We design several algorithms representing evaluation processes of different complexity, ranging from basic environments based on a predetermined number features to complex structures involving alternatives defined through decision trees whose nodes is determined by the cardinality respective power sets. The sequential structure these builds information retrieval behavior users in online search ...

The increasing prevalence of automated image acquisition systems is enabling new types of microscopy experiments that generate large image datasets. However, there is a perceived lack of robust image analysis systems required to process these diverse datasets. Most automated image analysis systems are tailored for specific types of microscopy, contrast methods, probes, and even cell types. This...

This paper describes the pattern recognition techniques used to develop a robotic interface utilizing neural signals recorded from the primary motor cortex area of the brain. The ultimate objective of this research is to provide severely disabled individuals with a natural method of controlling prosthetic devices. The short term goal of this project is to develop a natural neural signal interfa...

Information is of strategic importance for business and governmental agencies, but also for individual citizens. The use of automatic methods for selection and dissemination of information would enable media monitoring companies to cover a much larger variety of media sources by working more cost efficiently and providing 24 hours coverage and availability. This thesis investigates how professi...

In the present work a model is proposed which is useful for text summarization of the given document by using pattern recognition techniques for improving the retrieval performance of the relevant information. The design and implementation of the proposed systems is concerned with methods for summarizing of the retrieving information from a collection of documents or corpuses. The quality of a ...

Keywords: Biometrics Signature Accelerometer Hidden Markov models Bayes Dynamic time warping As a result of advances in mobile technology, new services which benefit from the ubiquity of these devices are appearing. Some of these services require the identification of the subject since they may access private user information. In this paper, we propose to identify each user by drawing his/her h...

Face recognition has a wide variety of applications such as in identity authentication, access control and surveillance. There has been a lot of research on face recognition over the past few years. They have mainly dealt with different aspects of face recognition. Algorithms have been proposed to recognize faces beyond variations in viewpoint, illumination, pose and expression. This has led to...
