In this paper, investigations of brain activity response from experimental works, based on optic flow and wavelet using near infrared spectroscopy are presented. The outcomes of our research project showed that optical flow is a proper technology for the investigation of brain activity based on near-infrared spectroscopy (NIRS). Our research also showed that the results in the temporal domain, spatial...
Magnetic resonance imaging (MRI) is a widely used method to obtain high quality medical image of the brain. Post-processing MR images with segmentation algorithms enhances the visualization and measurement of soft tissues and lesions. However, the conventional algorithms are not perfect and there are still some regions which are not partitioned accurately. In this paper, a new ant colony algorithm...
We propose a new approach for quantifying regions of interest (ROIs) in medical image data. Rotationally invariant shape descriptors (ISDs) were applied to 3D brain regions extracted from MRI scans of 5 Parkinson's patients and 10 control subjects. We concentrated on the thalamus and the caudate nucleus since prior studies have suggested they are affected in Parkinson's disease (PD). In the caudate,...
