How to Put Probabilities on Homographies
October 2005 (vol. 27 no. 10)
pp. 1666-1670
We present a family of "normal” distributions over a matrix group together with a simple method for estimating its parameters. In particular, the mean of a set of elements can be calculated. The approach is applied to planar projective homographies, showing that using priors defined in this way improves object recognition.
