The pre-processing process is to use a mathematical calculation method, a filter, or a database to differentiate outlines of objects and to classify different objects of the image data. Then different colors, which are in the outlines of the different objects, are acquired by using a color classifying method and the different colors are used to be different characteristic values of the image data.
