Autocorrelation fitting for texture orientation estimation

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
The problem of short-term texture orientation is dealt with in this paper through autocorrelation fitting. Actually, the computation of the estimated autocorrelation sequence from a textured oriented image brings about the apparition of an oriented pattern.

Estimating orientation with gyroscopes and accelerometers

Technology and Health Care, 1999
Many systems for recording human movement need some reference from beacons near the subject, such as video cameras. Our goal is to measure human kinematics with sensors that are placed on the segments of interest. This way, experiments in which human movement is recorded are not restricted to a lab.

Orientation estimation of 3D surface Patches

Computer Vision, Graphics, and Image Processing, 1990
Abstract Orientation estimation of a surface patch is an essential step in an automatic inspection job or a 3D template matching scheme for object recognition. Two main problems of the estimation are non-uniform surface sampling and self-occlusion. To solve these problems, we propose to use a 3D spherical window to extract the correct patch and to ...

Pedestrian Orientation Estimation

2014
This paper addresses the task of estimating the orientation of pedestrians from monocular images provided by an automotive camera. From an initial detection of a pedestrian, we analyze the area within their bounding box and give an estimation of the orientation.

Estimation of seafloor electromagnetic receiver orientation

GEOPHYSICS, 2012
If the orientation of a seafloor electromagnetic (EM) instrument is unknown, it has to be estimated afterwards, relatively early in the processing. Here we present a method to estimate the horizontal and vertical orientation of seafloor electromagnetic receivers.

Orientation Estimation Network

2017
We propose the Orientation Estimation Network (OEN) to predict the dominant orientation of the outdoor images and rotate the images to a canonical orientation which is visually comfortable. The OEN outputs the sine and cosine of the angle which are continuous in contrast to the angle.

Orientation-Aware Regression for Oriented Bounding Box Estimation

2018 15th IEEE International Conference on Advanced Video and Signal Based Surveillance (AVSS), 2018
Oriented bounding box estimation is an essential element for object detection since objects in real images consist of multiple orientations. State-of-the-art bounding box regression utilize linear layers and ReLU activations with an oriented feature as input, however these methods do not directly use the feature orientation.

Population codes for orientation estimation

Proceedings 15th International Conference on Pattern Recognition. ICPR-2000, 2002
Population coding has become an essential paradigm in cognitive neuroscience over the past decade and is increasingly studied within the neural network community. We investigate the use of population vector decoding for local edge orientation estimation from a discrete set of Gabor filters.

Estimating sensor orientation in cameras

Proceedings 15th International Conference on Pattern Recognition. ICPR-2000, 2002
For most imaging cameras, it is desirable that the sensor plane be perpendicular to the optical axis. Such an orientation ensures that the imaging configuration is perspective and planar scene objects perpendicular to the optical axis can be focussed in their entirety.
