Generic Visual Perception Processor Essay Example for Free

Generic Visual Perception Processor Essay The generic visual perception processor (GVPP) has been developed after 10 long years of scientific effort . Generic Visual Perception Processor (GVPP) can automatically detect objects and track their movement in real-time  . The GVPP, which crunches 20 billion instructions per second (BIPS), models the human perceptual process at the hardware level by mimicking the separate temporal and spatial functions of the eye-to-brain system. The processor sees its environsment as a stream of histograms regarding the location and velocity of objects. GVPP has been demonstrated as capable of learning-in-place to solve a variety of pattern recognition problems. It boasts automatic normalization for varying object size, orientation and lighting conditions, and can function in daylight or darkness. This electronic eye on a chip can now handle most tasks that a normal human eye can. That includes driving safely, selecting ripe fruits, reading and recognizing things. Sadly, though modeled on the visual perception capabilities of the human brain, the chip is not really a medical marvel, poised to cure the blind Introduction of  GVPP The GVPP tracks an object, defined as a certain set of hue, luminance and saturation values in a specific shape, from frame to frame in a video stream by anticipating where its leading and trailing edges make differences with the background. That means it can track an object through varying light sources or changes in size, as when an object gets closer to the viewer or moves farther away. The GVPPS major performance strength over current-day vision systems is its adaptation to varying light conditions. Todays vision systems dictate uniform shadow less illumination ,and even next generation prototype systems, designed to work under â€Å"normal† lighting conditions, can be used only dawn to dusk. The GVPP on the other hand, adapt to real time changes in lighting without recalibration, day or light. For many decades the field of computing has been trapped by the limitations of the traditional processors. Many futuristic technologies have been bound by limitations of these processors . These limitations stemmed from the basic architecture of these processors. Traditional processors work by slicing each and every complex program into simple tasks that a processor could execute. This requires an existence of an algorithm for solution of the particular problem. But there are many situations where there is an inexistence of an algorithm or inability of a human to understand the algorithm. Even in these extreme cases GVPP performs well. It can solve a problem with its neural learning function. Neural networks are extremely fault tolerant. By their design even if a group of neurons get, the neural network only suffers a smooth degradation of the performance. It wont abruptly fail to work. This is a crucial difference, from traditional processors as they fail to work even if a few components are damaged. GVPP recognizes stores , matches and process patterns. Even if pattern is not recognizable to a human programmer in input the neural network, it will dig it out from the input. Thus GVPP becomes an efficient tool for applications like the pattern matching and recognition HOW IT WORKS: Basically the chip is made of neural network modeled resembling the structure of human brain. The basic element here is a neuron. There are large number of input lines and an output line to a neuron. Each neuron is capable of implementing a simple function. It takes the weighted sum of its inputs and produces an output that is fed into the next layer. The weights assigned to each input are a variable quantity. A large number of such neurons interconnected form a neural network. Every input that is given to the neural network gets transmitted over entire network via direct connections called synaptic connections and feed back paths. Thus the signal ripples in the neural network, every time changing the weighted values associated with each input of every neuron. These changes in the ripples will naturally direct the weights to modify into those values that will become stable . That is, those values does not change. At this point the information about the signal is stored as the weighted values of inputs in the neural network. A neural network geometrizes computation. When we draw the state diagram of a neural network, the network activity burrows a trajectory in this state space. The trajectory begins with a computation problem. The problem specifies initial conditions which define the beginning of trajectory in the state space.

