Abstract:

The present study was undertaken to compare and analyze the microscopic characteristics of helminth eggs of ruminants, such as cattle and sheep, and realize the digital description of helminth egg images. Nine kinds of identified helminth were selected for obtaining abundant eggs from cloaca in this study. To establish helminth egg images database, the mature eggs were selected and photographed by biological microscope. The sizes and shapes of all helminth eggs were compared and the Pseudo-Jacobi-Fourier Moments were used for feature extraction and digital description. The result showed that, the length and width of different helminth eggs all have significant differences, the invariant moment values of the same kind of eggs were almost the same, but different kinds of eggs revealed large difference in the invariant moment values. The reconstruction images of the helminth eggs is satisfied, and they are much similar to original images, hence, the PJFM’s is suitable to extract the key feature point of eggs images. Therefore, our study can provide important technologic basis for digitization description and intellegent identification of helminth eggs.
