Original abstract

This contribution describes the problem of the analysis of Fourier descriptors method for picture processing and a proposal of the programme system for solving digital filtering especially with the regard to the selection of suitable filters for the arrangements of picture matrix in robotics, in the noise suppression, the accentuation of contours in lithography, etc. The definition of Fourier descriptors of curve k has been introduced here. The paper contains a comparison of Fourier analysis of closed curves with other orthogonal transformations. Requests for an optimum orthogonal base for curve classification according to their descriptors have been also determined here. In the conclusion the possibilities of using Fourier descriptors method have been outlined.

Czech abstract

Tento příspěvek popisuje problém analýzy metody Fourierova popisu pro zpracování obrazu a návrh programového systému pro řešení digitální filtrace s ohledem na vhodné filtry pro uspořádání matice obrazu v robotice, k potlačení šumu, k zdůraznění obrysů v litografii apod. V příspěvku je uvedena definice Fourierova popisu křivky. Příspěvek obsahuje porovnání Fourierovy analýzy uzavřených křivek s jinými ortogonálními transformacemi. Je také uvažován požadavek na optimální ortogonální bázi pro klasifikaci křivek vzhledem k jejich popisu. V závěru jsou načrtnuty možnosti užití metody Fourierova popisu.
