Abstract
Machine vision methods for segmenting an image include the steps of generating a first image of the background of an object, generating a second image of the object and background, and subtracting the second image from the first image. The methods are characterized in that the second image is generated such that subtraction of it from the first image emphasizes the object with respect to the background.
