TUNNEL MODELING USING MOBILE MAPPING LIDAR POINTS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021
In this paper, a method to model a tunnel using lidar points is presented. The data used was collected using Leica Pegasus Two Ultimate with a Z+F 9012 Profiler mounted on a mobile platform. The tunnel was approximately 151 m long.

Dynamic and Approximate Pattern Matching in 2D [PDF]

open access: yes, 2016
We consider dynamic and online variants of 2D pattern matching between an \(m \times m\) pattern and an \(n \times n\) text. All the algorithms we give are randomised and give correct outputs with at least constant probability.

Weighted approximate parameterized string matching

open access: yesAKCE International Journal of Graphs and Combinatorics, 2017
We consider the problem of finding a bijection to match a pattern in a text where both the pattern and the text are strings from distinct alphabets.

State Complexity of Neighbourhoods and Approximate Pattern Matching [PDF]

open access: yesInternational Journal of Foundations of Computer Science, 2015
The neighbourhood of a language [Formula: see text] with respect to an additive distance consists of all strings that have distance at most the given radius from some string of [Formula: see text]. We show that the worst case deterministic state complexity of a radius [Formula: see text] neighbourhood of a language recognized by an [Formula: see text ...

Revisiting Volgenant-Jonker for Approximating Graph Edit Distance [PDF]

open access: yes, 2015
Although it is agreed that the Volgenant-Jonker (VJ) algorithm provides a fast way to approximate graph edit distance (GED), until now nobody has reported how the VJ algorithm can be tuned for this task.

Dog Identification Method Based on Muzzle Pattern Image

open access: yesApplied Sciences, 2020
Currently, invasive and external radio frequency identification (RFID) devices and pet tags are widely used for dog identification. However, social problems such as abandoning and losing dogs are constantly increasing. A more effective alternative to the

Field pattern of the vertical dipole antenna above a Lossy half-space [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2005
The field pattern of the vertical dipole antenna (VDA) placed above a homogenous and isotropic medium is determined in this paper. The unknown current distribution (UCD) on the antenna is evaluated by solving the system of integral equations of Hallen’s ...

On String Matching with Mismatches

open access: yesAlgorithms, 2015
In this paper, we consider several variants of the pattern matching with mismatches problem. In particular, given a text \(T=t_1 t_2\cdots t_n\) and a pattern \(P=p_1p_2\cdots p_m\), we investigate the following problems: (1) pattern matching with ...

Creating Image Mosaics using Statistical Methods for Images Alignment [PDF]

open access: yesمجلة التربية والعلم, 2011
Image mosaics is a collection of small images arranged in a way that when they are seen from a distance they seen as larger image. It occupies a wide field in computer vision and image processing area. This field is performed in four stages. These stages
