             abstract = "We propose a new approach for segmenting a document image into its 
                         page components (e.g. text, graphics and tables). Our approach 
                         consists of two main steps. In the first step, a set of scores 
                         corresponding to the output of a convolutional neural network, one 
                         for each of the possible page component categories, is assigned to 
                         each connected component in the document. The labeled connected 
                         components define a fuzzy over-segmentation of the page. In the 
                         second step, spatially close connected components that are likely 
                         to belong to a same page component are grouped together. This is 
                         done by building an attributed region adjacency graph of the 
                         connected components and modeling the problem as an edge removal 
                         problem. Edges are then kept or removed based on a pre-trained 
                         classifier. The resulting groups, defined by the connected 
                         subgraphs, correspond to the detected page components. We evaluate 
                         our method on the ICDAR2009 dataset. Results show that our method 
                         effectively segments pages, being able to detect the nine types of 
                         page components. Furthermore, as our approach is based on simple 
                         machine learning models and graph-based techniques, it should be 
                         easily adapted to the segmentation of a variety of document
