The package can be used to denoise image by block-B-spline(/demo/BSplineSurface).
when get a noisy image:
Firstly, search jump points,and interpolate between the points:
Then, depend on the jump points, segment the image to make each block a continuous image:
Finally, The B-spline is used to fit the surface in each block:
The following image is the original image:
The R package also can be use to calculate the value of B-spline basis，and provide 2D(sin(x) and circular) and 3D(two dimensional density surface and sphere) examples in the demo .
