“…The HT has rarely been used in robotic systems operating in real time and, when used, it generally needs specific hardware due to its computational complexity. In Robot Soccer, the HT is only used to locate the ball -but not the robots -as described in (Gönner et al, 2005) and (Jonker et al, 2000).…”

“…These models are robust under changing illumination, since they remain invariant over a wide dynamic range when the spectral energy of colored light changes by a constant multiplicative factor [8]. Some papers presenting vision systems with these color models include, for example, [2,4] on HSI, [1,7] on YUV, and [10,12,15] on RGB.…”

This paper presents a web-cam based vision system for performing image processing in real time. It was implemented as part of an AI and Robotics educational platform designed to study collaborative moving robots in a dynamic environment. A color based image segmentation algorithm was developed with careful attention to algorithm efficiency, due to hardware limitations for the maximum frame rate. This led to a simple and cost-effective vision system that is able to detect and identify several mobile robots through successive frames.

SIMD (single instruction multiple data)-type processors have been found very efficient in image processing applications, because their repetitive structure is able to exploit the huge amount of data-level parallelism in pixel-type operations, operating at a relatively low energy consumption rate. However, current SIMD architectures lack support for dynamic communication between processing elements, which is needed to efficiently map a set of non-linear algorithms. An architecture for dynamic communication support has been proposed, but this architecture needs large amounts of buffering to function properly. In this paper, three architectures supporting dynamic communication without the need of large amounts of buffering are presented, requiring 98% less buffer space. Cycle-true communication architecture simulators have been developed to accurately predict the performance of the different architectures. Simulations with several test algorithms have shown a performance improvement of up to 5x compared to a locally connected SIMDprocessor. Also, detailed area models have been developed, estimating the three proposed architectures to have an area overhead of 30-70% compared to a locally connected SIMD architecture (like the IMAP). When memory is taken into account as well, the overhead is estimated to be 13-28%.
