Fax image layout analysis based on connect components
基于连通区域的传真图像版面分割与分类算法

In order to improve accuracy of layout segmentation and classification of fax images,segment images by merging horizontally/vertically adjacent connect components blocks by setting threshold properly.And combined image classify process with image segment process,obtained matrix based on connect components.Then,abstracted the feature vector of eight dimensions for representing block information.And classified document images as two types with BP artificial neural networks.In experiments,the accuracy of layout segmentation and classification was 89.2% and 94.22%.Experimental results show that the method is effective and feasible in document images segmentation.
