The metric is based on initial work from the group of Professor C.-C. Jay Kuo at the University of Southern California. [1] [2] [3] Here, the applicability of fusion of different video quality metrics using support vector machines (SVM) has been investigated, leading to a "FVQA (Fusion-based Video Quality Assessment) Index" that has been shown to outperform existing image quality metrics on a ...
Carl Zeiss Meditec AG is a multinational medical technology company and subsidiary of Carl Zeiss AG. It manufactures tools for eye examinations and medical lasers as well as solutions for neurosurgery, dentistry, gynecology and oncology. Among its products are the most common tools used by ophthalmologists and optometrists.
Video quality is a characteristic of a video passed through a video transmission or processing system that describes perceived video degradation (typically compared to the original video). Video processing systems may introduce some amount of distortion or artifacts in the video signal that negatively impact the user's perception of the system.

The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
The Sony Zeiss Vario-Tessar T* FE 24-70mm F4 ZA OSS is a constant maximum aperture full-frame (FE) zoom lens for the Sony E-mount, announced by Sony on October 16, 2013. [ 1 ] [ 2 ] Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 36 ...
The Contaflex series is a family of 35mm Single-lens reflex cameras (SLR) equipped with a leaf shutter, produced by Zeiss Ikon in the 1950s and 1960s. The name was first used by Zeiss Ikon in 1935 for a 35mm Twin-lens reflex camera, the Contaflex TLR; for the earlier TLR, the -flex suffix referred to the integral reflex mirror for the viewfinder.
Learning effect: new patients improve as more tests are performed due to understanding of the test conditions. Consider the third test as the baseline result [23] Potential for artefacts (i.e. uncharacteristic vision loss) (fig. 6). Below is a list of possible artefacts and a representation of how they may appear.
