TWO APPROACHES TO THE SELECTION AND VECTORIZATION OF COUNTOR LINES OF OBJECTS OF THE UNDERLYINS SURFACE
This article presents a formulation of the problem of combining images situation of the aircraft cabin and the virtual terrain model obtained on the digital map of the area, to create a combined system (improved / synthesized) vision are specific and the main features of these types of images. A review of existing methods for solving the subproblem selection and vectorization of contour lines, a method considered luminance edge detection algorithm underscore boundaries and tracing on the basis of identified their strengths and weaknesses. Describes the main stages of the proposed methods, identified their strengths and weaknesses. Presented a modified method of Otsu. The algorithm for thin lines. A comparison of the proposed methods on five parameters, recommendations for their further use for solving the problem of combining disparate images.
