In this review, we outline the principles upon which retinal digital image analysis is based. We discuss current techniques used to automatically detect landmark features of the fundus, such as the optic disc, fovea and blood vessels. We review the use of image analysis in the automated ...

The difference between land and landscape is that landscape implies human perception and the representation people make of it. People sense and experience their environment holistically, using all senses simultaneously. Gestalt-principles apply here. Various disciplines study landscape perception and the men...
Medical imaging: applying principles of physical phenomena (like radiation) to data processing to generate an image The Future of Bioengineering Biomedical engineers continue to push the boundaries of medical science, developing newer and better methods for salvaging human life. While biologists focus on...
In photography, we often talk about zones (derived from Ansel Adams’ zone system). A zone is a range of illumination L that varies by a factor of two, i.e., if the lower and upper boundaries of a zone are L1 and L2, then L2 /L1 = 2 or log2(L2)– log2(L1) = 1. 1 2 ...
Good design can’t be achieved with glossy buttons or masterful wireframes alone. It’s a merger of all these principles into something that is meaningful and deliberate.Our Services We Are Here For You When you choose to do business with us you are partnering with a company who cares. We...
observed. If the observer is looking straight down (normal view), the apparent depth is calculated using the refractive index. However, when viewed at an angle, the apparent depth can seem even shallower due to the change in the angle of refraction, following the principles of Snell’s law....
Although Uber's proposal relies on the existing technologies and NASA UTM proposal, it does present a discussion about the principles of designing urban airspace, especially in terms of social acceptance, which is not odd given that Uber's success relies on the positive acceptance of its users....
The main Gestalt principles of visual perception are: Similarity:The human eye will build a relationship between similar elements in a design. Using basic elements such as shapes, colors, and size is an effective way. Shows similarities based on shape, size and color. Image creditInteraction-Des...
2) The Subject of modern photogrammetry? Preface Preface The practice of photogrammetry today bears little resemblance to that during its formative years in the last century. While the basic mathematical principles of photogrammetry remain unchanged, their implementation and application for production ...
