Block unshifting high-accuracy motion estimation: A new method adapted to super-resolution enhancement

作者：

Highlights：

•

• An innovative approach to sub-pixel motion estimation.

• Treats blocks in both anchor and target frame equally.

• ”Unshift” estimates an original block from its sub-pixel shifted version.

• Constructed implied block approximates anchor and target blocks through shifts.

• Results show proposed method more accurate than classic motion estimation.
