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...
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...
This paper briefly presents an efficient and intuitive 3D freeform deformation approach based on iterative affine transformations, a generalized de Casteljau algorithm, whereby th...
This paper describes a new technique for passive ranging which is of special interest in areas such as covert nap-of-the-earth helicopter flight and spacecraft landing. This techn...
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...
Abstract— In this article we present a novel design of a lowpower geometric mapping co-processor that can be used for high-performance graphics system. The processor can carry ou...
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...
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'...
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...
An object seen from different viewpoints results in differently deformed images. Affine-invariant shape classification must classify correctly the object, disregarding its viewpoi...
