A system that allows people to simultaneously modify a common design in a graphically rich environment was developed to identify and examine groupware interface issues unique to t...
In this paper we address the problem of using quaternions in unconstrained nonlinear optimization of 3-D rotations. Quaternions representing rotations have four elements but only ...
Linear techniques are widely used to reduce the dimension of image representation spaces in applications such as image indexing and object recognition. Optimal Component Analysis ...
