Root Cause

Affine transformation matrix has wrong size.

generic

Workarounds

  1. 92% success Ensure affine matrix is 2x3 and perspective matrix is 3x3
  2. 90% success Use cv2.getAffineTransform() or getRotationMatrix2D() to create correct matrix

Dead Ends

Common approaches that don't work:

  1. Pad matrix to 3x3 78% fail

    Wrong transformation type

  2. Use identity matrix as fallback 68% fail

    No transformation applied
