Line detection based on Euclidean distance


Abstract:
To detect lines in digital image, this paper proposed a new algorithm. Different form traditional line detection algorithms, the algorithm does not search another coordinate transformation, but defines the line degree of a point in a curve as the sum of k Euclidean distance square between points centered at the point, and deduces that except limited points in the head and tail, points in a line segment will have the maximum line degree. Derived from this characteristic, the new algorithm detects line segments in a two-pass manner. Firstly, the points on a curve that obviously belonged to a line segment were selected by using Freeman chain-code. Secondly, the points that were continuous and had the maximum line degree were selected. The result shows the algorithm is stable, precise and fast.
