中文摘要：

本文提出了一种适合矩不变特性的球虫卵囊图像的预处理算法，并基于改进的变形雅克比-傅立叶矩，分别对同-虫卵的不同图像和不同球虫卵囊图像进行理论计算和对比实验发现，同一种球虫卵囊的不变矩值分布具有很好的一致性，而不同种类球虫卵囊的不变矩值分布又具有很好的区别性，基于该预处理方法对巨型艾美尔球虫卵囊的尺度、平移、旋转等多畸变图像进行计算，各矩值标准偏差很小，说明该方法可以很好地提高不变矩在图像识别中的可用性和准确性。

英文摘要：

a new preprocessing algorithm, which improve the invariance quality of the modified Pseudo - Jacobi - Fourier moments, is presented in this paper, different images of the same eggs and oocysts images were calculated and compared with the experimental findings, invariant moments a coccidian oocysts values are consistent good distribution, and invariant moments of different coccidia oocysts value dis- tribution and has very good, to calculate the pretreatment method of E. maxima oocysts scale, translation, rotation and distortion image based on, the moment value standard deviation is small, it shows that the method can greatly improve the usability and the accuracy of in- variant moment in image recognition.
