Similarity-Based Image Segmentation Determination of Brain/Liquor Ratio by Alzheimer Dementia

, 2008
. In the paper, we propose a similarity based image segmentation method, which takes the non-image information and the image characteristics and selects among a set of cases the case, which fits best to the current case.
