Surfel_FILE_COMPRESSION
- 针对点云数据局部集中的特点,使用差值预测对点云数据进行预测处理 在预测的同时,根据IEEE2754 浮点数标准,简化浮点数的尾数,使用3. 5 Byte来表示一个浮点数,以提高压缩效果 然后对预测数据中连续重 复的字节使用该字节加该字节重复的次数的方式存储 最后对经过以上处理的数据使用一阶自适应算术编码进 行压缩。最终得到的程序在压缩比和内存占用两个方面远优于WinRAR、WinZip压缩软件-Point cloud data for the characteristics of l

lossless-image-compression-based-on-optimal.pdf.z
- The optimal predictors of a lifting scheme in the general n-dimensional case are obtained and applied for the lossless compression of still images using rst quincunx sampling and then simple row-column sampling. In each case, the e ciency of the
Adaptive-Turbo-Trellis-Coded-Modulation
- In this contribution, we propose an adaptive Turbo Trellis Coded Modulation (TTCM) aided Distributed Space-Time Trellis Coding (STTC) scheme for cooperative communication over quasi-static Rayleigh fading channels.
Kite-Codes
- Kite codes, which were originally defined over the binary field, are generalized to arbitrary abelian groups in this paper. Kite codes are a special class of prefix rateless codes over groups, which can generate potentially infinite (or as many
