But the existing CCD cannot satisfy the practical needs. Therefore several pieces of CCD which has insufficient pixels are spliced to get a long CCD array with plenty of pixels. The precision requirements of CCD splicing are very strict  so that the same high accuracies are required in the precision detection of CCD splicing. When detecting precision of CCD splicing  the graphical markers with simple geometric structure in the CCD package are selected as templates. The position precision data of the graphical markers in each CCD are obtained using the template matching algorithm. Using the unified objective templates  the focal plane which has multi-chip of CCD is detected by template matching algorithm. Experiment results show that the template matching algorithm can enhance the located precision of each CCD to 0.347m. The splicing precision detection with template matching algorithm can avoid the subjective error caused by the conventional detection method. And its results are more accurate. In addition  without manual intervention in the process of precision detection  the efficiency of precision detection is improved. 2011 IEEE.   Effective image splicing detection based on image chroma 会议论文  OAI收割 IEEE International Conference on Image Processing, Cairo, 2009 作者:  Wang, Wei;  Dong, Jing;  Tan, Tieniu 收藏  |  浏览/下载：9/0  |  提交时间：2016/10/24 image splicing detection  image chroma
