Contact Information: Author(s): Sathwika Bavikadi E-mail: [email protected] Venkata Bharath Botta E-mail: [email protected] Supervisor: Irina Gertsovich University Examiner: Dr. Sven Johansson Department of Applied Signal Processing Internet : www.bth.se Blekinge Institute of Technology Phone : +46 455 38 50 00 SE–371 79 Karlskrona, Sweden Fax : +46 455 38 50 57 Abstract Images, unlike text, represent an effective and natural communica- tion media for humans, due to their immediacy and the easy way to understand the image content. Shape recognition and pattern recog- nition are one of the most important tasks in the image processing. Crime scene photographs should always be in focus and there should be always be a ruler be present, this will allow the investigators the ability to resize the image to accurately reconstruct the scene. There- fore, the camera must be on a grounded platform such as tripod. Due to the rotation of the camera around the camera center there exist the distortion in the image which must be minimized. -

Photography: a Survey of New Reference Sources
RSR: Reference Services Review. 1987, v.15, p. 47 -54. ISSN: 0090-7324 Weblink to journal. ©1987 Pierian Press Current Surveys Sara K. Weissman, Column Editor Photography: A Survey of New Reference Sources Eleanor S. Block What a difference a few years make! In the fall 1982 issue of Reference Services Review I described forty reference monographs and serial publications on photography. That article concluded with these words, "a careful reader will be aware that not one single encyclopedia or solely biographical source was included... this reviewer could find none in print... A biographical source proved equally elusive" (p.28). Thankfully this statement is no longer valid. Photography reference is greatly advanced and benefited by a number of fine biographical works and a good encyclopedia published in the past two or three years. Most of the materials chosen for this update, as well as those cited in the initial survey article, emphasize the aesthetic nature of photography rather than its scientific or technological facets. A great number of the forty titles in the original article are still in print; others have been updated. Most are as valuable now as they were then for good photography reference selection. However, only those sources published since 1982 or those that were not cited in the original survey have been included. This survey is divided into six sections: Biographies, Dictionaries (Encyclopedias), Bibliographies, Directories, Catalogs, and Indexes. BIOGRAPHIES Three of the reference works cited in this survey have filled such a lamented void in photography reference literature that they stand above the rest in their importance and value. -

An Ironic Manifesto Jeffrey Baker Pamela Petro Formerly & Hereafter by Zeb Andrews by Dr. Mike Ware Tina Maas Sika Stanton Plates to Pixels Juried Show Praise for Diffusion, Volume I “Avant-garde, breakthrough and innovative are just three adjectives that describe editor Blue Mitchell’s first foray into the world of fine art photography magazines. Diffusion magazine, tagged as unconventional photography delivers on just that. Volume 1 features the work of Jeffrey Baker, Pamela Petro, Tina Maas and Sika Stanton. With each artist giving you a glimpse into how photography forms an integral part of each of their creative journey. The first issue’s content is rounded out by Zeb Andrews’ and Dr. Mike Ware. Zeb Andrews’ peak through his pin-hole world is complimented by an array of his creations along with the 900 second exposure “Fun Center” as the show piece. And Dr. Mike unscrambles the history of iron-based photographic processes and the importance of the printmaker in the development of a fine art image. At a time when we are seeing a mass migration to on-line publishing and on-line magazine hosting, the editorial team at Diffusion proves you can still deliver an outstanding hard-copy fine art photography magazine. I consumed my copy immediately with delight; now when is the next issue coming out?” - Michael Van der Tol “Regardless of the retrospective approach to the medium of photography, which could be perceived by many as a conservative drive towards nostalgia and sentimentality. -

