Abstract
Changing illumination constitutes a serious challenge for video segmentation

algorithms, especially in outdoor scenes under cloudy conditions.

Rapid illumination changes, e.g. caused by varying cloud cover,

often cause existing segmentation algorithms to erroneously classify

large parts of the image as foreground.

Here a method that extends existing segmentation algorithms by

detecting illumination changes using a CUSUM detector and adjusting

the background model to conform with the new illumination is

presented. The method is shown to work for two segmentation algorithms,

and it is indicated how the method could be extended to other

algorithms.
