Sentence examples for a main orientation from inspiring English sources

After extracting Lowe's keypoints in SIFT, a main orientation is assigned to the points.

The determined rotation and scaling in effect serve as a main orientation for the entire image when used as computing descriptors.

A main orientation is assigned to a keypoint, and the local gradient pattern with respect to the main orientation is computed as its descriptor.

However, for a window of a larger size on multispectral images, correctly assigning a main orientation is itself a challenging task [22].

In the latter case, the texture can be rotated to a main orientation or principal direction, see e.g. [2] where the Radon transform is used to accomplish this, or alternatively, a texture descriptor invariant to rotation can be used.

The axonal polar plot for L6B pyramidal neurons shows a main orientation towards the pial surface (polar plot angles: 0 ± 30°; Fig.  4 A2).

Note the superscript T of ({E_{t}^{T}} x,y)) in (5) is a generalized version of main orientation.

We determined the position of each population with a GPS, counted the number of cushions, noted whether it occurred on a rock face, a scree or a stone wall, and estimated its main orientation as the absolute deviation from north in degrees.

The main orientation of a keypoint accounts for the local geometric view difference with rotation.

As building objects are expected to be connected with each other on a regional level, exploiting the main orientation obtained from the local gradient analysis provides further information for detection purposes.

In the head of the primate caudate nucleus, Walker et al. (1993) have shown that there exists a predominant dorsomedial to ventrolateral orientation of the dendritic arborizations of MSN, an orientation that parallels the main orientation of the striosomes in this part of the striatum.
