扫描顺序 meaning in Chinese
scanning sequence
Examples
- Discontinuities in the scanning sequence are indicative of a hardware failure that must be corrected before use
扫描顺序中断表示必须在使用之前纠正硬件故障。 - In order to guarantee the validity of this algorithm , firstly the characteristic of an image is extracted , then the frame is divided into several blocks . in each block feature points are chosen to estimate the motion vectors according to certain scanning order
为了保证该算法的有效性，先提取图像的特征，再采用分区的方法在各个分区内按一定的扫描顺序选取灰度最大值点作为特征点用于运动矢量的估计。 - There is no motion compensation in the proposed scheme , so the method is simple and can be easily implemented in hardware . through the optimization of the quantization volume and scanning order , the 3d - dct based video coding scheme can obtain satisfactory results both in compression ratio and in psnr
3d - dct变换编码，没有运动补偿，运算复杂度低，通过优化量化表和扫描顺序，使3d - dct达到了令人满意的压缩比和图像质量。 - In this paper ， an optimal search strategy by dividing the whole surveillance area into regions is presented so that the optimal search can be adaptively implemented in phased array radar . firstly ， the inherent relationship among average discovering time ， radar resources consumption ， search frame period and target distribution density is studied . secondly ， parameters for the region search are optimized to achieve the optimal search performance inside regions . then ， the optimal search frame period for each region is derived to minimize the average discovering time of targets ， where the constraint of radar time resource and the importance of each region are taken into account . finally ， the adaptability of this search strategy is discussed . only if the optimal parameters for each region are utilized and the beams are scheduled according to the optimal frame period under the radar time constraint ， the optimal distribution and the optimal scanning sequence of beams can be implemented adaptively . thus ， optimal search is adaptively implemented in the whole surveillance area
本文提出一种分区搜索算法，实现了相控阵雷达的自适应最优搜索.首先，研究了各区域平均发现一个目标消耗的雷达资源和目标被发现的平均时间同搜索帧周期以及目标强度的关系；然后，研究了在各区域采用两步搜索算法的最优参数设计，实现了局部区域的最优搜索；其次，在雷达时间资源有限和区域重要性加权的约束条件下，导出了使目标被发现的平均时间最小的区域最优帧周期；最后，讨论了分区搜索算法的自适应性.只要采用各区域的最优参数，按最优帧周期调度雷达波束，就可以自适应地实现使目标被发现的平均时间最短的波束的最优分布和扫描顺序，即自适应最优搜索 - When the hid file is a image , common image process will affect the attracted information if we hide the hid image into the original image by its own scan order . so we scramble the hid image before it is embedded to the original image . here we use the baker transposition to scramble the hid information to get better attracted image
针对待隐藏文件为图像的情况，由于直接按待隐藏图像的扫描顺序将其嵌入原始图像中时，在嵌入信息后的图像经过图像处理后会对提取信息的质量影响比较大，因此本文提出了一种隐藏算法，考虑在嵌入信息之前对待隐藏图像进行预处理，将待隐藏图像进行置乱。
