1. A method of detecting a foaming contaminant in a moving container, comprising:
- producing an image of at least a portion of the interior of the moving container and any contents thereof,determining a level of low frequency spatial variations in intensity in the image,determining a level of high frequency spatial variations in intensity in the image, anddetermining the presence of a foaming contaminant by comparing the level of low frequency spatial variations in intensity to the level of high frequency spatial variations in intensity.

Abstract
To detect a foaming contaminant in a moving container, an image of the moving container and any contents thereof is produced. Thereafter, image processing techniques are used to determine levels of low and high frequency spatial variations in intensity in the image. The levels of low and high frequency spatial variations in intensity are then compared to determine the presence of a foaming contaminant.
