2007, Information SciencesCitation Excerpt :An improvement of about 3 dB was reported in the prediction PSNR of 21 × 21 blocks as compared to the conventional translation-only motion model. Moreover, in [10,21], a motion compensation algorithm based on an eight-parameter perspective model was introduced to describe arbitrary 3D motion of a planar rigid object. Papadopoulos and Clarkson [25] extended Keesman’s affine transform motion model into second-order geometric transformations (GT) that employ 12 parameters capable of describing uneven shearing.
