Szukana fraza: [Abstrakt = "The paper presents the algorithm for recognizing and locating high voltage power lines with the use of horizontal images. The algorithm has the highest sensitivity to horizontal edges and at the same time is insensitive to vertical edges. The first stage includes an edge detection algorithm. The second stage involves filtering of detected edges and classifying the points for further analysis. Using gradient method, the regions containing noise or background are discarded. The final classification of pixels representing the line is made using the longest path detection algorithm. In the third stage a shape of the wire is approximated based on the set of selected points. Then the contour of the detected wire is constructed with a set of pixels representing interrupted paths, thus increasing the accuracy of the final approximation."]
