in retinal recognition

Noise robustness of joint wavelet transform correlator with joint photographic experts group (JPEG) image compressions in low-contrast retinal recognition is experimentally demonstrated. The noise robustness is achieved by localizing particular spectra of joint power spectrum via a wavelet filter and an image compression of retinal targets. Besides being robust to noise, experimental results verify that image compression effects on the proposed retinal recognition are minimized.
