在数据合并的时候很方便，因为 CONSTRUCT图中的谓词不一定和原图中的相同。
This can come in handy during data merging because the predicates used in the CONSTRUCTed graph are not required to be the same as the ones in the original graph.
若因此会误期或使价格增加，则只能按买方原来书面要求采用原图纸、数据和其他技术资料。
If additional delay or cost is involved, such drawings, data and other technical information shall only be used upon the written request of the Purchaser.
指正式测井图。输入全部有关的测井图头数据之后，打印在优质图纸上，常常作为长期保存的测井记录。正式图件和现场原图相对应。
The permanent print of a well log made on high-quality paper with appropriate heading information and calibration. Final print is in contrast to field print.
栅格格式数据转换为矢量格式数据时必须提取原图像上包含的拓扑信息。
Is is necessary to abstract the topology information from preprocessed image while converting grid data into vector data.
零水印是不对原图像数据进行修改的一种新的数字水印技术。
Zero watermark is a new digital watermarking technology without modifying the data of original image.
已有的数字水印方法为了嵌入水印信息都对原图像数据采用各种方法或多或少地进行了修改，这样做使其鲁棒性和安全性受到限制。
In the existing method of digital watermark, for embedding watermark information, authors modify more or less original image data through various methods to limit its robustness and security.
图像融合把来自多个传感器数据的互补信息合成一幅新的图像，提供比原图像更丰富的视觉信息。
With the help of complementary data information of multisensor, a new image is reconstructed by image fusion, which provides richer visual information than the original images.
因此，需在保持原图像中包含的本质信息的基础上，对通信和存储时必需的数据进行压缩。
Therefore, the need to maintain the original image information contained in the basis of the nature of communications and the need to store compssed data.
在梯形校正中，将所得到的RGB图像数据进行插值运算后再进行梯形转换，并将得到的梯形图形与原图形进行了对比。
In trapezoid correction, the obtained RGB data was calculated by trapezoid transforming after image interpolation, and made the contrast of the trapezoid image with the source image.
