此文是关于中国图象工程的度度文献综述系列之四。考虑到目前我国图象工程的研究，图象技术的应用和有关文献的分布情况，我们查看了1998年发表在国内15种有关图象工程重要中文期刊上的近1400多篇学术研究和技术应用论文，并从中选出300多篇根据其主要内容进行了分类和统计，

This is thefourth in the survey series of yearly bibliographies on image engineering in China.Considering the current status of the researches on image engineering and the applications ofimage techniques as well as the distribution of related publications in China,more than 300 research and technique references are selected from near 1500 research papers published in a set of 15 Chinese journals,in which papers concerning image engineering are relatively concentrated.These references are classified into different categories according to their contents.An analysis and a discussion of thestatistics made on the classification results are also presented.This work shows a general and up-to-date picture of the progresses of image engineering in China,supplies a convenient means of literature searching for readers doing researches and/or applications in this field,and provides auseful reference for the editors of journals and potential authors of papers.
