Abstract: Locating the telephone number region is a very important technology in telephone number recognition of the fax images. After realizing a relative precise page analysis on the fax images by adopting the Connected Component Analysis (CCA) to form comparatively whole word regions, the features of horizontal traversing times and spatial distribution were abstracted to form feature vector of fifty-one dimensions. The multi-class Support Vector Machine (SVM) based on normal decision tree was introduced to achieve the key words location. The experimental results show that the method can realize the location quickly and effectively, and it is valuable in applications.

Key words: Connected Component Analysis (CCA), horizontal traversing times, spatial distribution feature, Support Vector Machine (SVM), key words location
