Image processing methods, which can visualize objects inside the human body, are of special interests. In clinical diagnosis using medical images, integration of useful data from separate images is often desired. The images have to be geometrically aligned for better observation. The procedure of mapping points from the reference image to corresponding points in the floating image is called Ima...
Functional near-infrared spectroscopy (fNIRS) has now become widely accepted as a common functional imaging modality. In order for fNIRS to achieve genuine neuroimaging citizenship, it would ideally be equipped with functional and structural image analyses. However, fNIRS measures cortical activities from the head surface without anatomical information of the object being measured. In this revi...
In this paper we assess rigid body co-registration in terms of residual motion artifacts for the different correlation approaches used in fMRI. We summarise, from a statistical perspective, the three main approaches to parametric fMRI analysis and then present a new way of visualising motion effects in correlation analysis. This technique can be used both to select regions of relatively unambig...
Background and Objectives: The distribution of causes of death indicates the distribution of risk factors for death, and is a basis of planning and intervention to reduce risk factors. The quality of the registered information has problems due to the weakness of the processes of completing and issuing the death certificate or the coding method. The purpose of this study was to explain the chall...
functional magnetic resonance imaging (fmri) has become the most popular method for imaging of brain functions. currently, there is a large variety of software packages for the analysis of fmri data, each providing many features for users. since there is no single package that can provide all the necessary analyses for the fmri data, it is helpful to know the features of each software package. ...
Precise co-registration of panchromatic and multispectral images can be challenging due to the imperfect alignment of different sensors from the same platform or the involvement of different platforms. However, conventional methods heavily depending on the quality of feature matching and parameterized model fitting fail to yield an accurate result if the relative deformation between images is l...
