Orientation Estimation of Rotated Sonar Image Targets via the Wavelet Subimage Energy Ratio
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Precise orientation information facilitates target recognition of sonar images. Traditional orientation estimation methods, including the Hough transform method, have poor antinoise abilities, so they cannot achieve high estimation precision for sonar ...

The Interacting Multiple Model Filter and Smoother on Boxplus-Manifolds
Sensors, 2021 Hybrid systems are subject to multiple dynamic models, or so-called modes. To estimate the state, the sequence of modes has to be estimated, which results in an exponential growth of possible sequences.

A Theory of Multiple Orientation Estimation [PDF]
, 2006 Estimation of local orientations in multivariate signals (including optical flow estimation as special case of orientation in space-time-volumes) is an important problem in image processing and computer vision. Modelling a signal using only a single orientation is often too restrictive, since occlusions and transparency happen frequently, thus ...

A framework for estimation of orientation and velocity
Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004 The paper makes a short presentation of three existing methods for estimation of orientation tensors, the so-called structure tensor, quadrature filter based techniques, and techniques based on approximating a local polynomial model. All three methods can be used for estimating an orientation tensor, which in the 3D case can be used for motion ...
