inpaint_pde

Arguments:

  • [mask],_nb_scales[%],_diffusion_type={ 0:Isotropic | 1:Delaunay-guided | 2:Edge-guided | 3:Mask-guided },_diffusion_iter>=0

Description:

Inpaint selected images by specified mask using a multiscale transport-diffusion algorithm.

Argument nb_scales sets the number of scales used in the multi-scale resolution scheme.
When the % qualifier is used for nb_scales, the number of used scales is relative to nb_scales_max = ceil(log2(max(w,h,d))).
When nb_scales<0, it determines the minimum image size encountered at the lowest scale.
If diffusion_type==3, non-zero values of the mask (e.g. a distance function) are used
to guide the diffusion process.

Default values:

nb_scales=-9, diffusion_type=1 and diffusion_iter=20.

Example of use:
