warp_by_plane — 3D plane_sweep_stereo op

• Data kinds: image2d → image2d

• Call: import plane_sweep; plane_sweep.warp_by_plane(img: 'np.ndarray', H: 'np.ndarray', order: 'int' = 1, cval: 'float' = nan) -> 'np.ndarray' (or ops3d.get("warp_by_plane"))

Usage

Inverse-warp img by the homography H. → out[y,x] = img(H·(x,y,1)) (bilinear).