The Development and Growth of British Photographic Manufacturing and Retailing 1839-1914
The development and growth of British photographic manufacturing and retailing 1839-1914 Michael Pritchard Submitted for the degree of Doctor of Philosophy Department of Imaging and Communication Design Faculty of Art and Design De Montfort University Leicester, UK March 2010 Abstract This study presents a new perspective on British photography through an examination of the manufacturing and retailing of photographic equipment and sensitised materials between 1839 and 1914. This is contextualised around the demand for photography from studio photographers, amateurs and the snapshotter. It notes that an understanding of the photographic image cannot be achieved without this as it directly affected how, why and by whom photographs were made. Individual chapters examine how the manufacturing and retailing of photographic goods was initiated by philosophical instrument makers, opticians and chemists from 1839 to the early 1850s; the growth of specialised photographic manufacturers and retailers; and the dramatic expansion in their number in response to the demands of a mass market for photography from the late1870s. The research discusses the role of technological change within photography and the size of the market. It identifies the late 1880s to early 1900s as the key period when new methods of marketing and retailing photographic goods were introduced to target growing numbers of snapshotters. Particular attention is paid to the role of Kodak in Britain from 1885 as a manufacturer and retailer. A substantial body of newly discovered data is presented in a chronological narrative. In the absence of any substantive prior work this thesis adopts an empirical approach firmly rooted in the photographic periodicals and primary sources of the period. -

This is an examination of the developing understanding and control of water in South Africa, as well as the societal impacts that control had on a conflicted society. It examines the responses to water in the early twentieth century, being a foundation period that sets up later water concerns in the following decades, and the period from the 1990s to the present, as a time of change in water use. ater in South Africa is central to the struggles of the country. Since the earliest days of human habitation in South Africa, water has defined where people live, how they survive, what they eat, and why they move. -
Forensic Photography 2
Forensic Photography: Concepts and Applications Tuesday, January 8, 13 What Is It? Police Photography, Forensic Photography, Evidence Photography, Crime Scene Photography, Accident Photography …..? Forensic Photography is the fair and accurate recording of a scene or object, of legal interest, by a camera. “For the police photographer, photographs are statements of what he or she saw at a scene (Miller, p.9).” Tuesday, January 8, 13 Review of the Literature “Photography is a valuable tool for recording the crime scene and explaining the evidence to others.” (Staggs, p. 8). “The objectives of crime scene photography are to record the conditions of the scene before alteration, record the location and position of evidence items collected, document the point of view of principals and potential witnesses, and document spatial relationships of pertinent items.” (Ogle, p. 3). Tuesday, January 8, 13 From Mr. Henry Lee, et.al. The purpose of crime scene photography is to provide a visual record of the scene and related areas; to record the initial appearance of the crime scene and physical evidence; to provide investigators and others with the permanent record subsequent (sic) analysis of the scene; and to provide the permanent record to the court…crime scene photography is one of the most important steps in the entire investigation process. As one of the primary documentation components, systematic, organized visual record of an undisturbed crime scene must be achieved (Lee, et. al., pp. 80-81).” Tuesday, January 8, 13 A Few Basic Rules Do not disturb the scene: Photograph the scene as is before putting in scales and placards (Becker, p. -
Use of Scangraphy for Computer Visualization of Handwritten Text Shading
FORENSIC PRACTICE Krystyn Łuszczuk, M.Sc. Eng. IT specialist, member of the Polish Forensic Association Mieczysław Goc, Ph.D. (corresponding author) Professor at the WSB University in Gdańsk, Deputy President of the Polish Forensic Association Andrzej Łuszczuk, M.Sc. Document expert at the Polish Forensic Association Use of scangraphy for computer visualization of handwritten text shading Summary The article indicates the importance of computer programs as tools supporting the handwriting expertise and increasing its objectivity. Some of these programs are based on computer scangraphy. Scangraphy is a handwriting examination method in which a text sample is treated as a raster image (a bitmap), i.e. a set of single (dots) pixels. The bitmap pixel pattern can be tested in a variety of different ways, as required. The article describes the first computer program to use scangraphy in handwriting examination. Key words: scangraphy, handwriting, computer handwriting scans, SCANGRAF Introduction of expert opinions, particularly vivid in the doctrine Studies on handwriting are mainly based on qualitative and American jurisprudence, not always favorable to methods. Quantitative methods, consisting of different the handwriting expertise, often classifying it as the types of measurements, instrumental analyses and so-called non-scientific evidence, has led, on the one statistical calculations, which guarantee high precision hand, to the development of criteria for the admissibility and repeatability of results, have a minor usage. Due to of such evidence in court proceedings2, and, on the limited role of measurements in handwriting expertise, other hand, to the initiation of studies on the actual subjective evaluation of test results by an expert is of state of handwriting expertise, including the relevant key importance1. -
