Two new techniques based on nonparametric estimation of probability densities are introduced which improve on the performance of equivalent robust methods currently employed in computer vision. The first technique draws from the projection pursuit paradigm in statistics, and carries out regression Mestimation with a weak dependence on the accuracy of the scale estimate. The second technique exp...

Bures distance holds a special place among various measures due to its several distinguished features and finds applications in diverse problems quantum information theory. It is related fidelity and, other things, it serves as bona fide measure for quantifying the separability of states. In this work, we calculate exact analytical results mean root square between fixed density matrix random ma...
