目的 该文是关于中国图像工程的年度文献综述系列之十九。为了使国内广大从事图像工程研究和图像技术应用的科技人员能够较全面地了解国内图像工程研究和发展的现状，能够方便地查询有关文献，且向期刊编者和作者提供有用的参考，对2013年度图像工程重要文献进行了综述分析。方法 从2013年在国内15种有关图像工程重要中文期刊的共140期上所发表的2 986篇学术研究和技术应用文献中，选取出716篇属于图像工程领域的文献，并根据各文献的主要内容将其分别归入图像处理、图像分析、图像理解、技术应用和综述5个大类，然后进一步分入23个专业小类（与前8年相同），并在此基础上分别进行了各期刊各类文献的统计和分析。结果 根据统计分析结果可看出：图像分割仍然是图像分析中的一个焦点与难点，具有很强的挑战性；对图像真实性的鉴别与完整性的修复近期得到越来越多的关注；基于图像技术的人体生物特征的研究还需要新的动力；遥感、雷达、测绘等领域代表了2013年图像工程科技应用的最大热点。结论 该工作表明2013年中国图像工程的研究和应用有了许多新的进展，展现出一些新的发展特点和趋势。

Objective This is the nineteenth in the annual survey series of the yearly bibliographies on image engineering in China. The purpose of this survey work is mainly to capture the up-to-date development of image engineering in China, to provide a convenient means of literature searching facility for readers working in related areas, and to supply a useful reference for the editors of journals and potential authors of papers. Method Considering the wide distribution of related publications in China, 716 literatures on image engineering are selected carefully from 2986 research and application papers published in 140 issues of a set of 15 Chinese important journals related to image engineering. Those selected literatures are classified first into 5 categories(image processing, image analysis, image understanding, technique application and survey), and then into 23 specialized classes according to their main contents(same as the last 8 years). Some analysis and discussions about the statistics made on the results of classifications by journal and by category are also presented, respectively. Result According to the statistics and analysis on the results, it seems that image segmentation is still a focus and critical point in image analysis, and has strong challenging; identification of image authenticity and inpainting for image integrity get more and more attentions recently; the research on human biometrics based on image techniques requires some new pushing force; and the domains of remote sensing, radar as well as survey and draw are the hottest field for technology applications of image engineering in 2013. Conclusion This work shows a general and off-the-shelf picture of the various progresses of image engineering research and application with some new developing characteristics and tendencies in China in 2013.
