For the traditional problems of template drift and the low efficiency of algorithms in video image target tracking applications. A new template tracking algorithms based on active drift correction is proposed. The algorithm incorporates a drift correction term and a target tracking term. By adding a drift correction term into the traditional affine image alignment algorithms and update the template...
In the open hardware graphics accelerator (ORGFX), there are rectangle, line, triangle and curve rasterization modules. This paper is only focused on the improvement of line rasterization speed. Besides modifying the algorithm itself, hardware implementation and resource consumption are put into consideration here. Originally, ORGFX uses the classic Bresenham line algorithm with high precision and...
Usually, the deadbeat control strategy is applied to three-phase voltage source PWM rectifiers. Often, deadbeat control uses a forward predictive algorithm of the reference current to compensate the control delay. Because of the uncertainty of reference variations, single predictive algorithm may cause large current overshoot or phase delay in different reference changes. The paper obtained the relationship...
In RAID system, the disk cache for improving RAID system performance is a very important aspect. Two-level cache displays superior performance in comparison to single cache and is effective in temporal and spatial locality. The proposed cache system in this paper consists in two levels. The first level cache is a set associative cache with small block size whereas the second level cache is a fully...
In this paper, the file system principles and RAID algorithm were studied in Linux, current MD driver and RAID performance were anglicized in detail, achieved a RAID algorithm in the field of multimedia applications, this algorithm enhanced the RAID server to read performance effectively, broke i386 operating system's 4K paging limit, used the new pile of management memory, and through the experimental...
