一种便于硬件实现的消锯齿的视频处理方法

A Method of Video Processing that is Used to Eliminate Sawtooth and Suited forHardware Implementation

文章是针对在隔行到逐行转换过程中产生的运动虚像和锯齿现象,先提出常用的消运动虚像和锯齿的方法,如基于边缘检测的3×3窗口滤波方法、基于运动检测的滤波方法,接着提出一种便于硬件实现的四方向中值滤波取最大值法,该方法除了硬件实现简单、消锯齿效果好,而且具有降噪和保持图像细节的功能。

This chapter aims at the phenomena of motion fake image and sawtooth when converting the interlaced signal to the progressive signal. Firstly we introduce usual methods to eliminate the fake image and sawtooth, such as 3x3 window's filter based on edge detection, the filter based on motion detection, and secondly we present one maximum value filter method based four directions median filter which suited for hardware implementation. It is not only simple to hardware implementation and has a better effect, but also can reduce the noise and hold image detail.
