Most modern commodity imaging systems we use directly for photography—or indirectly rely
on for downstream applications—employ optical systems of multiple lenses that must …

Most camera lens systems are designed in isolation, separately from downstream computer
vision methods. Recently, joint optimization approaches that design lenses alongside other …

Blur occurs naturally when the eye is focused at one distance and an object is presented at
another distance. Computer-graphics engineers and vision scientists often wish to create …

Computer-graphics engineers and vision scientists want to generate images that reproduce
realistic depth-dependent blur. Current rendering algorithms take into account scene …

Vision-simulated imagery―the process of generating images that mimic the human visual
system―is a valuable tool with a wide spectrum of possible applications, including visual …

In vision-based object classification systems imaging sensors perceive the environment and
then objects are detected and classified for decision-making purposes; eg, to maneuver an …

Lens flare is caused by light passing through a photographic lens system in an unintended
way. Often considered a degrading artifact, it has become a crucial component for realistic …

Cameras with a finite aperture diameter exhibit defocus for scene elements that are not at
the focus distance, and have only a limited depth of field within which objects appear …

This self-contained tutorial surveys the state of the art in quasi-Monte Carlo rendering
algorithms as used for image synthesis in the product design and movie industry. Based on …

We present a practical real‐time approach for rendering lens‐flare effects. While previous
work employed costly ray tracing or complex polynomial expressions, we present a coarser …
