Vision-realistic rendering: simulation of the scanned foveal image from wavefront data of human subjects

We introduce the concept of vision-realistic rendering – the computer generation of synthetic images that incorporate the characteristics of a particular individual’s entire optical system. Specifically, this paper develops a method for simulating the scanned foveal image from wavefront data of actual human subjects, and demonstrates those methods on sample images. First, a subject’s optical system is measured by a ShackHartmann wavefront aberrometry device. This device outputs a measured wavefront which is sampled to calculate an object space point spread function (OSPSF). The OSPSF is then used to blur input images. This blurring is accomplished by creating a set of depth images, convolving them with the OSPSF, and finally compositing to form a vision-realistic rendered image. Applications of vision-realistic rendering in computer graphics as well as in optometry and ophthalmology are discussed.
