Implementation of advanced peripheral bus interface for MV1O MCU

MV10 is an MCU which consists of PWM,ADC,CAN and some other function blocks.It is designed for car body's control.Advanced peripheral bus (APB) is a low speed AMBA bus connecting low-power peripherals.This paper presents an implementation of APB interface for MV10 MCU.After that,MV10 can be integrated into any AMBA system on chips (SoCs) easily.We have built a multi-core system with ABMA to verify this design.In this system ARM9 is a main processor mounted on AHB and MV10 acts as a low-power and low-speed slaver on APB.Before building this system,some operations are encapsulated into a task with dedicated ID.MV10 works as a co-processor with ARM by acquiring task ID from ARM.The result of simulation indicates that MCU can work well as expected.Based on our design,MV10 can be mounted on any AMBA system from now on.     

一种有效的基于运动矢量场的压缩域运动对象分割算法

In this paper an efficient compressed domain moving object segmentation algorithm is proposed, in which the motion vector (MV) field parsed from the compressed video is the only cue used for moving object segmentation. First the MV field is temporally and spatially normalized, and then accumulated by an iterative backward projection to enhance salient motions and alleviate noisy MVs. The accumulated MV field is then segmented into motion-homogenous regions using a modified statistical region growing approach. Finally, moving object regions are extracted in turn based on minimization of the joint prediction error using the estimated motion models of two region sets containing the candidate object region and other remaining regions, respectively. Experimental results on several H.264 compressed video sequences demonstrate good segmentation performance.     

A fast motion estimation algorithm for mobile communications

The limitation of processing power, battery life and memory capacity of portable terminals requires reducing encoding complexity in mobile communications. Motion estimation (ME) is the most computationally intensive module in a typical video codec, which determines not only the encoder's performance but also the reconstructed video quality. In this paper, a fast ME algorithm for H.264/AVC baseline profile coding is proposed based on the analysis of motion vector field and error surface, and the statistical distributions of different type macroblocks (MBs). Simulation results showed that: in comparison with MVFAST, the proposed algorithm can decrease the computational load over 7.2% with no requirement of expanding memory capacity while maintaining the same video quality as MVFAST. Furthermore, its simplicity makes it easy to be implemented on hardware.

新媒体时代欧美MV艺术的个性化发展

MV即音乐录像,是音乐的视觉表现形式,诞生于20世纪80年代的美国。如今MV已发展成为全球性的视觉文化元素之一。技术手段的快速发展,促使音乐电视的艺术表现形式更加趋向个性化。在新媒体环境下,欧美MV艺术的发展一直处于领先地位,无论是从风格趋势还是形式表达亦或视觉心理,都表现出更加具有反模式化创意、无厘头拼贴和超现实主义风格等艺术特征。影像艺术如此频繁地与数字技术联姻,使得MV艺术更像是一种可以超越视听表层而更具主观性的视觉表现,其意义的传达有赖于观众对画面的自我理解。
