Questões e gabarito - ITA 2007


(Ita 2007) (...)For about 25 years, I have had the opportunity to observe the efforts of many individuals applying digital image-processing techniques to problems offered by the real world. A few of these individuals have established an enduring track record of solid success on almost every attempt. They have consistently contributed innovative and effective solutions that creatively employ the tools of the discipline.These highly productive individuals demonstrably hold several characteristics in common. One can 1venture to assume that these characteristics constitute a formula for success, to whatever extent such a thing can exist in this field.Uniformly, these successful persons have (1) a genuine interest in - even a fascination with - the technology involved, (2) a thorough understanding of the fundamentals of this highly multidisciplinary technology, (3) a conceptual type of understanding (4as opposed to rote memorization of totally abstract theory), and (4) a 2knack for seeing problems visually, graphically, and from more than one viewpoint. 5In line with this last point, they often find themselves hard 3pressed to explain their ideas without the aid of a graph or drawing.This book is designed to help the reader develop the last three of these traits and perhaps enhance the first as well. The selection of materials for inclusion (and, equally important, for omission), the examples used, the references cited, and the exercises and suggestions for projects are all directed toward this goal.In the field of digital image processing, mathematical analysis forms the stable basis upon which one can make definite predictions regarding the performance of a digital imaging system. In this treatment, 6however, mathematics is employed more as a faithful servant than as a ruthless master. The emphasis is on developing a conceptual understanding, and the analysis is used to support this goal. Castleman, K. R. Digital Image Processing.
