Abstract

An analysis of clutter in IR background images was performed on image data videotaped in the southern USA and on a variety of IR image data from other sources. Images collected in the southern USA area, the Rome NY area and in central Europe were included in the study. The clutter in the images was computed as the rms noise in the pixel levels over the image. The images were subjected to spatial filtering procedures and the clutter calculations were repeated on the filtered images. Spectral densities were computed for the images in both filtered and unfiltered states to obtain information on the spatial frequency content of IR images of background scenes. The computed clutter values were entered into a data base and sets of data were extracted and plotted to determine the influence of parameters such as weather, scene type and measurement conditions on the clutter level of an image.
