The goal of this book is to show how usability metrics can be a powerful tool for
successfully evaluating the user experience for any product. When some people
think about usability metrics, they feel overwhelmed by complicated formulas,
contradictory research, and advanced statistical methods. We hope to demystify
much of the research and focus on the practical application of usability metrics.
We’ll walk you through a step-by-step approach to collecting, analyzing, and
presenting usability metrics.
Visual quality assessment is an interdisciplinary topic that links image/video processing, psychology and physiology. Many engineers are familiar with the image/video processing; transmission networks side of things but not with the perceptual aspects pertaining to quality. Digital Video Quality first introduces the concepts of human vision and visual quality. Based on these, specific video quality metrics are developed and their design is presented. These metrics are then evaluated and used in a number of applications, including image/video compression, transmission and watermarking.
Soybean is the most important oilseed and livestock feed crop in the world. These dual uses are attributed to the crop's high protein content (nearly 40% of seed weight) and oil content (approximately 20%); characteristics that are not rivaled by any other agronomic crop. Across the 10-year period from 2001 to 2010, world soybean production increased from 168 to 258 million metric tons (54% increase).
