A novel MR image acquisition protocol has been presented in order to obtain high resolution image of the brain at acquisition time. For better delineation of the substructures of the brain we have emphasized enhancing the intensity difference between white and gray matters in the reconstructed MR image of the brain. The mathematical basis of the protocol stems from the T1 weighting combined with an...
The plasmon resonance conditions in nano-sized materials leads to local field enhancement resulting in amplified response of various linear and nonlinear optical processes at the nano-scale. In this paper, metallic nanoparticles are imaged using several modalities - brightfield, confocal reflectance, two-photon, and second harmonic generation. Two examples are discussed - Au nanoparticles in the zebrafish...
In this paper, an automatic segmentation technique of multispectral magnetic resonance image of the brain using a new line symmetry based genetic clustering technique is proposed. The proposed real-coded variable string length genetic clustering technique (VGALS clustering) is able to evolve the number of clusters present in the data set automatically. Here assignment of points to different clusters...
In this paper, an automatic segmentation technique of multispectral magnetic resonance image of the brain using a new fuzzy point symmetry based genetic clustering technique is proposed. The proposed real-coded variable string length genetic fuzzy clustering technique (fuzzy-VGAPS) is able to evolve the number of clusters present in the data set automatically. Here, assignment of points to different...
