A recursive approach to space resection using straight lines
An approach using straight lines as features to solve the photogrammetric space resection problem is presented. An explicit mathematical model relating straight lines, in both object and image space, is used. Based on this ...
Estimating the queue length at street intersections by using a movement feature space approach
(Institution of Engineering and Technology, 2014-07)
This study aims to estimate the traffic load at street intersections obtaining the circulating vehicle number through image processing and pattern recognition. The algorithm detects moving objects in a street view by using ...
Improving image classification through descriptor combination
The efficiency in image classification tasks can be improved using combined information provided by several sources, such as shape, color, and texture visual properties. Although many works proposed to combine different ...
State of the Art of Fingerprint Indexing Algorithms
(Revista Computación y Sistemas; Vol. 15 No.1, 2011-09-10)
Abstract. Due to the large size that fingerprint databases generally have, the reduction of the search space is indispensable. In the resolution of this problem, indexing algorithms have a fundamental role. In ...

Pedestrian tracking using probability fields and a movement feature spaceSeguimiento de peatones utilizando campos probabilísticos y un espacio de descriptores dinámicos
(Universidad Nacional de Colombia, 2017-01)
Recuperar información de secuencias de video, como la dinámica de peatones u otros objetos en movimiento en la escena, representa una herramienta indispensable para interpretar que está ocurriendo en la escena. Este artículo ...
Partially obscured human detection based on component detectors using multiple feature descriptors
This paper presents a human detection system based on component detector using multiple feature descriptors. The contribution presents two issues for dealing with the problem of partially obscured human. First, it presents ...
Three-Dimensional Semiautomatic Road Extraction From a High-Resolution Aerial Image by Dynamic-Programming Optimization in the Object Space
(Institute of Electrical and Electronics Engineers (IEEE), 2010-10-01)
This letter proposes a method for 3-D semiautomatic road extraction from a single image by dynamic programming (DP), which requires a form of relief representation such as digital terrain model. Unlike traditional DP ...
