The aim of the work is to develop and research a method for recognizing static palm gestures using
complex contour analysis. The use of complex contour analysis involves the solution of several problems -
the selection of palm contours, piecewise linear approximation of the contours, the calculation of the autocorrelation
function (ACF) of the resulting contour, comparison of the ACF of the contour with the ACF of
the reference contour. Algorithms are presented that implement each stage of palm image processing, and
the results of experimental studies of the method on a large series of palm gestures
Key words: contour detection, gradient detection methods, piecewise linear approximation, autocorrelation
function of a contour, criterion for the proximity of contours.
