Reconstruction of HOT curves from image sequences
David Kriegman, B. V. K. Vijaya Kumar, Jean Ponce · 2002
An approach is presented for reconstructing two types of 3-D higher order tangency (HOT) curves from a sequence of images. These curves are useful for object recognition. The reconstruction results for bitangents are encouraging in comparison to those of inflections. They are probably more accurately reconstructed because they are readily located in images, and their common tangent is very accurately estimated from the point locations. This makes bitangents a good feature choice for recognition.>
