Many brain–computer interface (BCI) studies overlook the channel optimization due to its inherent complexity. However, a careful selection increases performance and users’ comfort while reducing cost of system. Evolutionary meta-heuristics, which have demonstrated their usefulness in solving complex problems, not been fully exploited yet this context. The purpose study is two-fold: (1) propose ...

raditionally, communication sage passing) communication system. The among processes in a distributed shared memory model applied to loosely a system is based on the data-passing model. Message-passing systems or systems that support remote procedure calls (RPCs) adhere to this model. The data-passing model logically and conveniently extends the underlying communication mechanism of the system; ...

Computer Vision Algorithms on Reconfigurable Logic Arrays By Nalini K. Ratha Computer vision algorithms are natural candidates for high performance computing due to their inherent parallelism and intense computational demands. For example, a simple 3 3 convolution on a 512 512 gray scale image at 30 frames per second requires 67.5 million multiplications and 60 million additions to be performed...

1 Introduction The remote sensing and computer vision communities share a common goal of extracting useful information from raw imagery. Both communities have exploited several trends that support the increasingly timely, cost effective, accurate, and effective automated extraction of information from raw imagery that include increasingly powerful, affordable, and available computer hardware; i...

The paper presents an introduction to computer topology with applications to image processing and computer graphics. Basic topological notions such as connectivity, frontier, manifolds, surfaces, combinatorial homeomorphism etc. are recalled and adapted for locally finite topological spaces. The paper describes data structures for explicitly representing classical topological spaces in computer...

Acknowledgements There are many people I would like to thank for helping make this thesis possible. I'd like to start out by thanking my mom and dad. Without their support, love and infinite patience I doubt it would be possible for me to be where I am today. I'd also like to thank all of my family (no names for fear of leaving anyone out). They've been great to me throughout the years, always ...
