In a series of recent papers Singh et al. have explored the idea of Simultaneous Localization and Mapping (SLAM) using range-only measurements. These measurements, obtained from radio or sonar sensors, come at irregular time intervals. In this report we explore the use of interpolation to generate data equally spaced in time, in order to improve the performance of SLAM algorithms. We test this ...
This paper presents a new class AB programmable square-root domain (SRD) filter. The main advantages of the proposed circuits are low power consumption, wide input dynamic range with small standby current and potential for low-voltage operation. Simulation results confirm the validity of the proposed design technique and the high performance of the proposed circuits. Key-Words: Square-root doma...
We show how any BSP tree TP for the endpoints of a set of n disjoint segments in the plane can be used to obtain a BSP tree of size O(n · depth(TP )) for the segments themselves, such that the range-searching efficiency remains almost the same. We apply this technique to obtain a BSP tree of size O(n log n) such that ε-approximate range searching queries with any constant-complexity convex quer...
Wide dynamic range images (WDRIs) are needed for capturing scenes which include drastic lighting changes. This paper presents a method to widen the dynamic range of a camera by using a reflective liquid crystal. The system consists of a camera and a reflective liquid crystal placed in front of the camera. By controlling the attenuation ratio of the liquid crystal, scene radiance of each pixel i...
This paper presents design techniques to evaluate the noise and distortion of continuous time Gm-C filters. Also presents techniques to improve the dynamic range of such filters keeping a relation of integer numbers between the transconductors. Furthermore the comparison of the dynamic range for the same power using different structures is presented.
