Digital image stabilization using similarity transformation over constrained Differential-Radon warping vectors

作者：

Highlights：

• Differential-Radon by incorporating projection shape produces improved correlation.

• Resolution of 0.1 degree provides better inter-frame rotation estimation accuracy.

• Constrained warping of angular slice results improved processing time efficiency.

• Interest vector selection efficiently eliminates curve miswarping singularities.

• Least square solution on interest vector gives extended range of motion parameters.
