Apply some kinds of diffusion algorithms for inpainting 2D or 3D grids.

Note

Only for 2d depth image (16bit) now. But it is easy to be extended to gray scale image or RGB image.

Building Instruction

Dependencies

• OpenCV 3.+
• CMake 3.14+
• Eigen

• Note: Eigen is not necessary but you need to delete some dependent codes if you do not install Eigen. All related codes are declared under Eigen namespace

Usage

Drawing mask: ./diffu_inpainting draw [input img path] [output mask path]

Heat Diffusion: ./diffu_inpainting heat [number of iteration (int)] [time step (float)] [input img path] [mask path] [output img path]

Anisotropic Diffusion: ./diffu_inpainting anisotropic [number of iteration (int)] [time step (float)] [input img path] [mask path] [output img path]
