Graph matching (GM) is a fundamental problem in computer science, and it plays a central role to solve correspondence problems in computer vision. GM problems that incorporate pairwise constraints can be formulated as a quadratic assignment problem (QAP). Although widely used, solving the correspondence problem through GM has two main limitations: (1) the QAP is NP-hard and difficult to approximate; (2) GM algorithms do not incorporate geometric constraints between nodes that are natural in computer vision problems. To address aforementioned problems, this paper proposes factorized graph matching (FGM). FGM factorizes the large pairwise affinity matrix into smaller matrices that encode the local structure of each graph and the pairwise affinity between edges. Four are the benefits that follow from this factorization: (1) There is no need to compute the costly (in space and time) pairwise affinity matrix; (2) The factorization allows the

This is a plugin script for Go-ogle"s free 3D design program Sketchup. The free version of Sketchup has limited file export options and many CAM programs will not recognise the native Sketchup (SKP) file format. This plugin allows you to export your Sketchup model as a DXF or STL files readable by most CAM and 3D printer software.Using the pluginAfter copying this file, start Sketchup and you should now have an extra menu option (Export to DXF or STL) in the Sketchup Tools menu.There are five export options:STL  triangles. Use this for Makerbot or Reprap style 3D printersDXF polyface mesh. This will give the most faithful reproduction of your original Sketchup model.DXF polylines: exports the outlines of each face as a polyline, sometimes useful for CAM toolpaths.DXF triangular mesh: breaks all the faces up into trianglesDXF lines.
