Symptoms of Parkinson's disease can be relieved by deep brain stimulation (DBS), which is based on an accurate positioning of electrodes in specific structures of the basal ganglia, e.g. the subthalamic nucleus (STN) and the internal globus pallidus (GPi), and of the thalamus. We planned to develop an automatized method for the identification of these structures, deeply located in the brain, through...
A fuzzy modelling approach is being proposed in this paper to estimate the model of tumorous cerebral tissues on MRI images . According to the graduality of description of neuro-radiologists, two tables have been combined to address two types of potential categories of glioma characteristics one is the array of different tissues versus gray level, and the other is the possibility of different tissues...
In order to help clinicians with the diagnosis of neurodegenerative diseases, we provide a synthetic functional information located in relation with anatomical structures. The final image is processed by multimodal data fusion between SPECT and MR images. We propose a new method for the management of such multiresolution data, in which a geometrical model allows an accurate correspondence of voxels...
In this paper, a region level based image fusion technique, using wavelet transform, has been implemented and analyzed. The proposed methodology considers regions as the basic feature for representing images and uses region properties for extracting the information from them. A segmentation algorithm is proposed for extracting the regions in an effective way for fusing the images. The fusion strategy...
