Mathematics in Digital Photography
The advances in both digital photography and computing have allowed more detailed and complex images to be shown on more realistic media than was ever previously possible. Through the use of more specialized equipment and digital imaging techniques the resulting photos of even the most novice user today can rival those of professionals from years before. This level of photographic precision could never have been achieved were it not for the tremendous advantages made in computing that allow both the hardware and software involved in digital photography to function at extremely high levels. Both hardware and software made today are capable of performing the necessary calculations in a fraction of a second, making focusing and editing pictures easier than ever before. The incorporation of mathematics directly into the digital photography process has been the primary impetus for the explosion of high-quality digital images available almost anywhere we look.
Mathematical Equations Used in Digital Photography
Digital cameras must receive light in much the same way the human does and, as a result of this, must find a way to model the typical responses of the cones in the eye. The mathematical model of this was first derived from John Dalton's description of his colorblindness. This response can be best represented by the following equation:
ci = max ?min...
Popular Culture in the Classroom From the wide range of materials teachers can use in the classroom, popular culture is one of the best sources. They appear to public attention as the indication of the rapid growth of the society. Many of the pop culture icons are mostly well-known, regionally and internationally. Students enjoy working with pop culture that they are familiar with. Some of them think that such materials
The student has provided research on various vibration analytic techniques such as the use of Laser Vibrometry for Damage Detection using Lamb Waves in discovery processes to detect microcracks. Outcome 3. The Information Literacy competency was satisfied through the research efforts made by the student through data gathering regarding aircraft structures and vibrations qualification techniques retrieved from the MIL-STD-810F and NASA Langley Research Laboratory. Techniques include Fatigue Damage Spectrum (FDS)
History Of Communication Timeline TIMELINE: HISTORY OF COMMUNICATION (with special reference to the development of the motorcycle) 35,000 BCE. First paleolithing "petroglyphs" and written symbols. This is important in the history of communication because it marks the first time humans left a recorded form of communication. Also, these written symbols became the ultimate source of later alphabets. Wikipedia, "Petroglyph." 12,600 BCE. Cave paintings at Lascaux show early representational art. This is important in the history of communication
Pedagogic Model for Teaching of Technology to Special Education Students Almost thirty years ago, the American federal government passed an act mandating the availability of a free and appropriate public education for all handicapped children. In 1990, this act was updated and reformed as the Individuals with Disabilities Education Act, which itself was reformed in 1997. At each step, the goal was to make education more equitable and more accessible to
Interactive art usually contains computers, sensors, and other devices that allow the art and the user to interact with each other. Video and computer games have brought a different set of artists to the field. The tools have changed as well with the advent of voice analyzers, robotics, actuators, LED's, and etc. Is the line between real reality and virtual reality getting blurred? Virtual describes the animated form and how closely
