Sentence examples for extract boundary from inspiring English sources

This method is based on the iterative preprocessing of training images which can extract boundary and detailed feature information of authentic training faces, thereby improving the peak-to-correlation energy (PCE) ratio of authentic faces and to be immune to intra-class variance and noise interference.

We extract boundary positions as described in Crombach et al. (2012b) : first, we determine a 10% strip (delimited by red lines) along the midline of the dorso-ventral axis (black line).

In recent years, many sophisticated transfer functions have been designed to extract boundaries and structures, such as intensity-gradient histogram and LH histogram.

(5) Boundary locating and refining: as proposed in previous works [ 1, 16, 17, 19], a skeleton operation is used to extract boundaries from potential regions.

Next, the four corner points were detected in the extracted boundary points.

Presented here is a signal decomposition method for extracting boundary effects from an operational deflection shape (ODS) of a structure under harmonic excitation.

The simulation uses the experimentally extracted boundary conditions via a 3-D Berkeley model that is set to be fully transient to account for the interactions in the velocity and temperature fields in the passenger compartment, which included interactions from turbulent flow, thermal buoyancy and the three modes of heat transfer conduction, convection and radiation.

Therefore, when the watershed transform is applied to the filtered edge strength image, the extracted boundaries are mostly the building boundaries.

More seriously, the extracted boundaries could be incomplete (e.g., opened) so special refinement should be taken to close the opened boundaries before attempting smooth and precise operations.

(B ) Extracted boundaries from wild-type embryos are classified by gene and time class (grey lines) and used to calculate median boundary positions (black line in upper panel).

Comparative experiments demonstrate that the proposed edge detection algorithm can extract object boundaries and inhibit non-boundary edges caused by textures on object surfaces.
