Diffusion tensor imaging (DTI) offers an efficient evaluation over microstructure of white matter integrity. In this study, we aim to study the white matter tracts, which are associated with normal ageing. 42 healthy subjects were included, which is composed of two groups. One is young subjects (age = 22.29±1.35), and the other is elder (age = 63.71±2.00). Statistical analysis over FA was carried...
Wavelet transform is widely used in feature extraction of magnetic resonance imaging. However, the traditional discrete wavelet transform (DWT) suffers from translation variant property, which may extract significantly different features from two images of the same subject with only slight movement. In order to solve this problem, this paper utilizes stationary wavelet transform (SWT) to extract features...
