| Abstract(in English) | Fourier descriptor, which extracts shape characteristics of plain curves, has an ability of approximating an original curve by reconstruction using low-frequency components. Although the Fourier descriptor is originally defined forcontinuous curves, several methods of its discretization have been proposed since practical image processing treats quantized curves. The influence of the quantization is large for small objects. In this paper, the influence of the discretizations investigated by comparing the quantization methods experimentally, in the case of describing elementary small objects in a texture. The result sggests thatggests that the P- and Z-descriptors, which consider the curvature, are superior to the G-descriptor, which regards a discretized curve as a point sequence. |
