摘要
文章提出了一种基于FPGA从视频图像中检测雪花的实现方案。文中阐述了系统的总体设计方案,软件仿真结果以及硬件结果。通过对不连续的帧图像求平均值的方法得到静态背景图像,存储在SRAM中,外部输入的视频数据与存储的背景图像进行比较得到二值化图像,从而得到视频图像中雪花的检测。
This paper presents a kind of realizations about detecting snow from images based on FPGA. Overall scheme of the system is discussed in the paper. The parper also presents the results of the software simulation and the hardware. Getting the static background image from the video through the calculating the average about the discontinuous frames. The background image is stored in SRAM. After comparing between the data inputting outside and the data from the SRAM, get the binary image.Then the detection of snow from video is obtained.
