| 摘 要： | 以Xilinx公司生产的FPGA芯片XC4VSX25及其开发系统为实验平台,针对TVP5150视频解码器输出的ITU-R BT.656格式数据,采用帧内滤波方法,通过VHDL硬件语言设计空间域滤波器,实现视频灰度信号的实时提取,并对每帧视频数据在二维空间内进行滤波与处理,这种方法可用于实时处理要求较高的场合。

| Abstract: | Based on experimental platform of Xilinx Company’s FPGA chip XC4VSX25 and its development system,spatial filter module design is implemented to obtain video signals in real-time gray-scale extraction by use of the TVP5150 video decoder output of ITU-R BT.656 format data,intra-frame filtering method and VHDL hardware design language.Video data of each frame is filtered and processed in two-dimensional space.The method can be used for situation of requiring real-time processing. |
