You can download the paper, the code, and the RGBD image dataset, and the web image dataset.

Given an initial graph template and a set of attributed relational graphs (ARGs), this method modifies the graph template into the common subgraph pattern among the ARGs with the MAXIMAL graph size, by discovering probably missing nodes, deleting redundant nodes, and training the attributes.

Extented Application 1: As a platform of category modeling from cluttered scenes, this technique has been applied to train category models for 3D reconstruction from ubiquitous images.

Extented Application 2: Recovering the model for the whole object from a fragment using cluttered (web) images.

Given a set of cluttered scenes (web images) that contain objects in the target category, this technique can be applied to recover the category model from “an object fragment”.
