Patent Images
1. A method of segmenting a image comprising:
- determining at least one signal value level of the potential signal value levels of the image along which to divide a fuzzy histogram into at least two measurement distributions, the histogram being based, at least in part, on the image, the at least one signal value level being the at least one of the potential signal value levels that produces a divided fuzzy histogram having, based on a measure of the multidimensional distance between each of the measurement distributions and their respective complements, an extreme value of one of distinctiveness and fuzziness; and
segmenting the image using the at least one signal value level.

Abstract
Embodiments of a fuzzy distinction based thresholding technique for image segmentation are disclosed. In one embodiment, at least one signal value level of the image is determined along which to divide a fuzzy histogram, the histogram being based, at least in part, on the image. The signal value represents a value which produces a divided fuzzy histogram with an extreme value of one of distinctiveness and fuzziness based on a measure of multidimensional distance between measurement distributions and their respective complements. The image is then segmented using the at least one signal value.
