实时数字电视跟踪系统中值滤波器设计

A Median Filter Design of the Real-Time Video Tracking System

本文提出一种3×3中值滤波算法,利用门阵列GAL器件和快速存贮RAM器件完成6 bits灰度图象中值滤波,提高目标图像的信噪比。并给出理论分析和实验结果。经外场实验取得满意的结果。

A 3 × 3 median filter algorithm is presented in this paper. The 6 bits gray level image median filtering in real-time is implemented by using generic array logic (GAL) devices and fast random access memory (RAM) devices. The signal to noise ratio (SNR) of the target image is improved. The theoretic analysis and simulation results are given. Satisfactory results also have been achieved in battlefield experiment.
