13. Aprendizagem por reforço na adaptação a obstáculos em navegação robótica autônoma não-estruturada baseada em imagens / Reinforcement learning for obstable avoidance in image based robotic autonomous non-structured navigation
In the last decades, robotic has become an important role for society, specially in the manufacturing industry. In recent times, applications of mobile robots, from simple toys to planets explorations, has shown how promising will be the use of these tools in a close future. Though, the cost and complexity in developing mobile robots nowadays, which should b

14. Development of an omnidirectional vision system
Omnidirectional vision systems can provide images with a 360° of field of view. For this reason, they can be useful to robotic applications such as navigation, teleoperation and visual servoing. An effective way to construct this type of vision system is by combining lenses and mirrors together resulting on a system that does not require the movement of the

16. Sistema de visão robótica para identificação e localização de objetos sob manipulação por robôs industriais em células de manufatura.
There are several techniques for applying robotic vision for identification and localization of industrial objects. These objects are typically found in manufacturing cells. The purpose is to catch and transport the pieces for automatically grouping. Robotic vision for industrial objects is an important and still difficult task, especially feature extraction

17. EXPLORATION AND VISUAL MAPPING ALGORITHMS DEVELOPMENT FOR LOW COST MOBILE ROBOTS / DESENVOLVIMENTO DE ALGORITMOS DE EXPLORAÇÃO E MAPEAMENTO VISUAL PARA ROBÔS MÓVEIS DE BAIXO CUSTO
As the autonomy of personal service robotic systems increases so has their need to interact with their environment. The most basic interaction a robotic agent may have with its environment is to sense and navigate through it. For many applications it is not usually practical to provide robots in advance with valid geometric models of their environment. The r

18. POSICIONAMENTO E CALIBRAÇÃO DE UM MANIPULADOR ROBÓTICO SUBMARINO COM USO DE VISÃO COMPUTACIONAL / POSITIONING AND CALIBRATION OF A UNDERWATER ROBOTIC MANIPULATOR WITH USE OF COMPUTACIONAL VISION
Muitos dos robôs industriais utilizados atualmente seguem uma programação baseada em rastreamento de trajetórias. O robô é guiado por um operador humano para localizações fixas onde ele atuará. Esses movimentos são, então, gravados na linguagem de programação residente no controlador do robô, de forma que este seja capaz de repetir as tarefas.

20. Performance evaluation of 3D computer vision techniques
This work presents the implementation and comparison of three different techniques of three-dimensional computer vision as follows: • Stereo vision - correlation between two 2D images • Sensorial fusion - use of different sensors: camera 2D + ultrasound sensor (1D); • Structured light The computer vision techniques herein presented took into considerat

21. Segmentação de imagens por classificação de cores: uma abordagem neural. / Image segmentation by color classification: a neural approach.
The present work approaches the segmentation of colored images through the process of color classification, i.e., the segmentation of images based on the color attribute of pixels. We look for a color classification as close as possible of human classification. In other words, we look for a robust classification with respect to the variation of illumination

22. Tecnologia para o reconhecimento do formato de objetos tri-dimensionais. / Three dimensional shape recognition technology.
We present in this work a new method for three dimensional Shape Recognition. Traditional Computer Vision systems use bi-dimensional TV camera images. In most of the industrial Robotic applications, the excess of detail obtained by the TV camera is needless. Traditional classification algorithms spend a lot of time to process the excess of information. For t

23. Automated high resolution optical mapping using arrayed, fluid-fixed DNA molecules
New mapping approaches construct ordered restriction maps from fluorescence microscope images of individual, endonuclease-digested DNA molecules. In optical mapping, molecules are elongated and fixed onto derivatized glass surfaces, preserving biochemical accessibility and fragment order after enzymatic digestion. Measurements of relative fluorescence intens
