Abstract
Adaptive spatial compounding with warping, a nonrigid image registration method developed for needle guidance during an epidural anesthesia is tested on ocular imaging. Ten ex vivo bovine eyes were imaged in total. FWHM values of the pixel intensity along the corneal surface were calculated. It was shown that the adaptive spatial compounding with warping produced the sharpest and the smoothest corneal reflection (FWHM=507.4 um, standard deviation=140.3um) over the conventional spatial compounding method.
