Estimating local multiple orientations [PDF]
Signal Processing, 2007 This paper focuses on the estimation of local orientation in an image where several orientations exist at the same location and at the same scale. Within this framework, Isotropic and Recursive Oriented Network (IRON), an operator based on an oriented network of parallel lines is introduced. IRON uses only a few parameters.

Directional functions for orientation distribution estimation [PDF]
Medical Image Analysis, 2008 Computing the orientation distribution function (ODF) from high angular resolution diffusion imaging (HARDI) signals makes it possible to determine the orientation of fiber bundles of the brain. The HARDI signals are samples measured from a spherical shell and thus require processing on the sphere.

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.
