Experimental verifications of noise suppression in retinal recognition by using compression-based joint transform correlator

Noise-robust low-contrast retinal recognition using compression-based joint wavelet transform correlator

“…Recently, we have proposed and verified experimentally the use of compression-based joint transform correlator (CBJTC) for retinal recognition [12,13]. Our works have distinguishing feature compared to a conventional JTC in which joint photographic experts group (JPEG) algorithm is utilized to compress both retinal target and reference.…”

Experimental demonstrations of retinal recognition using compression-based joint transform correlator

“…In our proposed JTC, the JPEG-compressed target t C (x,y) and reference r C (x,y) are displayed side-by-side onto the EASLM. Under the presence of a white Gaussian noise n(x,y) at the input target, the joint input image can be written as 9 ) …”
