UGU is a small geometry library which implements camera, image, mesh, etc.

• in : texture-less mesh, camera parameters, (predefined UV on the mesh, optional)
• out: textured mesh

• Comparizon table

• PatchMatch Stereo
  • in : rectified left and right image pair
  • out: disparity, cost, plane image, left right consistency mask, and depth (if baseline and intrinsics are avairable)
  • Speed: approx. 90 sec. with post-process for middlebury dataset third size (463 * 370)

• in : mesh, camera parameters
• out: color, depth, normal, mask and face id

color	depth

normal	mask	face id

  • To pull dependencies registered as git submodule.
• Use CMake with CMakeLists.txt.
  • reconfigure.bat and rebuild.bat are command line CMake utilities for Windows 10 and Visual Studio 2017.
