warp_rbf

Arguments:

  • xs0[%],ys0[%],xt0[%],yt0[%],...,xsN[%],ysN[%],xtN[%],ytN[%]

Description:

Warp selected images using RBF-based interpolation.

Each argument (xsk,ysk)-(xtk,ytk) corresponds to the coordinates of a keypoint
respectively on the source and target images. The set of all keypoints define the overall image deformation.

Example of use:

image.jpg +warp_rbf 0,0,0,0,100%,0,100%,0,100%,100%,100%,100%,0,100%,0,100%,50%,50%,70%,50%,25%,25%,25%,75%

Command: image.jpg +warp_rbf 0,0,0,0,100%,0,100%,0,100%,100%,100%,100%,0,100%,0,100%,50%,50%,70%,50%,25%,25%,25%,75%
