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

介绍了前向线性预测滤波算法的基本原理,提出了一种自适应滤波过程中各参数的确定方法,对某硅微陀螺的静态
漂移信号和实际动态信号进行了处理,给出了静态漂移信号滤波前后的Allan 方差和标准差的大小,对滤波前后的误差大小
和误差分布进行了分析,并与小波中值滤波效果进行了比较。结果表明,前向线性预测滤波方法无论是在去噪效果,还是实
时性等方面,都明显优于小波中值滤波-Principle of t he forward linear prediction ( FL P) is int rod

文中提出了一种基于kalman 预测和自适应模板的目标相关跟踪算法。通过kalman 预测下一帧图像中目标的
状态,缩小整个图像上目标检测的搜索范围,满足目标跟踪的实时性。采取自适应模板更新策略,根据目标的变化情
况自动调节参考模板,提高目标跟踪的稳定性。仿真实验结果表明,算法能够随着目标的形状、大小、位置的变化快速
调整参考模板,进行稳定和实时的跟踪,当目标被物体遮挡时仍能有效地跟踪目标。-A correlation-based tracking algorithm based o
