Ultra-High-Definition Mapping of Atrial Arrhythmias.
The advantages of ultra-high-definition (UHD) mapping are presented in the context of different atrial arrhythmias, whether focal or macroreentrant. Not only are these sophisticated systems time-saving, but they also allow accurate identification of the substrate (scar quantification), as well as a more precise characterization of the critical isthmuses or focal sources of the atrial circuits. ...
متن کاملAudiovisual focus of attention and its application to Ultra High Definition video compression
Using Focus of Attention (FoA) as a perceptual process in image and video compression belongs to well-known approaches to increase coding efficiency. It has been shown that foveated coding, when compression quality varies across the image according to region of interest, is more efficient than the alternative coding, when all region are compressed in a similar way. However, widespread use of su...
متن کاملUltra-High-Definition Television and Its Optical Transmission
Super Hi-Vision’ (SHV) is promising as a future form of television. It is an ultra-high definition TV system that has 16 times the number of pixels of HDTV and employs a 22.2 multichannel sound system. It offers superior presence and gives the impression of reality. The information bitrates of the current prototypes range from 24 to 72 Gbit/s, and a fiber optic transmission system is needed to ...
متن کاملResearch on Architecture Design for Ultra High Definition Video Encoding
I-Abstract Ultra high definition (UHD) video includes 4K (3840×2160) and 8K (7680×4320, also known as super Hi-vision) formats. By delivering 4 and 16 times of pixels per frame compared to today's high definition (1920x1080), UHD videos offers remarkably enhanced visual experience and provides rich cues for stereoscopic feeling such as visual field angle, linear perspective, and texture gradien...
متن کاملUltra-high definition (8K UHD) endoscope: our first clinical success
BACKGROUND We have started clinical application of 8K ultra-high definition (UHD; 7680 × 4320 pixels) imaging technology, which is a 16-fold higher resolution than the current 2K high-definition (HD; 1920 × 1080 pixels) technology, to an endoscope for advanced laparoscopic surgery. RESULTS Based on preliminary testing experience and with subsequent technical and system improvements, we then p...
