Introducing Vision-Realistic Rendering

We introduce the concept of vision-realistic rendering‐the generation of images that incorporate characteristics of a particular individual’s optical system. We then describe a pipeline for creating vision-realistic images. First, a subject’s optical system is measured by a Shack-Hartmann 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 image. We discuss applications of visionrealistic rendering in computer graphics as well as in optometry and ophthalmology and note that our method is a post-process and can handle simple camera models as a special case.
