EM Training of Hidden Markov Models for Shape Recognition Using Cyclic Strings
(Springer Berlin Heidelberg, 2013)
Shape descriptions and the corresponding matching techniques must be robust to noise and invariant to transformations for their use in recognition tasks. Most transformations are relatively easy to handle when contours are ...
Parallel Interconnection of Broadcast Systems with Multiple FIFO Channels
(Springer Berlin Heidelberg, 2009)
This paper proposes new protocols for the interconnection of FIFO- and causal-ordered broadcast systems, thus increasing their scalability. They use several interconnection links between systems, which avoids bottleneck ...
Multi-spectral Texture Characterisation for Remote Sensing Image Segmentation
(Springer Berlin Heidelberg, 2009)
A multi-spectral texture characterisation model is proposed, the Multi-spectral Local Differences Texem – MLDT, as an affordable approach to be used in multi-spectral images that may contain large number of bands. The MLDT ...
Scale Analysis of Several Filter Banks for Color Texture Classification
(Springer Berlin Heidelberg, 2009)
We present a study of the contribution of the different scales used by several feature extraction methods based on filter banks for color texture classification. Filter banks used for textural characterization purposes are ...
Textural Features for Hyperspectral Pixel Classification
(Springer Berlin Heidelberg, 2009)
Hyperspectral remote sensing provides data in large amounts from a wide range of wavelengths in the spectrum and the possibility of distinguish subtle differences in the image. For this reason, the process of band selection ...
Gait Recognition by Ranking
(Springer Berlin Heidelberg, 2012)
The advantage of gait over other biometrics such as face or fingerprint is that it can operate from a distance and without subject cooperation. However, this also makes gait subject to changes in various covariate conditions ...
Assessment of Financial Risk Prediction Models with Multi-criteria Decision Making Methods
(Springer Berlin Heidelberg, 2012)
A wide range of classification models have been explored for financial risk prediction, but conclusions on which technique behaves better may vary when different performance evaluation measures are employed. Accordingly, ...
Continuous Level of Detail for Large Scale Rendering of 3D Animated Polygonal Models
(Springer Berlin Heidelberg, 2012)
Current simulation applications are mainly focused on the efficient management of scenarios with static objects. However, managing dynamic objects, such as animated characters, is very different and requires more specific ...
Gender Classification from Pose-Based GEIs
(Springer Berlin Heidelberg, 2012)
This paper introduces a new approach for gait-based gender classification in which some key biomechanical poses of a gait pattern are represented by partial Gait Energy Images (GEIs). These pose-based GEIs can more accurately ...
Relief Patterned-Tile Classification for Automatic Tessella Assembly
(Springer Berlin Heidelberg, 2010)
This paper presents the detection and classification part of an industrial machine for automated assembly of decorative tessellae over patterned tiles that have significant reliefs. The machine consists of two vision systems ...
