Affine alignment of compound objects: A direct approach

Csaba Domokos, Zoltan Kato
2009 2009 16th IEEE International Conference on Image Processing (ICIP)  
A direct approach for parametric estimation of 2D affine deformations between compound shapes is proposed. It provides the result as a least-square solution of a linear system of equations.  ...  The basic idea is to fit Gaussian densities over the objects yielding covariant functions, which preserves the effect of the unknown transformation.  ...  CONCLUSION In this paper we proposed a novel approach to estimate 2D affine transformations between compound shapes.  ...

2009 2009 IEEE 12th International Conference on Computer Vision Workshops, ICCV Workshops  
Calibrating a camera means determining the geometric properties of the imaging process, i.e., the transformation that maps a three-dimensional point, expressed with respect to a reference frame, onto its  ...  Although the camera calibration problem is well understood, no method allowing the robust direct on-line self-calibration for any central omnidirectional camera is known.  ...  Sometimes the field of view band can be aligned vertically, or in any other plane, usually by means of deploying a circularly symmetrical mirror aligned in the required direction.  ...
