Abstract

A method of thresholding a set of images of an object of interest taken at different relative axial positions, each image in the set of images comprising a plurality of pixels each pixel having an intensity. The method comprises determining based on the intensities of the pixels in plural images from the set of images a global intensity value for the set of images; determinging based on the intensities of the pixels in a first image from the set of images a local intensity value for the first image; establishing for at least one image intermediate the first and second images, a respective lower threshold that is dependent on at least the global intensity value and the local intensity value for the first image; and binarizing the at least one intermedite image according to the respective lower threshold to create a corresponding at least one mask for segmentation of the object of interest.
