Toward a Realistic Simulation of Organ Dissection
Whilst laparoscopic surgical simulators are becoming increasingly realistic they can not, as yet, fully replicate the experience of live surgery. In particular tissue dissection in one task that is particularly challenging to replicate. Limitation of current attempts to simulate tissue dissection include: poor visual rendering; over simplification of the task and; unrealistic tissue properties....
متن کاملRealistic Simulation of Peripheral Vision Using An Aspherical Eye Model
A novel method is proposed to accurately simulate the peripheral vision under different visual perception. An accurate aspherical schematic eye model is firstly introduced to reasonably predict the anatomical and optical properties of the human eye. This eye model is composed of the Navarro schematic eye model with aspherical surfaces as a basic model, and a corresponding accommodation model, a...
متن کاملToward Realistic Simulation of Intervehicle Communication: Models, Techniques and Pitfalls
The quality of Intelligent Transportation Systems strongly depends on the underlying communication protocols and techniques. In this article, we discuss the current state of the art, trends, and open problems in the area of simulation techniques used to study Inter-Vehicle Communication (IVC). Complementary to testbed experiments that are often limited in scale and variety, simulation is one of...
متن کاملChapter 10 - Color Vision and Night Vision
Day vision and night vision are two separate modes of visual perception and the visual system shifts from one mode to the other based on ambient light levels. Each mode is primarily mediated by one of two photoreceptor classes in the retina, i.e., cones and rods. In day vision, visual perception is primarily cone-mediated and perceptions are chromatic. In other words, color vision is present in...
متن کاملTrue-Color Night Vision Cameras
This paper describes True-Color Night Vision cameras that are sensitive to the visible to near-infrared (V-NIR) portion of the spectrum allowing for the “true-color” of scenes and objects to be displayed and recorded under low-light-level conditions. As compared to traditional monochrome (gray or green) night vision imagery, color imagery has increased information content and has proven to enab...
