| 摘 要： | 由于FPGA同时具有硬件的快速和软件的灵活两方面的优点,这一平台在图像和视频处理方面的应用日益广泛。然而就目前来说,FPGA主要用于真实感图像或视频的处理,而把FPGA应用于非真实感绘制的研究还是一片空白,因此提出了一种基于FPGA把输入图像处理为铅笔画输出或把输入实时视频处理为铅笔画视频输出的方法。在此方法的探索中,先对铅笔画生成算法作并行性分析,得到适用于FPGA的算法,再在此基础上应用硬件特有的流水线乘法技术进行优化以提高硬件系统的处理速度。 |
| 关 键 词： | 计算机应用 铅笔画 流水线技术 非真实感绘制 |

| Abstract: | Since FPGA has fast speed for hardware and flexibility for software,it has been broadly used in the aspects of the image and video processing.Recently,the FPGA is mainly used in the realistic image or video processing,but it is still a blank to make use of it in the Non-photorealistic rendering research.An effective method is proposed based on the FPGA to output a Pencil Drawing image or video by inputting a realistic image or video.In the research of this method,firstly the parallel characteristic of the automatic pencil drawing simulation algorithm is analyzed.Then the pipelining multiply technology is proposed which is adapted to the hardware for improving the speed. |
| Keywords: | computer application pencil drawing pipeline non-photorealistic rendering |
