Accurate vehicle location is essential for various applications in the field of intelligent transportation systems (ITS). Existing vehicle location systems rely on multiple positioning sensors and powerful computing devices to execute complex map matching algorithms. There exists a strong need for exploring a solution for vehicle location that relies on a(More)
A new segmentation algorithm for lumen region detection and boundary extraction from gastro-intestinal (GI) images is presented. The proposed algorithm consists of two steps. First, a preliminary region of interest (ROI) representing the GI lumen is segmented by an adaptive progressive thresholding (APT) technique. Then, an adaptive filter, the Iris filter,(More)
Residue number system is popular in high performance arithmetic applications like digital signal processing because of its carry free nature, modularity and error correcting properties. But these opportunities are eclipsed by the high area and time requirements for reverse conversion. In this regard, we present two new techniques for residue-toweighted(More)
Real-time traffic queue detection can directly aid in dynamic traffic light control at road junctions. In this paper, we propose an efficient technique to detect vehicle queue lengths at traffic junctions based on progressive block based image processing. We also propose a two-step approach for vehicle detection that relies on edges and dark features in the(More)

As embedded systems evolve, there is greater dependency on the real-time operating system (RTOS) to abstract the complex hardware. In return for the services provided, the RTOS consumes CPU cycles, thereby imposing a processing overhead on the CPU. In this paper, we review some of the techniques that have been proposed in literature for reducing the CPU(More)
Even though it has been shown that residue number systems (RNS) provide very fast and reliable arithmetic due to its inherent parallel processing and error correction capabilities, its use is severely limited to a few applications due to the complexities involved in its conversion circuitry. Hence the design of efficient converters is still considered an(More)
Reconfigurable processors provide an attractive means to meet the constraints of embedded devices due to their instruction set extension capabilities. We propose a novel technique to estimate the area utilization of LUT (Look-Up Table) based FPGAs (Field Programmable Gate Arrays) for custom instruction realizations. The technique contributes to rapid design(More)
