Contour Following Using Maximum Search Algorithm

Abstract

In this paper we are generating a gray gradient image with clearly visible object edges and without branches(e.g. letter”B” = 3 objects O1, O2, O3, use image”text.bmp”), then we are determining the contour lines of the objects as lists of pixel coordinates and of contour codes (including start pixels). We are using maximum search, starting with 3directions, further moving into 5 and 7 directions whenever required.
