This new method is now widely used in indusrial vision and image analysis and now included in the Image Understanding Environment. Ellipse-specific fitting methods were only iterative and slow before this work, which has also shown considerable stability properties. This new method is inspired by previous works by Scott and Longuet-Higgins. It allows to match features across a pair of stereo images with unparalleled algorithmic simplicity and neatness.
Results are comparable to complex relaxation methods.
Motion re-estimation from raw MPEG motion vectors with application to Image Mosaicing MPEG streams contain information about the camera and object motion encoded in their motion vectors. Applications of the method are in areas such as image compression, 3D avatar generation and object rendering. The IBR method consists in linearly morphing and alpha-blending corresponding patches of two or more images which gives a compeling sensation of tridimensionality. Given the demanding graphics performance needed it was not clear what SW technology to use. Unfortunately when it comes down to fitting them to data, their strong non-linearities is a big hurdle.
