FEATURING MAPPING: FACIAL RECOGNITION Facial recognition is a form of computer vision technology (see opposite) that matches photographs or videos of human faces to those stored in a database. An image of a face is captured, and its distinctive features, such as the distance between the eyes, are mapped to create a unique "faceprint" that is then compared with known faceprints. Facial recognition is mainly used for security, such as an authentication process on phones and law

Alongside the similarities by the criteria hue, lightness and saturation, there are also fundamental differences between the cube model and the LCH color space. The Cube Describes the Color Model The cube always requires as a reference point primary colors, from which all other colors can be derived when mixed. Thus, the cube's practical application is describing the ratios of a set group of colors. A color value scale is one example. However, the cube is unsuitable when mixt

So, to summarize, in contradiction of the traditional view that the development of mathematics is purely cumulative, I have argued that revolutions do occur in mathematics, but are confined entirely to the metamathematical component of the community's shared background. It is this that gives mathematics its appearance of having developed cumulatively: its evolution is conservative on the object-lecel but revolutionary on the meta-level. Several example of revolutions in math

The ways of calculating energy requirements, that is of setting up energy balances around processing operations, and their basis in the first law of thermodynamics were introduced in the first chapter of this book. Anyone faced with designing or operating a food processing plant will have come answer. Two such problems are: how can we make best use of the various hot streams throughout a plant? what is the absolute minimum amount of energy or work that is needed for a particu

Dots and Lines The dot can be described as the most basic mark. Lines can either stand alone or be connected. A line can follow the general outlines of a subject. Lines can also have different qualities; they can be thick or thin, light or dark, free-flowing or rigid. Richmond Teye Ackam positions lines and dots to create a cohesive image in his painting Red and Black, below. Shape We can create a shape by joining several lines together. The shape can also be referred to as t

Many scientists and philosophers have remarked on the powerful role played by mathematics as the language of the exact sciences. The use of mathematics reveals unsuspected connections in nature and generates new discoveries and new concepts. The best scientists, from the days of the Greeks, and then to the leading figures of the Renaissance or the pioneers of modern physics talked with each other using mathematics. Today, investigations in the most advanced (i.e., well-codifi

As we have seen, the general application of ordinary algebraic rules entails various sorts of mathematical elements, such as imaginary numbers and quaternions. Accordingly, it also entails variations on the effects and validity of preestablished arithmetical operations and notions. As suggested earlier, we might be able to dispose of all such complications if we could somehow change the rules that lead to the "existence" of imaginary expressions. And there is but one rule th

TYPE TERMINOLOGY Every field has its own jargon or vocabulary. It is important to learn the terminology in order to appear more knowledgeable when communicating with a client, another designer, or a printer. The term serif and sans serif are used when referring to type. Serifs are appendages, or little feet, found on the tops and bottoms of Roman letters. It is assumed that they were derived either from the chisel marks left after letters were cut into stone or from the brus

COMPLEX CORTEX The cerebral cortex is the largest part of the human brain. Its multiple folds allow more cortical tissue to fit inside the skull. The cortex carries out the brain's most complex information processing, and its massive expansion in humans is elemental to the sophistication of human intelligence. Divisible into over 50 regions, each with a unique internal organization and different connections to other brain regions, the cortex is conventionally divided into fou

80/20 Rule A high percentage of effects in any large system are caused by a low percentage of variables.1 The 80/20 rule asserts that approximately 80 percent of the effects generated by any large system are caused by 20 percent of the variables in that system. The 80/20 rule is observed in all large systemss, includeing those in economics, management, user interface design, quality control, and engineering, to name a few. The specific percentages are not important, as measur

There are two important color models to be aware of. Here is the briefest of explanations on a very complex topic. If all you ever do is print to your little desktop color inkjet, you can get by without knowing anything about color models, so you can skip this for now. It will be here when you need it. CMYK CMYK stands for Cyan (which is a blue), Magenta (which is sort of red/pink), Yellow, and a key color, which is usually black. With these four colors of ink, we can print m

IF ONE LOOKS AR THE SKY on a clear, moonless night, the brightest objects one sees are likely to be the planets Veunus, Mars, Jupiter, and Saturn. There will also be a very large number of stars, which are just like our own sun but much farther from us. Some of these tixed staars do, in fact, appear to change very slightly their positions relative to each other as the earth orbits around the sun: they are not really fixed at all! This is because they are comparatively near to

There was almost certainly a genetic contribution to Einstein's dopaminergic traits. One of his two sons became an internationally reconized expert on hydraulic engineering. The other was diagnosed with schizophrenia at the age of twenty, and died in an asylum. Large population studies have also found a genetic componet of a dopainergic character. An Icelandic study that evaluated the genetic profile of ver 86,000 people discovered that individuals who carried genes that plac

God, grant me the serenity To accept the things I cannot change Courage to change things I can And wisdom to know the difference. THE SERENITY PRAYER has been adopted by Alcoholics Anonymous and other organizations that help members recover from addiction. It reveals why the brain fascinates people so much: They are always hoping to change it. Just stroll through the self-help section of your local bookstore -- you'll see hundreds of titles on how to drink less, quit drugs

Imagine taking a bird's-eye view of your neighborhood. You notice that some people take their dogs for a walk every morning at six o'clock. Others don't get out with their canienes until nine. Others stroll their pooches after lunch. Others opt for nighttime walks. If you watched the dynamics of the neighborhood for a while, you'd notice that people in the neighborhood who happen to walk at the same time tend to become friends with one another: they bump into one another, the

"Kenneth Olsen, the engineer who founded and still runs Digital Equipment Corp., confessed at the annual meeting that he can't figure out how to heat a cup of coffee in the company's microwave oven." You Would Need an Engineering Degree to Figure This Out "You would need an engineering degree from MIT to work this," someone once told me, shaking his head in puzzlement over his brand new digital watch. Well, I have an engineering degree from MIT. (Kenneth Olsen has two of them

"Color pick from your palette, not your painting Whenever you mix two colors, the resulting color will be less pure, so unless you are working with solid brushes without pressure sensitivity, your strokes will never present your selected color in its hundred percent opaque state. Considering this you will find that continueously color picking from within your painting will desaturate your colors more and more, until you are left with bland representations of your actual palet
