Non-conventional database management systems are used to achieve a better performance when dealing with complex data. One fundamental concept of these systems is object identity (OID), because each object in the database has a unique identifier that is used to access and reference it in relationships to other objects. Two approaches can be used for the(More)
Non-conventional database management systems are used to achieve a better performance when dealing with complex data. One fundamental concept of these systems is object identity (OID). Two techniques can be used for the implementation of OIDs: physical or logical. A logical implementation of OIDs, based on an Indirection Table, is used by NuGeM, a(More)
The main application area in this project, is to deploy image processing and segmentation techniques in computer vision through an omnidirectional vision system to agricultural mobile robots (AMR) used for trajectory navigation problems, as well as localization matters. Thereby, computational methods based on the JSEG algorithm were used to provide the(More)
The increase in the demand for computing resources with scalable infrastructure and easily managed has stimulated the emergence of IaaS - Infrastructure-as-a-Service - providers in public clouds, as well as the creation of open source IaaS solutions for institutions that prefer to implant their own private cloud. Aiming at expanding the cost-benefit, it is(More)
Catadioptric Vision Systems have wide vision field of 360-degree of the environment explored, using combination of lenses and mirrors. It is commonly used in structured indoor environments with static obstacles and when submitted in applications operating in outdoor(and rural) environments, encourage arbitrary and various issues that affect the processing(More)
The development of new technologies that use peer-to-peer networks grows every day, with the object to supply the need of sharing information, resources and services of databases around the world. Among them are the peer-to-peer databases that take advantage of peer-to-peer networks to manage distributed knowledge bases, allowing the sharing of information(More)
This paper presents a methodology for automatic construction of image operators using a linear genetic programming approach, for binary, gray level and color image processing, where the processing solution for a particular application is expressed in terms of the basic morphological operators, dilation and erosion, in conjunction with convolution and(More)
In this project, the main focus is to apply image processing techniques in computer vision through an omnidirectional vision system to agricultural mobile robots (AMR) used for trajectory navigation problems, as well as localization matters. To carry through this task, computational methods based on the JSEG algorithm were used to provide the classification(More)
