NEW IDEAS IN A QUANTITATIVE APPROACH TO IMAGE PROCESSING

The authors present a statistical approach for multi-band image processing based on “synthesizing” processing methods, i.e., methods which transform N original band-specific images into a smaller number of (synthetic) image products. Such techniques are increasingly replacing “one-dimensional” methods (one-to-one correspondence between number of original and processed images) because of the normally greater informational content and enhanced feature discrimination capability afforded by composite image products. The ultimate objective is development of a complex of image processing strategies balancing user demands for information quantity, image diversity, and efficient use of computer time.

DIGITAL IMAGE PROCESSING IN THE COMPILATION OF LUNAR PHOTOMAPS

A method of compiling lunar thematic photomaps is described, in which telescopically derived photometric data, representing the map theme of albedo variation, is portrayed on a topographic base map prepared from scanner data obtained from a space probe. Digital image processing is employed in a wide range of tasks including data averaging and filtration, and grid and scale transformation. Two maps, representing different versions of final output, are provided: a map with albedo variation displayed according to the shaded-isoline technique, and one in which numerical values are printed over a grid of control points.

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。

PASS PROCESSING AND EXTRAPOLATION OF SPOT IMAGE GEOMETRY

A mathematical model for pass processing of SPOT imagery is formulated. It is based on the fact that during one pass, the image data stream from each of the instruments in SPOT forms one single very long image. The geometry of this extended image can thus be rectified with as few control points as for only one scene if orbital constraints and attitude measurements are properly taken into consideration. SPOT imagery is, however, not available as this single long image, but only sectioned into scenes. This creates problems which are accounted for in the solution. The possibility of gaps in the sequence of scenes is also taken into consideration. Extrapolation over gaps is of special interest and, by investigating attitude variability, it is shown that extrapolation is successful over multiple scene gaps which is also verified in a real data test.
