代码说明:

   本文主要做了1.对三维重建系统中的预处理算法和分割算法进行细致研究,并通过大量实验进行对比分析,指出其优缺点及适用围。 2.传统的分割算法处理每一幅图片都需要用户选定对象和背景,耗时较长。针 对医学CT连续断层图像间相关性强特点,提出一种把Graph Cut方法和区域生长方法相结合的图像分割算法。3.最后将分割目标与后续重建算法结合起来,建立一个完整的三维重建系统。 (This paper has 1 of 3D reconstruction system of preprocessing and segmentation algorithm is carefully studied, and through a lot of experiments are compared and analyzed, and points out their advantages and disadvantages and application range. 2 traditional segmentation algorithm to deal with each picture requires the user to select the object and background, time-consuming. For medical CT images correlation strong characteristic, put forward a segmentation algorithm combining Graph Cut method and region growing method. 3 finally the target segmentation and subsequent reconstruction algorithms are combined, the establishment of a complete 3D )

    JTIDS是16号数据链的通道系统,本文主要是对在脉冲干扰的情况下16号链的波形性能分析!(The Link-16 is the tactical data link utilized by the Joint Tactical Information Distribution Syste (JTIDS). The JTIDS system is important due to its wide use by U.S. armed forces, NATO, and other allied militaries. Link-16 is a hybrid frequency-hopped/direct sequence spread spectrum system that utilizes minimum-shift keying (MSK) to modulate the chips, cyclical code-shift keying (CCSK) to modulate the 32-chip symbols, and a (31, 15) Reed Solomon (RS) code with hard decision decoding (UDD) for forward error correction (FEC).)
