Haar (fog)
In meteorology, haar or sea fret is a cold sea fog. It occurs most often on the east coast of Scotland between April and September, when warm air passes over the cold North Sea. The term is also known as ''harr'', ''hare'', ''harl'', ''har'' and ''hoar''. Causes Haar is typically formed over the sea and is blown to the land by the wind. This commonly occurs when warmer moist air moves over the relatively cooler North Sea causing the moisture in the air to condense, forming haar. Sea breezes and easterly winds then bring the haar into the east coast of Scotland and North-East England where it can continue for several miles inland. This can be common in the UK summer when heating of the land creates a sea breeze, bringing haar in from the sea and as a result can significantly reduce temperatures compared to those just a few miles inland. Nomenclature The term ''haar'' is used along certain lands bordering the North Sea, primarily eastern Scotland and the north-east of England ...

Haar (Westphalia)
The Haar () or Haarstrang is a ridge of hills on the southern edge of the Westphalian Basin in the German state of North Rhine-Westphalia. From a natural region perspective it is the southern, submontane part of the Hellweg Börde, which stands opposite the northern area of the Süder Uplands (which is the natural region of the Sauerland), north of the Möhne and Ruhr rivers.E. Meynen and J. Schmithüsen: ''Handbuch der naturräumlichen Gliederung Deutschlands'' - Bundesanstalt für Landeskunde, 6th edition Remagen 1959 (a total of 9 editions in 8 books 1953-1962, updated in 1960 with 1:1,000,000 map of major landscape units) Its highest elevation is the 391 m high ''Spitze Warte'', which is situationed near Rüthen- Hemmern at the eastern end of the Haarstrang. Further west the crest of the ridge reaches heights of generally 200 to 250 m above sea level ( NN) and rises to about 100 to 150 m over the Ruhr and Möhne valleys in the south as well as the valley of the Lippe in th ...

Alfréd Haar
Alfréd Haar (; 11 October 1885, Budapest – 16 March 1933, Szeged) was a Kingdom of Hungary, Hungarian mathematician. In 1904 he began to study at the University of Göttingen. His doctorate was supervised by David Hilbert. The Haar measure, Haar wavelet, and Haar transform are named in his honor. Between 1912 and 1919 he taught at Franz Joseph University in Cluj-Napoca, Kolozsvár. Together with Frigyes Riesz, he made the University of Szeged a centre of mathematics. He also founded the ''Acta Scientiarum Mathematicarum'' journal together with Riesz. Biography Haar was born to a Hungarian-Jewish''Transcending Tradition: Jewish Mathematicians in German Speaking Academic Culture'', Birgit Bergmann, (Springer 2012), page 63 family in Budapest on 11 October 1885 to parents Ignác Haar and Emma Fuchs.

Haar Wavelet
In mathematics, the Haar wavelet is a sequence of rescaled "square-shaped" functions which together form a wavelet family or basis. Wavelet analysis is similar to Fourier analysis in that it allows a target function over an interval to be represented in terms of an orthonormal basis. The Haar sequence is now recognised as the first known wavelet basis and is extensively used as a teaching example. The Haar sequence was proposed in 1909 by Alfréd Haar. Haar used these functions to give an example of an orthonormal system for the space of square-integrable functions on the unit interval , 1 The study of wavelets, and even the term "wavelet", did not come until much later. As a special case of the Daubechies wavelet, the Haar wavelet is also known as Db1. The Haar wavelet is also the simplest possible wavelet. The technical disadvantage of the Haar wavelet is that it is not continuous, and therefore not differentiable. This property can, however, be an advantage ...

Haar Measure
In mathematical analysis, the Haar measure assigns an "invariant volume" to subsets of locally compact topological groups, consequently defining an integral for functions on those groups. This Measure (mathematics), measure was introduced by Alfréd Haar in 1933, though its special case for Lie groups had been introduced by Adolf Hurwitz in 1897 under the name "invariant integral". Haar measures are used in many parts of mathematical analysis, analysis, number theory, group theory, representation theory, mathematical statistics, statistics, probability theory, and ergodic theory. Preliminaries Let (G, \cdot) be a locally compact space, locally compact Hausdorff space, Hausdorff topological group. The Sigma-algebra, \sigma-algebra generated by all open subsets of G is called the Borel algebra. An element of the Borel algebra is called a Borel set. If g is an element of G and S is a subset of G, then we define the left and right Coset, translates of S by ''g'' as follows: * Left ...

Haar-like Feature
Haar-like features are digital image features used in object recognition. They owe their name to their intuitive similarity with Haar wavelets and were used in the first real-time face detector.Viola and Jones,Rapid object detection using a boosted cascade of simple features, Computer Vision and Pattern Recognition, 2001 Working with only image intensities (i.e., the RGB pixel values at each and every pixel of image) made the task of feature calculation computationally expensive. A publication by Papageorgiou et al. discussed working with an alternate feature set based on Haar wavelets instead of the usual image intensities. Paul Viola and Michael Jones adapted the idea of using Haar wavelets and developed the so-called Haar-like features. A Haar-like feature considers adjacent rectangular regions at a specific location in a detection window, sums up the pixel intensities in each region and calculates the difference between these sums. This difference is then used to categorize s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
