Methods for Acquiring Geometrical Properties in an Image Employed for Determining Image Stereo-Correspondence

In the paper the evaluation of algorithms for determining graph vertices on the basis of binary images is presented. The covered algorithms employ the classic contour detection method as well as the Hough transform and the MPPM (minimum perimeter polygon method). The presented algorithms are the basis for image matching and determining the stereo correspondence of images. Stereo-pairs were acquired from a system for diagnosing faulty posture using the photogrammetric method. The algorithm operation is analyzed for the image matching technique that uses the optimal clique finding method.
