摘要

本文主要介绍一种利用TMS 32010数字信号处理器（DSP）和IBM-PC/XT微机构成的微机遥感图像快速处理系统。在此系统上

我们根据微波遥感图像的特点

采用TMS32010宏汇编语言研制出了一个遥感图像快速处理软件库。经过机载微波辐射计图像处理检验

采用TMS 32010语言编程在该系统上的图像处理速度要比采用FORTRAN语言编程在普通微机系统上的图像处理速度提高了100-500倍。此外

本文还提出一种新的平滑滤波算法。该算法滤除高斯白噪声的能力要优于中值滤波

同时还可以保护图像的边缘不被模糊。

Abstract

In this paper

a high-speed processing system to remote images consisting of the TMS32010 digital signal processors and IBM-PC/XT microcomputer is mainly described. In the system

according to feature of remote images

a software package of high-speed remote image processing is developed with TMS32010 macro-assembler. Through practical test of images of airborne image microwave radiometer

the speed of image processing with TMS32010 language in the system is from 100 to 500 times faster than common microcomputer system with FORTRAN language. In addition

a new smooth algorithm is mentioned. It is better than the median filter in filtering out the Gauss white-noise and protecting the edge of images.
