General 2-D Spatial Transformations in MATLAB

MATLAB has changed the protocol for 2-D Spatial Transformations. The original protocol used cp2tform and imtransform. The new protocol uses fitgeotrans and imwarp.

Example 1

MATLAB code:

• planar1.m (original protocol)
• planar2.m (new protocol)
• tform3.m target board, new protocol (download tform3.zip)

The code demonstrates a 3D projective transformation to rectify an oblique view of a planar object. (Download planar.zip)
