A novel LBP based methods for pavement crack detection

Abstract: Two optimized architectures of Context-based Adaptive Binary Arithmetic Coding (CABAC) are presented in the paper. These are: the software version of CABAC (dedicated to IA-32 and DSP platforms) and the hardware version of CABAC (dedicated to FPGA and ASIC platforms). The paper presents analysis of implementations for both versions of CABAC. The optimized software as well as the hardware version of CABAC was tested in terms of codec throughput.

Constrained contour matching in hand posture recognition

Abstract: In this paper constrained contour models are applied for hand posture recognition in single color images In particular, the proposed algorithm utilizes a class of physics-based modelling methods called Deformable Templates [1],[2],[3] After colorbased image segmentation a contour hypothesis is detected and some features are extracted, suitable for comparison with the template’s geometric properties Several metrics for matching contour templates against image data are discussed The described methods are evaluated experimentally and referred to a known hand posture recognition algorithm

Comparing the Reliability of Regular Topologies on a Backbone Network. A Case Study

Abstract: The aim of this paper is to compare the reliability of regular topologies on a backbone network. The study is focused on a large-scale fiberoptic network. Different regular topological solutions as single ring, double ring or 4-Regular grid are applied to the case study, and compared in terms of degree, diameter, average distance, economical cost and availability. Furthermore, other non-quantitative parameters such as expandability, embeddability and algorithmic support are introduced.
