Digital Compositing for Film and Video


Book Description

Digital Compositing for Film and Video is a hands-on, practical, how-to guide that addresses the problems and difficult choices faced by the professional compositor in real-life situations. It presents techniques, tricks, and solutions for dealing with badly shot elements, coloration artifacts, and mismatched lighting that bedevil actual compositors working on real shots. Readers are offered in-depth practical methods for matte extraction, despill procedures, compositing operations, and color correction--the "meat and potatoes" of all digital effects. Compositing is the artistic blending of several disparate elements from a variety of sources into a single image while making all the component elements appear to be in the same light space and shot with the same camera. When confronted with a bad composite any observer will recognize that something is wrong--the artist will know what is causing the problem, and the technician will know how to fix it. A good compositor must be both an artist and a technician. Written by a senior compositor with over ten years' experience in both feature film and broadcast television, this book offers a broad range of alternative solutions that will save hours of fiddling with composites trying to get them to look right when the basic tools aren't working. A companion CD-ROM provides examples of the many topics covered in this book.







Imaging of Trabecular Microfracture and Bone Marrow Edema and Hemorrhage


Book Description

This excellently illustrated monograph summarizes the updated fresh information on the theoretical, practical, and rapidly extended facets of gamma correction 99mTc-hydroxymethylene diphosphonate pinhole bone scan (99mTc-GCPBS) to MRI, CR, and MDCT. Basically, 99mTc-GCPBS is able to precisely visualize and quantitate callused trabecular microfracture (CTMF) which is as little as 200 μm in size. The extended gamma correction images can very neatly demonstrate CTMF on MRI, conventional radiography (CR), and multidetector computed tomography (MDCT). Whenever appropriate, histological correlation is provided in conjunction with fine gamma corrected images. In this setting, ACDSee 10 gamma correction MRI and CR have been found to offer a highly useful option that deserves wider clinical interest. In practice, gamma correction MRI, CR, and MDCT can distinctly visualize CTMF so that CTMF can be precisely measured simply using an optic lens. By comparison, the naïve MRI, for example, shows CTMF which measures as big as 2 mm in size. Furthermore, 99mTc-GCPBS can now differentiate bone marrow edema from hemorrhage using the visuospatial mathematic method, which includes the ImageJ of the NIH.
