In this paper, we compared the performance of a number of Diffusion Tensor Imaging (DTI) pre-processing tools on a dataset of chronic subcortical stroke patients during rehabilitation exercise. In the comparison, acquired Diffusion-Weighted Images (DWI) are pre-processed by different pipelines, which compose of different DTI pre-processing tools, independently. And a DTI measure, FA (fractional anisotropy),...
Automatic face location in complex scenes is extremely challenging in human face recognition system. The accuracy of the location is also a critical factor to the recognition performance. This paper presents a scheme to accurate eye detection from face sequences. After detecting the preattentive features by using the Gaussian steerable filter, face models are investigated to locate the whole face...
Audio signal is an important clue for the situation awareness. It provides complementary information for video signal. For home care, elder care, and security application, screaming is one of the events people (family member, care giver, and security guard) are especially interested in. We present here an approach to scream detection, using both analytic and statistical features for the classification...
