Free Download Shape from Positional-Contrast: Characterising Sketches with Qualitative Line Arrangements By Björn Gottfried (auth.)
2007 | 214 Pages | ISBN: 3835060708 | PDF | 2 MB
Graphical queries for the purpose of searching for pictorial information are of growing interest in areas where pictures provide valuable information, including, for instance, design, architecture, and engineering. Sketching graphical queries is a natural way of revealing the visual appearance of objects one has in mind. Björn Gottfried develops computationally effective concepts for dealing with shape, in particular imprecise and incomplete sketched shapes. He exemplarily applies his method using graphical queries to search for historical objects. Specifying objects graphically, he shows that the new method is in fact capable of dealing with imprecise sketches. Generally speaking, the notion of positional-contrast is introduced. It defines how patterns can be robustly dealt with. That is, the new representation distinguishes patterns by how they relate with regard to spatial relations. This notion can be applied for several purposes, including pattern recognition, motion analysis, and texture analysis.

Free Download Siavash Mazdeyasna, Chong Huang, "Near-infrared Speckle Contrast Diffuse Correlation Tomography for Noncontact Imaging of Tissue Blood Flow Distribution"
English | 2022 | ISBN: 1032133872 | PDF | pages: 67 | 3.8 mb
Imaging of tissue blood flow (BF) distributions provides vital information for the diagnosis and therapeutic monitoring of various vascular diseases. The innovative near-infrared speckle contrast diffuse correlation tomography (scDCT) technique produces full 3D BF distributions. Many advanced features are provided over competing technologies including high sampling density, fast data acquisition, noninvasiveness, noncontact, affordability, portability, and translatability across varied subject sizes. The basic principle, instrumentation, and data analysis algorithms are presented in detail. The extensive applications are summarized such as imaging of cerebral BF (CBF) in mice, rat, and piglet animals with skull penetration into deep brain. Clinical human testing results are described by recovery of BF distributions on preterm infants (CBF) through incubator wall, and on sensitive burn tissues and mastectomy skin flaps without direct device-tissue interactions. Supporting activities outlined include integrated capability for acquiring surface curvature information, rapid 2D blood flow mapping, and optimizations via tissue-like phantoms and computer simulations. These applications and activities both highlight and guide the reader as to the expected abilities and limitations of scDCT for adapting into their own preclinical/clinical research, use in constrained environments (i.e., neonatal intensive care unit bedside), and use on vulnerable subjects and measurement sites.

Free Download High Contrast: Race and Gender in Contemporary Hollywood Films By Sharon Willis
1997 | 280 Pages | ISBN: 0822320290 | PDF | 19 MB
In High Contrast, Sharon Willis examines the dynamic relationships between racial and sexual difference in Hollywood film from the 1980s and 1990s. Seizing on the way these differences are accentuated, sensationalized, and eroticized on screen-most often with little apparent regard for the political context in which they operate-Willis restores that context through close readings of a range of movies from cinematic blockbusters to the work of the new auteurs, Spike Lee, David Lynch, and Quentin Tarantino.Capturing the political complexity of these films, Willis argues that race, gender, and sexuality, as they are figured in the fantasy of popular film, do not function separately, but rather inform and determine each other’s meaning. She demonstrates how collective anxieties regarding social difference are mapped onto big budget movies like the Die Hard and Lethal Weapon series, Basic Instinct, Fatal Attraction, Thelma and Louise, Terminator 2, and others. Analyzing the artistic styles of directors Lynch, Tarantino, and Lee, in such films as Wild at Heart, Pulp Fiction, and Do the Right Thing, she investigates how these interactions of difference are linked to the production of specific authorial styles, and how race functions for each of these directors, particularly in relation to gender identity, erotics, and fantasy.

Free Download Contrast-Enhanced Ultrasound in Pediatric Imaging by Paul S. Sidhu
English | EPUB | 2021 | 292 Pages | ISBN : 3030496902 | 120.6 MB
This book is a comprehensive guide to the rapidly evolving field of contrast-enhanced ultrasound (CEUS) in the child. The uses and interpretation of CEUS are clearly explained with the aid of numerous illustrations. The coverage encompasses both established indications, such as focal liver lesions, abdominal solid organ injury, and vesicoureteral reflux, and a range of newer applications. Extensive information is also provided on microbubble agents and their use in the pediatric age group, as well as on practical aspects of setting up a CEUS service for children.

Free Download Atlas of Contrast-enhanced Sonography of Focal Liver Lesions by Tommaso Vincenzo Bartolotta , Adele Taibbi , Massimo Midiri
English | PDF (True) | 2015 | 150 Pages | ISBN : 3319175386 | 19.4 MB
This book offers an image-based, comprehensive quick reference guide that will assist in the interpretation of contrast-enhanced ultrasound (CEUS) examinations of the liver in daily practice. It describes and depicts typical and atypical behavior of both common and less frequently observed focal liver lesions. For each type of lesion, the findings on pre- and post-contrast images are presented and key characteristics are highlighted. Individual chapters also focus on the assessment of response to locoregional and systemic treatment and the impact of European guidelines on CEUS. The Atlas of Contrast-Enhanced Sonography of Focal Liver Lesions will serve as an invaluable hands-on tool for practitioners who need to diagnose liver lesions using CEUS in the major clinical settings: oncology patients, cirrhotic patients, and patients with incidental focal liver lesions.
