1) block repetition definition
块的重定义
1.
This paper introduces the operation and skill of application of block in AutoCAD to simplify mechanical drawing,including the reasonable use of the property block,the block repetition definition and so on.
介绍了应用AutoCAD的块来简化机械绘图的操作方法和技巧,包括合理利用属性块、块的重定义等。
2) domain block
定义域块
1.
The searching computation of the best matched domain block is most heavy in the fractal encoding process.
在分形编码过程中 ,搜索值域块的最佳匹配的定义域块的计算量最大。
2.
In fractal block coding, the one by one matching procedure between the range block and the domain block in a pool of domain blocks is extremely time-consuming.
在分形块编码中，值域块与定义块池中的定义域块逐一匹配过程极其费时，为了大大地缩短分形编码的时间，将定义域块和值域块的匹配限制在以值域块的均值和方差作为中心的动态窗口中。
3.
In fractal coding, the matching procedure between the range block and domain block in a pool of domain blocks one by one is time consuming.
将多尺度分析的思想引入到值域块与定义域块匹配过程中，预先剔除掉在粗尺度下与值域块不匹配的定义域块，相对减少了在细尺度下与值域块匹配的定义域块。
3) the domain block
定义域块
1.
According to the feature that the domain block is in one-to-one correspondence with the least mean square error (LMSE) in fractal coding, a multi-pose-and-expression face retrieval method is proposed in this paper.
利用图像分形编码中定义域块和最小均方误差一一对应的特点 ,提出了 1种基于分形编码的多姿态、表情的人脸图像检索方法。
6) macro definition block
宏定义块
