What is Digital Raster Graphic A digital raster graphic (DRG) is a digital image resulting from scanning a paper USGS topographic map for use on a computer. DRGs created by USGS are typically scanned at 250 dpi and saved as a TIFF. The raster image usually includes the original border information, referred to as the "map collar". The map file is UTM projected and georeferenced to the surface of the Earth. DRG's are regularly used in GIS applications. DRGs were first produced in 1995.

Lossless Information Hiding in Images introduces many state-of-the-art lossless hiding schemes, most of which come from the authors' publications in the past five years. After reading this book, readers will be able to immediately grasp the status, the typical algorithms, and the trend of the field of lossless information hiding. Lossless information hiding is a technique that enables images to be authenticated and then restored to their original forms by removing the watermark and replacing overridden images. This book focuses on the lossless information hiding in our most popular media, images, classifying them in three categories, i.e., spatial domain based, transform domain based, and compressed domain based. Furthermore, the compressed domain based methods are classified into VQ based, BTC based, and JPEG/JPEG2000 based. - Focuses specifically on lossless information hiding for images - Covers the most common visual medium, images, and the most common compression schemes, JPEG and JPEG 2000 - Includes recent state-of-the-art techniques in the field of lossless image watermarking - Presents many lossless hiding schemes, most of which come from the authors' publications in the past five years
This book talks about developing and improvising upon medical presentations by equipping readers with critical technical tips and tricks to use popular presentation programs like PowerPoint or Keynote effectively. The book details numerous remedial measures for qualitative improvement of average medical presentations. It has three sections: first covers the general aspects of preparing a presentation; the second provides practical details and refinements of preparing a medical presentation; the last section deals with niceties of podium and webinar presentations. The chapters cover many serious mistakes and remedial measures to improve average medical presentations, such as a description of purposeful use of colors in a slide, a brief discourse on technicalities of appropriate clinical image formats for projection ensues; the use of drawing and photo-editing programs to inject excellence in the contents of a medical presentation to help it stand out in the crowd, details on the importance of lexical correctness- typography, line spacing and alignment to enhance the impact of the presented text and many more. Several short videos support and actively promote the viewpoints discussed in the text. This book elaborates on the exquisite art of creating remarkable medical presentations for a specialized audience. This book is a must-have for all healthcare professionals of all specialties and grades who make podium presentations in a medical conference webinar or submit posters for display.
The Encyclopedia of Image Processing presents a vast collection of well-written articles covering image processing fundamentals (e.g. color theory, fuzzy sets, cryptography) and applications (e.g. geographic information systems, traffic analysis, forgery detection). Image processing advances have enabled many applications in healthcare, avionics, robotics, natural resource discovery, and defense, which makes this text a key asset for both academic and industrial libraries and applied scientists and engineers working in any field that utilizes image processing. Written by experts from both academia and industry, it is structured using the ACM Computing Classification System (CCS) first published in 1988, but most recently updated in 2012.
