In theory, every problem of involving morphological analysis and examination can be solved with digital image processing technology. Because there are irregular form structures, uncertain space positions and impure samples of the human helminth eggs, digital application and research is underdeveloped in parasitology. The recognition and analysis of human helminth eggs is unable to be performed by means of automatic instrument as blood cell. As a result, they have been observed and distinguished under the microscope through the naked eye for a long time.

从理论上说，凡是牵涉到形态分析和检测的问题都可以用数字图像处理技术来解决，但由于人体寄生虫虫卵的不规则的形态结构、空间方位和标本杂质较多等原因，数字图像技术在寄生虫学上的应用和研究很少，寄生虫虫卵的识别无法象血细胞分析一样用自动化仪器进行，长期以来只能依赖人眼在显微镜下进行观察分辨。
