Support vector machines for classification of input vectors with different metrics
(ScienceDirect, 2011-05)
In this paper, a generalization of support vector machines is explored where it is considered that input vectors have different ℓp norms for each class. It is proved that the optimization problem for binary classification ...

A similarity measure between videos using alignment, graphical and speech features
(ScienceDirect, 2012)
A novel video similarity measure is proposed by using visual features, alignment distances and speech transcripts. First, video files are represented by a sequence of segments each of which contains colour histograms, ...

A model for the qualitative description of images based on visual and spatial features
(ScienceDirect, 2012)
An approach that provides a qualitative description of any image is presented in this paper. The main visual features (shape and colour) and the main spatial features (fixed orientation, relative orientation and topology) ...

A study on output normalization in multiclass SVMs
(ScienceDirect, 2013-02)
The use of binary support vector machines (SVMs) in multi-classification is addressed in this paper. Margins associated to the bi-classifiers, since they depend on the geometrical disposition of the classes being separated, ...

Measures of Similarity Between Objects Based on Qualitative Shape Descriptions
(Taylor & Francis, 2013-06)
A computational approach for comparing qualitative shape descriptions (QSDs) of objects within digital images is presented. First, the dissimilarity of qualitative features of shape is measured: (i) intuitively using ...

Outdoor exit detection using combined techniques to increase GPS efficiency
(Elsevier, 2012)
The recent boom of GPS (Global Positioning System) as a universal method of location has meant that most people in developed countries have already used this technology sometime in their lives. However, this system suffers ...

Online motion recognition using an accelerometer in a mobile device
(ScienceDirect, 2012-02)
This paper introduces a new method to implement a motion recognition process using a mobile phone fitted with an accelerometer. The data collected from the accelerometer are interpreted by means of astatistical study and ...
