Toboggan-Based Intelligent Scissors with a Four-Parameter Edge Model

Intelligent Scissors is an interactive image segmentation tool that allows a user to select piece-wise globally optimal contour segments that correspond to a desired object boundary. We present a new and faster method of computing the optimal path by over-segmenting the image using toboggan-ing and then imposing a weighted planar graph on top of the resulting region boundaries. The resulting re...

Anti-Slide

The anti-slide packing is a packing of a number of three dimensional pieces of same size into a larger box such that none of them can slide in any direction. In this paper, we consider the problem of how to find a sparsest anti-slide packing. We give an IP formulation of this problem, and obtain the solutions for some small cases by using an IP solver. In addition, we give the upper and lower b...

Slide Attacks

It is a general belief among the designers of block-ciphers that even a relatively weak cipher may become very strong if its number of rounds is made very large. In this paper we describe a new generic known(or sometimes chosen-) plaintext attack on product ciphers, which we call the slide attack and which in many cases is independent of the number of rounds of a cipher. We illustrate the power...

A Fast Toboggan-based Method for Automatic Detection and Segmentation of Pulmonary Embolism in CT Angiography

Pulmonary embolism (PE), a potentially life-threatening condition, is a result of underlying venous thromboembolic disease. An early and accurate diagnosis is the key to survival. Computed tomography angiography (CTA) has merged as an accurate diagnostic tool for PE. However, there are hundreds of CT slices in each CTA study. Manual reading is laborious, time consuming and complicated by variou...
