چکیده
A large number of attitude estimation algorithms assume sensor placement along the axis of rotation. These models assume that all measured accelerations are due to gravity, while in reality this is not always the case. By expanding the system model to accommodate centrifugal and tangential accelerations the attitude can be more accurately estimated. This thesis introduces an approach to model accelerations not caused by gravity. This model is incorporated into a Kalman filter and then compared with the more conventional Kalman filter approach which assumes all system acceleration is due to gravity.

An Improved Motion Vector Estimation Approach for Video Error Concealment Based on the Video Scene Analysis
In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...
متن کاملRecursive Estimation of Motion and Planar Structure
A specialized formulation of Azarbayejani and Pentland's framework for recursive recovery of motion, structure and focal length from feature correspondences tracked through an image sequence is presented. The specialized formulation addresses the case where all tracked points lie on a plane. This planarity constraint reduces the dimension of the original state vector, and consequently the numbe...