Dr. Jekell And Mr. Hyde :: essays research papers

The Dominion of Evil The term â€Å"Jekyll and Hyde†, now a part of our common language, can be found in most dictionaries. Random dictionary definitions of â€Å"Jekyll and Hyde† include: 1) â€Å"One who has quasi-schizophrenic, alternating phases of pleasantness an unpleasantness.† 2) â€Å"A person having a split personality, one side of which is good and the other evil.† 3) â€Å"This phrase refers to a person who alternates between charming demeanor and extremely unpleasant behavior.† This concept revolves around the experience of Dr. Jekyll, enabled by drinking a potion, into living as his own living side, whom he names Hyde. Stevenson intended Jekyll’s character to be pronounced Je (French word for â€Å"I†) Kill (Je-Kill = I kill), as an indication that the doctor wanted to isolate the evil portion of himself, appropriately named â€Å"Hyde,† meaning low and vulgar hide or flesh which must hide from civilization. When R obert Louis Stevenson wrote the story Dr. Jekyll and Mr. Hyde, he portrayed man’s evil nature as a portion of his total makeup, and showed that the evil portion will often express itself more forcefully and powerfully than do the other aspects. Throughout life, a person can develop a sense of the conflict that actually involves one’s good and evil natures. Often a person’s current actions reflect their childhood experiences. Jekyll, described by Stevenson, born wealthy, grew up handsome, honorable, and distinguished. Yet, throughout much of his life, he commits secret acts which he thoroughly regrets. Early in Jekyll’s development, Stevenson had him recognize a â€Å"profound duplicity of life...so profound a double dealer† and â€Å"that man is not truly one, but truly two.† Intellectually, he evaluates the differences between his private life and his public life and, ultimately, he becomes obsessed with the idea that at least two different entities, maybe even more, occupy a person. Jekyll’s reflections and his scientific knowledge lead him to contemplate the possibility of scientifically isolating these two components. With this in mind, he begins to experiment with various chemical combinations. When Jekyll discovers the correct formula and drinks it, he is approaching a hardy fifty years of age; after his transformation into Edward Hyde, he feels younger, lighter, and more sensual, thereby indicating the appeal of the evil side. At that point, he acknowledges â€Å"the thorough and primitive duality of man.† He sees the necessity to try to separate the two selves, to hide that shameful part of himself from the world, and therefore stay in control of his evil nature.

Patato Chips

Baseball, hot dogs, potato chips, and pop. What can be more American than that? The potato chip is the king of salty, crunchy snacks. Potato chips originated in New England in 1853 at Moon Lake Lodge in Saratoga Springs, New York. The inventor, a chef named George Crum, was part Native American and part African American and a guide in the Adirondack area. The potato chip was invented when a dinner guest returned his fried potatoes to Chef George Crum because they were not crunchy enough. After returning the unacceptable fried potatoes twice, the irritated Chef Crum decided to annoy the customer by making the fried potatoes too thin to eat with a fork. The customer was surprisingly satisfied and the potato chip was invented. The invention of potato chips has had a positive impact on our country’s economy, the mechanized technology of potato chip production, and the popularity of chips as a main ingredient of social gatherings. Potatoes are second in consumption only to rice. As thin, salted crisp chips, they are America’s favorite snack. From the beginning, potato chips made a difference in the economic situation at Moon Lake Lodge in showing an increase of profits as the potato chips, the house specialty, began to appear In 1926 Laura Scudder developed the wax paper bag to preserve the chips, which permitted wider distribution. Sheets of waxed paper were ironed into bags. Chips were then hand packed and the bags were sealed on top with warm irons. This was the invention of the potato chip bag as we know it today and its manufacture has continued. Both the developments of the mechanical peeler and the wax paper led to the popularity of the chips beyond the northern part of the U. S. , where chips were mainly a restaurant dinner dish for decades. The development of pre-print waxed glassine bags in 1933 further expanded the sale of potato chips. With the increase of different chip manufactures around the country by 1929, the glassine bag provided improved quality of freshness for shipping time and allowed for advertising with company brand identification printed on the bag. In 1929, production of potato chips dramatically increased due to the invention of the continuous fryer. In the first part of the century, potato chip manufacturing was done in small batches in small kettles. The continuous fryer allowed for a greater scale of production and eliminated most of the kettle cooker companies. Potato chip manufacturing has provided employment in several areas such as factory production, production and printing of boxes and bags, advertising, and shipping. It has provided profits for stores and vendors who sell snacks at sport games, fairs, and recreational facilities.
