Abstract:

Differences between recognized standardization, i.e. ANSI standards and common usage de-facto standards, occasionally lead to incompatibilities and inconsistencies. These often impede efforts to compile and execute supposedly standard software in a different hardware and software environment than that in which it was originally createdtargeted. One such instance is described herein as a service to persons who may one day be called upon to perform similar code porting. The code addressed in this example performs a statistical analysis of the background clutter content of imagery data. This analysis can be used to pre-select appropriate digital filtering algorithms to de-emphasize the predominant background and other clutter data. The original input data is RADAR imagery, but the statistical analyses are applicable to sources such as acoustical and video data as well. Code examples are included as appropriate to illustrate changes required.
