Binary image to Finite element mesh ( GMSH geo file )

This code creates GMSH geo file from an image boundary that can be readily meshed using GMSH.

This short code calculates boundary of a binary image and forms a surface using spline function. Then a short geo file is written which when executed in GMSH , meshes the domain of the original image with features defined by the color contrasts. Here a simple image of OM symbol is taken and converted into a geo file. The output mesh.txt is the geo file to be executed in GMSH.
