摘要
设计了可用于HDTV的多媒体图像后处理系统,并分析了各部分的设计原理以及算法的选择和实现。系统主要包括图像后处理的降噪、去隔行、缩放、锐化增强等部分,对图像劣化现象有很好的重建效果。该系统是可集成在现代数字电视芯片上的SoC系统,经过后处理能够得到高品质的视频图像。
A multimedia image post-processing system based on the praetieal application of digital video is introduced, which can be used in HDTV. And the design principle, the choice and realization of the algorithm is analysed. This system includes the modules of noise reduction, deinterlaeing, sealing, sharpness-enhancement, These modules can reconstruct good images for the usual low-quality images. In one word, this post-processing system can be integrated in the modem digital TV chip SoC to get the high-quality video image after processing.
