IEEE International Conference on Image Processing
作者: Hiuk Jae Shim Jinhaeng Ahn Byeungwoo Jeon School of Information and Computer Engineering Sungkyunkwan University Suwon South Korea
LZW is one of the well-known lossless compression methods. Since it has several remarkable features such that coding is simple, prior analysis on source is unnecessary, and the whole code table is not sent to its deco... 详细信息

IEEE International Conference on Consumer Electronics (ICCE)
作者: Hongli Fei Huazhong Tsinghua University Beijing Beijing CN
To reduce the external memory cost, an efficient 5/3-DWT based embedded compression algorithm is proposed for H.264 decoder. Decoded frames are decomposed into 4×4 blocks which are then compressed into 32-bit or ... 详细信息

IEEE (first ITW conference of the year) Information Theory Workshop (ITW)
作者: G. Caire S. Shamai A. Shokrollahi S. Verdu Institut Eurecom Technion EPFL Princeton University USA
This paper proposes a universal variable-length lossless compression algorithm based on fountain codes. The compressor concatenates the Burrows-Wheeler block sorting transform (BWT) with a fountain encoder, together w... 详细信息

Biomedical Engineering International Conference (BMEiCON)
作者: Phinitnan Chanasabaeng Boonying Charoen Jarin Paphangkorakit Department of Electrical Engineering Faculty of Engineering Khon Kaen University Khon Kaen Thailand Department of Oral Biology Faculty of Dentistry Khon Kaen University Khon Kaen Thailand
For long-term electromyographic (EMG) signal acquisition, data compression can be used to reduce the original data to a smaller size. This reduction decreases the bandwidth and energy used during transmission. Storing... 详细信息
