Parametric Estimation of Affine Transformations: An Exact Linear Solution
Abstract We consider the problem of estimating the geometric deformation of an object, with respect to some reference observation on it. Existing solutions, set in the standard coo...

Qualitative Visual Interpretation of 3d Hand Gestures Using Motion Parallax
We present an efficient and geometrically intuitive algorithm to reliably interpret the image velocities of moving objects in 3D. It is well known that in a small neighbourhood th...

A generalized de Casteljau approach to 3D free-form deformation
This paper briefly presents an efficient and intuitive 3D freeform deformation approach based on iterative affine transformations, a generalized de Casteljau algorithm, whereby th...

Matching Patterns of Line Segments by Eigenvector Decomposition
This paper presents an algorithm for matching line segments in two images which are related by an affine transformation. Images are represented as patterns of line segments. Areas...

Projective Transformations for Image Transition Animations
Transformation of image patches is a common requirement for 2D transition animations such as shape interpolation and image morphing. It is usually done by applying affine transfor...

Affine Invariant Dynamic Time Warping and its Application to Online Rotated Handwriting Recognition
Dynamic Time Warping (DTW) has been widely used to align and compare two sequences. DTW can efficiently deal with local warp or deformation between sequences. However, it can'...

Using affine correspondence to estimate 3-D facial pose
We describe a method for tracking a person's face through an image sequence and estimating the 3-D facial pose within each frame. It is based on an affine approximation to th...

New features for affine-invariant shape classification
An object seen from different viewpoints results in differently deformed images. Affine-invariant shape classification must classify correctly the object, disregarding its viewpoi...
