When a very fast dynamic event is recorded with a low-framerate camera, the resulting video suffers from severe motion blur (due to exposure time) and motion aliasing (due to low sampling rate in time). True Temporal ...

The directed graph reachability problem takes as input an n-vertex directed graph G=(V,E), and two distinguished vertices v 0, and vertex v *. The problem is to determine whether there exists a path from v 0 to v * in...

We consider the problem of reconstructing the shape of an object from multiple images related by translations, when only small portions of the object can be observed in each image. Lindenbaum and Bruckstein (1988) hav...

This paper presents a simulation tool to help the network designer to identify the optimum network design parameters for a heterogeneous network environment. The tool consists of two parts: simulation modules and a user interface. The simulation modules are created using enhancements of an asynchronous, event-driven C-function library to enable the simulation of heterogeneous scenarios. In the future, this module will be distributed to speed-up the simulation runtime. The user interface helps the user to create the design of the network to be simulated. By this modular concept of distributed simulation modules and user interface the optimum network can be found out without much knowledge of the underlying simulation details.
We investigate the asymptotic behavior, the oscillatory character, and the periodic nature of solutions of the difference equation xn+1 = max{xn, A}/xnxn-1, n = 0, 1, . . . where A is a real parameter and the initial ...

A scheme for recognizing 3D objects from single 2D images is introduced. The scheme proceeds in two stages. In the categorization stage, the image is matched against prototype objects, and in the identification stage, the observed object is matched against the individual models of its class, where classes are expected to contain objects with relatively similar shapes. The advantage of categorizing the object before it is identified is twofold. First, the image is compared to a smaller number of models, since only models that belong to the object's class need to be considered. Second, the cost of comparing the image to each model in a class is very low, because correspondence is computed once for the whole class. The correspondence and object pose computed in the categorization stage to align the prototype with the image are reused in the identification stage to align the individual models with the image. As a result, identification is reduced to a series of simple template comparisons.< >
The problem of finding a piecewise straight-line path, with a constant number of line segments, in a two-dimensional domain is studied in the Turing machine-based computational model and in the discrete complexity the...

This paper presents a new document segmentation algorithm, called context-adapted wavelet-domain hidden Markov tree (CAHMT) model, which extends a recently emerged wavelet-domain hidden Markov tree (HMT) model. The proposed CAHMT can achieve more accurate quality with low computation complexity in document segmentation. In addition to further improving the segmenting performance, we combine differential operator and the lowest frequency subband with CAHMT and produce much better visually segmentation quality than the HMT does.

The study of the shapes of sedimentary particles was presented. The shape of the particle was described by using the roundness as the measurement factor. The analysis study utilized a Fourier transform method to obtain coordinates on the edge of the profile of the fragment being measured. The proposed method described the difference between the low pass filtered radii and original radii as the measure of roundness.
