چکیده

In this short paper, we describe the tractography method based on the intrinsic unscented Kalman filer (IUKF) [1]. This method is a generalization of unscented Kalman filter (UKF) and involves the use of intrinsic geometry of the space of symmetric positive definite matrices denoted henceforth by Pn. In this filter, operations that are intrinsic to Pn are employed and thus no explicit constraints are needed to guarantee the positive definiteness of the estimated diffusion tensors unlike in [2]. This method is applied to the given human brain data to perform tractography and recover the CST.

Doppler and bearing tracking using fuzzy adaptive unscented Kalman filter

The topic of Doppler and Bearing Tracking (DBT) problem is to achieve a target trajectory using the Doppler and Bearing measurements. The difficulty of DBT problem comes from the nonlinearity terms exposed in the measurement equations. Several techniques were studied to deal with this topic, such as the unscented Kalman filter. Nevertheless, the performance of the filter depends directly on the...

A Full Bi-Tensor Neural Tractography Algorithm Using an Unscented Kalman Filter

We describe a technique that uses tractography to visualize neural pathways in human brains by using a framework which models the diffusion-weighted signal with overlapping Gaussian tensors. At each point on the fiber an unscented Kalman filter is used to find the most consistent diffusion direction as a mixture of previous estimates and of the local model. The approach was developed by extendi...
