Efficient Super-Resolution Up-Conversion Algorithm for HDTV
نویسندگان
چکیده
Video up-conversion takes significant place in various application areas. One of important application areas is standard-definition television (SDTV) video processing to get high-definition television content (HDTV) for broadcast. However, high-quality upconversion is a challenging task. Most practical implementations use spatial domain processing such as video frame interpolation for video up-scale. Meanwhile, due to sampling limitation the highfrequency component of output HD video cannot be efficiently reconstructed by applying only the spatial domain processing and high-quality up-conversion usually requires temporal domain processing as well. The authors propose practical implementation of such up-conversion technique providing significantly better visual results in comparison to traditional methods of SDTV to HDTV up-conversion.

Subjective assessment of HDTV with superresolution function
Super Resolution (SR) has become common, and some recent HDTV sets and digital cameras are equipped with it. SR is a sales point of commercial products. However, the resolution of HDTV sets equipped with an SR function has not been tested as to whether it is actually better than those of HDTV sets without the function, in part because the resolution difference between HDTV sets is not always cl...
متن کاملContent-Adaptive Video Up-Scaling
The introduction of High Definition Television (HDTV) asks for spatial up-conversion techniques in order to enable the displaying of standard definition material (SDTV). Recently, X. Li and M. Orchard proposed the “New Edge-Directed Interpolation” (NEDI) algorithm for high quality up-scaling of natural images. In this paper, we first analyze and evaluate this technique, and then propose a numbe...
متن کاملHDTV transmission format conversion and migration path
The development of high-definition television (HDTV) in the United States has recently resulted in the establishment of a national standard for its coding and transmission. This standard dictates, among other specifications, certain limitations on the allowable resolution of transmitted HDTV signals. There are many of these allowable formats, permitting scene-dependent processing and encoding; ...

Video resolution enhancement takes important place in various application areas. One of significant application areas is standard-definition (SD) video processing to get high-definition (HD) content for television and broadcast. However, due to many reasons high-quality up-conversion is still a challenging task. We can overcome this using stereo camcorder. The author propose practical super-res...
متن کامل4K-to-8K TV Up-converter with Super Resolution
The 8K system is intended to be the ultimate high-resolution broadcasting system. However, 8K equipment is still under development, and there will be a lack of 8K content once broadcasting begins. It would thus be very useful if 4K content could be converted to a sufficient resolution level to be viewed on 8K systems. Conventional up-converters, from SDTV to HDTV, change the video format with i...
