In this framework, we first segment the brain using a method adapted for pathological cases and extract some global information on the tumor by symmetry based histogram analysis. ...
For tumor segmentation, we propose a framework that is a combination of region-based and boundary-based paradigms. ...
Hence, it is required to normalize interslice intensity to have a correct 3D segmentation. Here a method based on scale-space analysis of histogram is used [9] .
