A color map processing system PU-CMPS

A color map processing system PU-CMPS (color map processing system of Peking University) is introduced. The main functions of PU-CMPS are color-separating, segmentation, vectorizing, recognizing, and automatic editing. First, PU-CMPS strips each kind of color from the original color map. Then, segmentation is implemented to separate the character (including number and small graphic symbols), dash line, point, and solid region. After thinning, a new scanline vectorizing algorithm converts the raster images into vector images. On the vector version of images, a class of recognizing algorithms which is based on fuzzy synthesis analysis is developed to classify the graphic structures on the images. Several automatic editing algorithms are also developed to remove the noises and connect the broken lines. It is proved by experiments that all these algorithms are highly efficient
