FIELD: physics, computer engineering.
SUBSTANCE: invention relates to means of selecting linear objects on images. The method comprises processing an image using a finite impulse response (FIR) filter, which enables to determine points belonging to extended linear objects on the image from the positive response of the FIR filter, based on analysis of mean-square deviation values of brightness of points of the filter window when the filter window is turned relative to each analysed point on the image.
EFFECT: high accuracy of selecting extended linear objects on an image.
