摘要
针对自动提取方法及半自动提取方法的缺点,提出了一种在Blackfin-533 DSP(Digital Signal Processor)芯片上实现的视频对象提取方法。该方法是利用图像多帧差累积的高阶统计量来提取出视频对象,设计了DSP实现系统并对算法进行了测试。测试结果表明,该算法可以满足当前多种视频图像处理实时应用需求,具有良好的应用前景。
With the development of computer and multimedia technology, the study of extracting of video object from video sequence is becoming a hot issue in the image processing. This paper presents a video object extraction method based on chip of Blackfin-533 DSP （Digital Signal Processor）. The high order statistics of multi-frame difference accumulation are used in the video object extraction. The algorithm makes full use of the DSP （Digital Signal Processor）high-performance in the data processing. The experiments have testified that the algorithm can meet many application needs in the field of image processing and has good application prospects.
