Content based image pose manipulation
This thesis proposes the application of space-frequency transformations to the domain of pose estimation in images. This idea is explored using the Wavelet Transform with illustrative applications in pose estimation for face images, and images of planar scenes. The approach is based on examining …

Pose estimation using cascade trees
… As a second extension, I designed a system for pose estimation based on an array of cascades. I performed an evaluation of this system and compared to normalized cross-correlation.

INTELLIGENT PATH SEARCHING AND POSE ESTIMATION
… This thesis focuses on path searching and pose estimation for autonomous vehicle navigation. The thesis first studies multi-sensor pose estimation on the vehicle that is equipped with cameras, an altitude and heading reference system (AHRS), and digital maps. The proposed pose estimation …

Joint Pose and Radio Channel Estimation
This thesis investigates the combination of pose and radio channel estimation. Pose is the knowledge of the position and orientation of a device whereas the radio channel describes the transmission medium between radio transmitters and receivers. The two subjects are both active research topics …

Computation of Suitable Grasp Pose for Usage of Objects Based on Predefined Training and Real-time Pose Estimation
… humanoid robots with different types of grasp poses. We present a grasping mechanism using homogeneous transformation that allows a humanoid robot to grasp objects in such a way that is suitable for the usage of the objects. The system captures the relative poses of an object and a robot's …

Body Pose Predictions in Triadic Social Interactions
Human beings are social animals in that they need to socialize with each other to build companionship and thrive alongside other humans. One of the primary characteristics of social interactions is the signals used by people to communicate their thoughts effectively. These include gesturing with …

Multiple relative pose graphs for cooperative mapping
… and mapping (SLAM) using multiple robots. Recent pose graph representations have proven very successful for single robot mapping and localization. Among these methods, iSAM (incremental smoothing and mapping) gives an exact incremental solution to the SLAM problem by solving a full nonlinear …

A deeper look at hand pose estimation
Hand pose recognition is a fundamental human ability and an important, yet elusive, goal for computer vision research. One of the major challenges in hand pose recognition is the sheer scale of the problem. The human hand is a notoriously agile object with 27 degrees of freedom. In a sense, it is …

Estimating Global Object Pose from Tactile Images
This work evaluates Tac2Pose, an object-specific approach to tactile pose estimation for known objects. Given the object geometry, we learn a perception model in simulation that estimates a probability distribution over possible object poses given a tactile observation. To do so, we simulate the …

Pose estimation using overhead imagery and semantics
As hardware improves, so does the ability to run more complex algorithms. Improvements in the portability and performance of computing units has allowed for more compact robotic systems such as Micro Aerial Vehicles (MAVs), while developments in camera technologies has allowed for the generation of …

Pose: Scalable General-Purpose Parallel Discrete Event Simulation
We propose a novel environment for PDES that facilitates the development of highly parallel models and requires minimal understanding of parallel computing concepts. We propose four primary approaches to improving the performance of PDES. We first examine the overhead required for synchronizing …

Vision-based trailer pose estimation for articulated vehicles
… behind the truck or tractor, and one of two proposed image processing methods: template-matching and Parallel Tracking and Mapping (PTAM). The PTAM-based method was shown to be the more accurate and versatile method in full-scale vehicle tests. RMS measurement errors of 0.4-1.6$^\circ$ were …
