The discrete wavelet transform has remarkable multi-resolution and energy-compaction properties. Amir-Homayoon Najmi's introduction to wavelet theory explains this mathematical concept clearly and succinctly. \u003c\/p\u003e\u003cp\u003eWavelets are used in processing digital signals and imagery from myriad sources. They form the backbone of the JPEG2000 compression standard, and the Federal Bureau of Investigation uses biorthogonal wavelets to compress and store its vast database of fingerprints. Najmi provides the mathematics that demonstrate how wavelets work, describes how to construct them, and discusses their importance as a tool to investigate and process signals and imagery. He reviews key concepts such as frames, localizing transforms, orthogonal and biorthogonal bases, and multi-resolution. His examples include the Haar, the Shannon, and the Daubechies families of orthogonal and biorthogonal wavelets.\u003c\/p\u003e\u003cp\u003eOur capacity and need for collecting and transmitting digital data is increasing at an astonishing rate. So too is the importance of wavelets to anyone working with and analyzing digital data. Najmi's primer will be an indispensable resource for those in computer science, the physical sciences, applied mathematics, and engineering who wish to obtain an in-depth understanding and working knowledge of this fascinating and evolving field.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Amir-Homayoon Najmi\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1421404966\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781421404967\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Johns Hopkins University Press\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 03\/20\/2012\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 304\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.92lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.10h x 6.00w x 1.00d","brand":"Amir-Homayoon Najmi","offers":[{"title":"Paperback","offer_id":48449574109439,"sku":"9781421404967","price":50.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_8861a7cb-ae73-4ea9-a654-c35753e4e743.jpg?v=1777263991","url":"https:\/\/www.whiterainbookhouse.com\/products\/wavelets-amir-homayoon-najmi-9781421404967","provider":"WR Book House","version":"1.0","type":"link"}
