Contour Determination and Shape Characteristics of Different Varieties of Potato Tubers
Popis výsledku v původním jazyce
The work summarizes the results of quantification of shape variability of ten different varieties of potato tubers produced in the Czech Republic. The elliptic Fourier descriptors were chosen as a mathematical descriptive tool. The image analysis and following mathematical processing revealed that first principal component (which represents height to width ratio) is a very useful and applicable measure of the total shape variation. It represents 70.58--74.02 % of the total shape variation (front-view) for Karin and Vendula varieties respectively. Not significantly different results were obtained for other two analyzed views -- side-view and top-view. Four main principal components account for nearly 100 % of the total variance in both, front and side-view shape and 97 % in top-view shape. The common problem, which must be faced on when evaluating a small shape variations is solved by using elliptic Fourier descriptors and principal component analysis, because this procedure is highly a
