摘要
选择TI TMS320DM642 DSP作为实现平台,对其视频驱动的编程开发接口进行了分析.然后,对于AEI算法进行了两方面的修正与改进:采用"逐帧编码"技术,将适合于静态图片的算法应用到了动态视频上;采用"逐通道编码"技术,将适合于灰度图像的算法应用到了彩色图像上.以此为基础,完成了AEI算法的DSP移植.
This paper chooses TI TMS320DM642 DSP as the implementation platform and analysis its video driver developing interface. Then, this paper modifies the Absolute Error Inequality (AEI) algorithm from two aspects: Using the "Frame-By-Frame coding", applies the algorithm of static image on the dynamic video. Using the "Channel-By-Channel coding", applies the algorithm of gray image on the color image. Based on the two improved methods, we transplant the Absolute Error Inequality (AEI) algorithm of VQ on the DSP platform.
