An iterative approach for estimation of efficiency by weighted distance

Iterative Estimation of Rotation and Translation using the Quaternion

In this paper, we consider some practical issues when using the quaternion to represent rotation in conjunction with gradientor Jacobian-based search algorithms. Iterative estimation techniques often incorporate gradient or Jacobian information to simultaneously solve for the parameters with respect to many non-linear constraints. We derive a simple form for the Jacobian of the rotation matrix ...

Fast Global Motion Estimation using Iterative Least-Square Estimation Technique

Global motion estimation is an important task in a variety of video processing applications, such as coding, segmentation, classificatiodindexing, and mosaicing. The main difficulty in global motion parameter estimation resides in the disturbances due to the independently moving objects. The Iterarive Leaf-Square Estimati’on (USE) technique [l] is commonly used in estimating a fourparameter mod...

Simultaneous Multiple Rotation Averaging Using Lagrangian Duality

Multiple rotation averaging is an important problem in computer vision. The problem is challenging because of the nonlinear constraints required to represent the set of rotations. To our knowledge no one has proposed any globally optimal solution for the case of simultaneous updates of the rotations. In this paper we propose a simple procedure based on Lagrangian duality that can be used to ver...
