Abstract：To deal with the problems of overall labeling of connected characters and low labeling efficiency in the recognition of power engineering drawings,a connected component labeling algorithm based on mathematical morphological dilation and simplified decision tree was proposed in the work.The structural elements,which could be flexibly set up,were employed to dilate the input image and further to realize the overall labeling of the connected characters.Through the analysis of various possibilities of the adjacent pixels,an efficient connected component labeling algorithm based on simplified decision tree was designed,thus improving the recognition efficiency of power engineering drawings.The simulation results show that the as-proposed algorithm can significantly improve the execution efficiency when achieving the overall labeling of connected characters in comparison with the traditional methods,and its execution time is about half that of the traditional methods.
