in order to obtain and implement the interpolation with high quality and efficiency, and high reliable segmentation algorithms with the minimization human interaction in the medical image sequence, interpolators and segmentation are studied in the paper 论文分析了医学图像插值和分割技术,提出并实现了质量高效率好的插值算法和医学图像序列可靠性高的最小化用户交互分割算法。
nc machining requires " interpolation " algorithms that accurately and efficiently generate sequences of reference position, distributed according to a prescribed feedrate function, along the tool paths . this paper present a systematic derivation of the proper taylor series coefficients for variable feedrate interpolators . when the path is ph curves, detailed formulations for instances are presented where the feedrate v is specified as a constant, the function of the time t, the arc length s and the local curvature k 对于nc加工要求插值算法沿着刀具路径准确、有效的生成参考点序列(根据预先指定的速率函数进行分布)的实际工程需要,本文系统地推导了变速率插值算子的泰勒系数,给出了当路径为ph曲线,速率v为常数,及时间t、弧长s、曲率k的函数时具体的插值算子。
