5. Automatic VHDL generation for solving rotation and scale-invariant template matching in FPGA. / Geração automática de módulos VHDL para localização de padrões invariante a escala e rotação em FPGA.
Template matching is a classical problem in computer vision. It consists in detecting the presence of a given template in a digital image. This task becomes considerably more complex with the invariance to rotation, scale, translation, brightness and contrast (RSTBC). A novel RSTBC-invariant robust template matching algorithm named Ciratefi was recently prop

10. Aquarius II â Uma plataforma para desenvolvimento de sistemas dinamicamente reconfigurÃveis baseada no sistema operacional uCLinux
The programmable logic devices, FPGAs (Field Programmable Gate Arrays) have been used for a long time as tools for digital circuits prototyping. However, this reality has changed since the computational power of these devices increased and cost decreased. Besides, the FPGAs in use nowadays consume less energy than a conventional CPU to do the same work. Anot

12. Detecção de movimento de objetos em tempo real utilizando dispositivos de lógica programável complexa / Real time detection of moving objects using programmable logic devices
A system that performs movement detection in a sequence of images looks for signs that confirm the occurrence of the movement in the controlled environment. Once the movement of the object is detected it is possible to perform the tracking of the object. Real time object detection and tracking techniques are of great interests to researchers and industries b
