Abstract

There is provided a method and an apparatus for updating a background model used for background subtraction of an image. An image (220) is received and each pixel in the image is classified as being foreground (232) or background (234) by performing background subtraction using a background model which comprises a collection (240) of background samples for each pixel in the image (220). For each pixel (228) in the image being classified as background (234), the background model is updated by selecting a background sample (242) in the collection of background samples associated with the pixel which fulfils a similarity condition, and replacing the background sample (242) which fulfils the similarity condition with image data of the pixel (228).
