search region meaning in Chinese
搜索区域
Examples
- The difficulty existing in stereo matching is how to eliminate the mismatching , and the effective means is reducing the search region
立体匹配中的难点是消除歧义匹配,有效的办法是缩小搜索范围。 - The possible position of moving target center in the next frame image was predicted by kalman filter , and a search region of target was generated
该方法利用卡尔曼滤波预测目标中心在下一帧图像中可能出现的位置，以该位置为中心，建立候选的目标搜索区域。 - Final , the plane models producing method for complete plane regions is proposed involving limiting the search region of extending for a half - plane , extending region with feature points , grouping neighbor and coplanar planes and rendering the plane models
最后，提出建构出完整平面模型的方法，包括半平面扩展的搜寻范围限制，使用特徵点来进行平面扩展，将邻近且共平面的两平面组合起来，绘制出平面模型。 - Some analyses of data feature in urban aerial image are done first , and a split - block - clustering based on fcm method is discussed for the coarse segmentation of building groups , which can reduce the search region for buildings extraction and decrease calculation much more
首先分析了城市航空影像数据特点，并利用分块fcm聚类方法对建筑群进行预分割，从而缩小了在航空影像数据中建筑物提取的搜索空间，大大较少了计算量。 - In this paper , two important modifications in dct - based coding algorithm are suggested after making deep study on the generally used scheme of h . 263 coder . first , we find plenty of invalid computation in the transformation part of the h . 263 coder and an improved scheme based on the pre - transform decision to avoid invalid computation is proposed . second , in the motion estimation part of the coder , we find that normal search algorithms are not effective , which neglects different levels of motion in image sequences , and we suggest a new search algorithm which has variable search region based on the difference of motion level . combining the pre - transform decision scheme with variable search region method in motion estimation , a global decision coding scheme is provided , which greatly increases the coding speed of h . 263 coder
本文对h . 263编码算法的现有实现方法作了深入的分析，首先发现变换部分存在大量无效运算，提出了在变换前加判决的前变换判决的编码方案，以压缩无效的变换运算；其次发现运动估计部分由于忽略了图像场景的分级运动而存在一定的无效搜索运算，提出了基于分级运动的可变搜索域法来压缩无效的搜索运算；最后将前变换判决方案与运动估计的可变搜索域法有机地结合在一起，提出了全局判决编码方案，从而比较全面地改进了现有实现方法，因而能大幅度地提高编码器的编码速度
