And Performance

This paper presents an efficient hardware design using the new Motion Estimation (ME) algorithms named: Multi-point Diamond Search (MPDS) and Dynamic Multi-Point Diamond Search (DMPDS). These algorithms are more efficient to avoid from local minima falls than traditional fast algorithms.This fact contributes to increase the quality of the motion vectors, especially in High Definition (HD) videos, were the number of local minima are considerable higher. Two versions of MPDS algorithm were proposed. The first one, focused on high performance, is capable to process videos QFHD at 30 frames per second when synthesized to Altera Stratix 4 and 90nm TSCM, with only 18mW. The second version is focused on quality enhancement and is capable to process HD 1080p videos in real time. The DMPDS architecture has been developed focusing on high performance and was synthesized to Altera stratix 4. This architecture is capable to process videos QFHD at 34 frames per second. In comparison to related works, our solutions obtained the highest processing rates, and a good trade-off among power consumption, area, memory bits and performance.

Tomography is a non-invasive, non-intrusive imaging technique allowing the visualization of phase dynamics in industrial and biological processes. This article reviews progress in Electrical Capacitance Volume Tomography (ECVT). ECVT is a direct 3D visualizing technique, unlike three-dimensional imaging, which is based on stacking 2D images to obtain an interpolated 3D image. ECVT has recently matured for real time, non-invasive 3-D monitoring of processes involving materials with strong contrast in dielectric permittivity. In this article, ECVT sensor design, optimization and performance of various sensors seen in literature are summarized. Qualitative Analysis of ECVT image reconstruction techniques has also been presented.
