Definition With background subtraction the background in an image is removed. Thus it is done when a very uniform background is needed (e. g. for PIV algorithms). Hereby only relatively sharp objects remain and the background is removed with morphological algorithms. A non-uniform background results from non-uniform illumination and/or image capturing.
