Brain research typically requires large amounts of data from different sources, and often of different nature. The use of different software tools adapted to the nature of each data source can make research work cumbersome and time consuming. It follows that data is not often used to its fullest potential thus limiting exploratory analysis. This paper(More)
The free diffusion phenomena of water molecules occurs in the brain due to thermal energy, so we apply two magnetic field gradient pulses in brain tissue while it happens and we obtain a magnetic field signal associated to the statistical distribution displacement of the population of water molecules in the voxel. It allows the acquisition of a digital(More)
We propose a method to segment the lumen of the colon from computed tomography (CT) images. To do so, we use first and second order statistical moments. These moments provide us with a set of descriptors to characterize the homogeneity of regions inside the colon. The algorithm presented in this paper makes use of these values in a prediction-correction(More)
