Recognizing and Extracting of Rivers in Colorful Map

Na Wang

Abstract— The method of recognizing and extracting the rivers in colorful map is studied. There is a binary extracted method to be proposed: based on gray image, and there are some related problem to be introduced, for example: gray convert, binary, thinning and vectorization. Through the study, there is result that this method is not only simple and fast, but also is able to realize the process of binary when the rivers are extracting. At last, this extracted method is used to the certain area map, and obtains the good experiment result.

Index Terms— river extraction, gray convert, binary, thinning, vectorization.
