Sentence examples for ridge orientation from inspiring English sources

The proposed work, in this paper, presents a mask that locates the core point simply from the ridge orientation map.

Uniform overexpression of the Sple isoform in both dorsal and ventral wing epithelia (using the C765-Gal4 driner in combination with a UAS-sple transgene) generates reproducible changes in hair and ridge orientation on both dorsal and ventral wing surfaces.

We hypothesized that Sple expression in the dorsal epithelium would alter hair polarity on the dorsal but not ventral wing surface but would change ridge orientation on both surfaces.

For example, uniform overexpression of the Sple isoform of the Prickle protein (i.e., pk-PC), a component of the Fz PCP pathway (Gubb et al. 1999), alters hair and ridge orientation on both the dorsal and ventral wing (Doyle et al. 2008).

(For cells in a chemotactic gradient, the CI is generally defined as the sum over cos for all cell velocities, where θ is the angle between the cell velocity and the needle direction. In contrast, for cells on ridges, we define the CI as the sum over cos(2θ) for all cell velocities, where θ is the angle between the cell velocity and the ridge orientation).

Local minutiae descriptors, which comprise ridge orientations and frequency information, are bound to ordinate values of a fuzzy vault applying a fuzzy commitment scheme.

Most fingerprint recognition systems use Level 1 characteristics (ridge flow, orientation, and frequency) and Level 2 features (minutiae points) to recognize individuals.

It uses the fact that if knowing ridge local orientation around applied pixels and applying adaptive filter, ridges with the same direction become clear.

The fingerprint ridge frequency and orientation were captured using short-time Fourier transform.

The next step is to encode the iris image from two dimensional brightness data down to a two dimensional binary signature, referred to as the template ("Template Generation" in Figure 2), to accomplish this, the energy data are passed into two directional filters to determine the existence of ridges and their orientation.

The metric encodes the continuity of the ridge spectrum along the orientation of strong ridges in the image.
