Computer system and a method for segmentation of a digital image
First Claim
1. A method for segmentation of a digital image being represented by picture element data, the method comprising the steps of:
- performing a watershed transformation of the digital image by applying a watershed transformation method on the picture element data to provide one ore more basins, post-processing of at least one of the basins by processing the picture element data belonging to the at least one of the basins, where the post-processing is selected from the group of post-processing steps consisting of;
i. gray-scale based segmentation, ii. visualization using a transfer function, iii. volumetry using histogram analysis.

Abstract
A computer system and a method for segmentation of a digital image The invention relates to a method for segmentation of a digital image being represented by picture element data for the purposes of visualization, segmentation and quantification, such as determining the volume of a segment. The method comprises the steps of performing a watershed transformation of the digital image by applying a watershed transformation method on the picture element data to provide one or more basins and post-processing by processing the picture element data belonging to at least one of the basins, where post-processing is one or a combination of the following steps: (i) gray-scale based segmentation, (ii) visualization using a transfer function, or (iii) volumetry using histogram analysis.

14. A computer system comprising
a memory component for storing picture element data of a digital image, a first program component for performing a watershed transformation of the digital image by applying a watershed transformation method on the picture element data to provide one or more basins, a second program component for post-processing of at least one of the basins by processing the picture element data belonging to the at least one of the basins to provide one or more segments.
