This paper describes an algorithm for human tracking using vision sensing, specially designed for a human machine interface of a mobile robotic platforms or autonomous vehicles. The solution presents a clear improvement on a tracking algorithm achieved by using a machine learning approach for visual object detection and recognition for data association. The system is capable of processing image...

In neuroimaging, functional mapping usually implies mapping function into an anatomical space, for example, using statistical parametric mapping to identify activation foci, or the characterization of distributed changes with spatial modes (eigenimages or principal components) (Friston et al., 1993a). This article is about a complementary approach, namely, mapping anatomy into a functional spac...

This thesis describes a system for extracting three-dimensional models from two-dimensional images over the restricted domain of frontal images of human faces. A three-dimensional face model template is fit to a three-dimensional digitizations of a set of training subjects. The standard-form models allow different subjects to be treated in a uniform manner. The particular template model chosen ...

When an airbag deploys on a rear-facing infant seat, it can injure or kill the infant. When an airbag deploys on an empty seat, the airbag and the money to replace it are wasted. We have shown that video images can be used to determine whether or not to deploy the passenger-side airbag in a crash. Images of the passenger seat, taken from a video camera mounted inside the vehicle, can be used to...

Title of dissertation: MULTISCALE ANALYSIS AND DIFFUSION SEMIGROUPS WITH APPLICATIONS Karamatou Yacoubou Djima Doctor of Philosophy, 2015 Dissertation directed by: Professor Wojciech Czaja Mathematics Department Multiscale (or multiresolution) analysis is used to represent signals or functions at increasingly high resolution. In this thesis, we develop multiresolution representations based on f...

BACKGROUND Both major depressive disorder (MDD) and post-traumatic stress disorder (PTSD) are characterized by alterations in intrinsic functional connectivity. Here we investigated changes in intrinsic functional connectivity across these disorders as a function of cognitive behavioral therapy (CBT), an effective treatment in both disorders. METHODS 53 unmedicated right-handed participants w...

Object Detection with Vector Quantized Binary Features John Krumm Intelligent Systems & Robotics Center Sandia National Laboratories Albuquerque, NM 87185 [email protected] Abstract This paper presents a new algorithm for detecting objects in images, one of the fundamental tasks of computer vision. The algorithm extends the representational efficiency of eigenimage methods to binary features, ...

Traditional content based image indexing aims at developing algorithms that can analyze and index images based on their visual content. A typical approach is to measure image attributes, like colors or textures, and save the result in image descriptors, which then can be used in recognition and retrieval applications. Two topics within content based image indexing are addressed in this thesis: ...

Glossary Block Design: Experimental design for functional neuroimaging in which an attempt is made to put the subject's brain in a steady state of activity by using the same type of task for an extended period, of time (typically 20-60 seconds), and then comparing the brain activation during that block with other blocks which use a different task. BOLD (Blood Oxygen Level Dependent): Refers to ...
