基于运动图像细节特征的方向滤波器设计

Design of Direction Filters Based on the Features of Moving Image

为了满足运动图像在嵌入式等系统中的应用,针对运动图像细节特征提出具体的解决方法。首先利用高斯低通滤波器有效滤除了分布噪声,然后分析并提取运动目标的方向,最后,通过实验确定了水平滤波器,提出了基于相位编组法对水平滤波器进行旋转的方法,进而确定方向滤波器。另外,给出了滤波器设计的应用平台。

In order to meet the application of moving image in embedded system, a specific solution based on details feature of moving image was presented. The filter of Gauss was used to filter the distribution noisy efficiently, the direction of moving object was analyzed and abstracted, and the horizontal filter was determined through the method of experimentation and how to rotate the horizontal filter based on the technique of marshalling phase was presented. The marshalling phase can determine the direction of the filter. An applied flat based on the design of these filters was presented.
