The healthcare sector of today has very precise requirement with regard to interior lighting. To fulfill these needs, international standards which specify the strict requirement for each health care facility have come up. Hospital lighting is in particular complex because of the sensitive nature of various patients as well as requirement of high performance from its employees. Hence this makes...

It is often necessary to estimate the response of a camera under given lighting conditions, or perhaps to estimate lighting requirements for a particular camera. To assist with these calculations a number of examples are given below for common problems. It should be recognized that very accurate calculations are difficult; it is often better to start with a simple estimate and then fine tune th...

Marker field is an image pattern that can be efficiently detected in a camera image, then exactly localized, even when heavily occluded, under strong motion blur, and under terrible lighting conditions. This work aims at synthesis of colored marker fields with the following goals in mind: the marker fields should be aesthetically appealing; they must be easily and reliably detectable; the marke...

Advances in computer graphics have led to the development of interactive entertainment applications with complex 3D graphical environments. Lighting is becoming increasingly important in such applications not only because of its role in illumination, but also because of its utility in directing the viewer’s gaze to important areas and evoking moods. However, lighting design is a complex process...

Camera based tasks are commonly perfcrmed during orbital operations, and orbital lighting conditions, such as high contrast shadowing and glare, are a factor in performance. Computer based training using virtual environments is a common tool used to make and keep crew members proficient. If computer based training included some of these harsh lighting conditions, would the crew increase their p...
