The weak limit of the normalized number of comparisons needed by the Quicksort algorithm to sort n randomly permuted items is known to be determined implicitly by a distributional fixed-point equation. We give an algorithm for perfect random variate generation from this distribution.

In this paper, we give a new vanishing point detection algorithm, called the normalized unit sphere. By normalizing homogeneous coordinates in the original image space, we transform image points onto a normalized unit sphere. Further, we transform straight lines in image space into circles on normalized unit sphere. As a result, the vanishing point detection is implemented by searching the inte...

A spoof detection algorithm supports the speaker verification system to examine false claims by an imposter through careful analysis of input test speech. The scores are employed categorize genuine and spoofed samples effectively. Under mismatch conditions, acceptance ratio increases can be reduced appropriate score normalization techniques. In this article, we using normalized Discounted Cumul...
