Applications of Complex-Logarithmic Conformal Mapping in Still Image Coding
This paper evaluates the performance of an image compression system based upon the complex logarithmic conformal mapping. A staple in the robotics and visual systems fields, our attempts were to investigate the application of this algorithm in the field of image compression. The characteristics predisposed to the log sensor include a foveal region centered around the focal point which generates...
متن کاملSubjective Evaluation of Hevc Intra Coding for Still Image Compression
High Efficiency Video Coding (HEVC) demonstrates a significant improvement in compression efficiency compared to H.264/MPEG-4 AVC, especially for video with resolution beyond HD, such as 4K UHDTV. One advantage of HEVC is the improved intra coding of video frames. Hence, it is natural to question how such intra coding compares to state of the art compression codecs for still images. This paper ...
متن کاملHigh-quality Speech Coding
Kei Kikuiri, Nobuhiko Naka and Shinya Abe The high-quality speech coding is a super-wideband speech coding technique for providing high-quality VoIP services in a high-speed wireless communication environment, and was developed in collaboration with DoCoMo Communications Laboratories USA, Inc. This technology encodes and transmits nearly all of the frequency components of the human voice to all...
متن کاملThe JPEG2000 still image coding system: an overview
With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the specific area of still image encoding, a new standard is currently being developed, the JPEG2000. It is not only intended to provide rate-distortion and subjective image quality performance superior to existing standards, but also to provide feat...
متن کاملRobust still image coding using lapped transforms with block classification
Very efficient still image compression methods exist today, but most of them are not fit for transmission on error prone channels. One example of state-of-the-art robust image coding is the use of wavelet compression followed by forward error correction (FEC), as proposed by Sherwood and Zeger, that gives high coding efficiency but suffers from the incomplete decoding problem. An alternative to...
