Sentence examples for contours level from inspiring English sources
Active contours or deformable models are generally divided into two types: parametric active contours (typically known as snakes) and geometric active contours (level set).
While the former generally suffers from the difficulty of naturally handling topological changes for the splitting and merging of contours, level set handles this in a natural fashion.
By comparative performance analysis with state-of-the-art image segmentation methods such as active contours (level set), K-means clustering, non-negative matrix factorization, ICA and ratio imaging we experimentally demonstrate good performance of DCA-based BCC demarcation in two demanding scenarios where intensity of the fluorescent image has been varied almost two orders of magnitude.
The edge potential image along with the initial level set was then used directly in the geodesic active contours level-set filter.
Finally, the output of the geodesic active contours level-set filter acted as an initial level-set input for the Laplacian level-set filter.
The relative weights of the propagation, curvature, and advection terms of the geodesic active contours level-set filter were set to −10, 1.0, and 1.0, respectively.
A low contour level, however, may include excessive noise, introducing errors into phase calculations. .
Three states were filtered to 8 Å (at 3σ contour level).
A low contour level, however, may include excessive noise, introducing errors into phase calculations.
A high contour level may exclude potential real density, resulting in missing structural information.
