Region-based image retrieval using color and texture features on irregular regions of interest
(Institute of Electrical and Electronics Engineers Inc., 2015)
The Content-based image retrieval (CBIR) systems and their application in different areas of development, are current research topics, however many of this systems are likely to fail due to use global features which cannot ...
Image categorization through optimum path forest and visual words
(2011-12-01)
Different from the first attempts to solve the image categorization problem (often based on global features), recently, several researchers have been tackling this research branch through a new vantage point - using features ...

Compact and discriminative approach for encoding spatial-relationship of visual words
(Association for Computing Machinery - ACMUniversity of SalamancaSalamanca, 2015-04)
The Bag-of-Visual-Words approach has been successfully used for video and image analysis by encoding local features as visual words, and the final representation is a histogram of the visual words detected in the image. ...
Combining global with local texture information for image retrieval applications
(Scopus, 2008)
This paper proposes a new texture descriptor to guide the search and retrieval in image databases. It extracts rich information from global and local primitives of textured images. At a higher level, the global macro-features ...
Classification of rock lithology by laser range 3D and color images
(Elsevier, 2017)
The determination of hardness and approximate mineral composition of rocks and classifying these litholo-gies aids in controlling various processes in the plant, such as reducing the grinding process, which accountsfor ...
A contribution for single and multiple faces recognition using feature-based approaches
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2013-06-28)
Among biometric recognition systems, face biometrics plays an important role in research activities and security applications since face images can be acquired without any knowledge of individuals. Nowadays a huge amount ...
Global, semi-global and local color angular features for unsupervised face recognition
(Curitiba, 2003)
In face recognition applications, dealing with images under different conditions is a challenging task because they can affect dramatically the recognition performance. Among many image features, color is an useful feature ...
Stairway segmentation using Gabor Filter and vanishing point
(08/07/2011)
This paper we are proposing to detect the localization and recognition of an indoor stairway. This is a fundamental step in the implementing of autonomous stair climbing navigation, as well as the implementing of passive ...
