Feature Extraction for Classification: a Survey I. Linear Methods
The growing volume of information available as input in pattern classification systems has imposed the use of pre-processing techniques which have the purpose of reducing the feature space dimensions. The references in this domain are very large and only an exhaustive approach can be made. This article presents the most used linear methods, comparing their advantages and disadvantages, and show...
متن کاملFeature Extraction Methods & Applications
There are numerous methods to classification of feature types. Imagine provides classification models in addition to texture features and convolution methods that assist in detecting various feature types. Using ESRI's ArcView and ArcGIS Feature Analyst extension, the process of feature extraction is readily accessible and user-friendly to the analyst. But, in general, road detection, specifica...
متن کاملFeature Selection and Non-linear Feature Extraction
Feature extraction and feature selection are two important tasks in pattern recognition. Classiication algorithms like k-nearest neighbors, which are based on the assumption that patterns in the same class are close to each other and those in diierent classes are far apart (locality property), rely heavily on the quality of the features extracted from the input data. In this work, an objective ...
متن کاملSupervised Methods for Feature Extraction
It is present in this paper the feature extraction for pattern recognition tasks. It is proposed two approaches. In the first, it is used weights to scale the coordinates of the features vector in order to increase the precision of statistical classifiers. Genetic algorithm is intended to do weight adjustments. In the second approach the Battacharyya metric is suggested. Theses approaches make ...
متن کاملLinear Feature Extraction Based On Grouping Factors
Human vision has marvelous ability in extracting linear features from images, such as roads, rivers and so on. In this paper we present a new method to simulate this ability. Our method is based on some general grouping factors arising at two levels. At the first level, grouping factors are identified as direct bar-bar interaction and orientation interaction. Bar-bar interaction is shortranged ...
