New Global Motion Algorithm

Technology Description

UC San Diego inventors have devised a global motion estimation technique for affine motion vectors with the following benefits:

• Requires less computational overhead.
• Relies on the easy-to-compute FFT.
• Highly parallelizable.
• Robust to illumination changes and occlusion.
• Not significantly effected by calculations involving large movements.
• Does not require a starting guess.
• Scalable between accuracy computational power.
• MPEG4 object layer coding.

State Of Development

Software has been implemented using this algorithm (see SD2010-813) and is available for licensing with the patent rights. Also see issued patent 7,349,583.
