Evaluation of shape variability of stallion sperm heads by means of image analysis and Fourier descriptors

Popis výsledku v původním jazyce

Quantification and evaluation of stallion sperm shape variability was performed. Sperms of 10 different stallions were tested. Length to width ratio, position of the center of gravity, curvature, and degree of roundness were considered. The procedure used for this task was based on the elliptic Fourier descriptors. The scores of the components were used in subsequent analysis as sperm head shape characteristic. The variation in shape accounted for by each component was visualized using inverse Fourier transformation. The first four principal components provide a good summary of the data, accounting for 88.46 -- 92.33 % of the total variance. Dominant importance and relevance of length to width ratio (with contribution of 48.63 -- 53.48 % to the total variance) as a determining parameter of sperm head shape was quantitatively confirmed.
