SRAF generation based on SGM/CTM contour line
Advanced Lithography, 2021With the continuous improvement of chip integration level, resolution enhancement techniques (RET) has become one of the important technologies to promote the continued development of process nodes, such as source mask optimization (SMO), optical ...

Contour line simplification method based on the two‐level Bellman–Ford algorithm
Trans. GIS, 2020The contour line is one of the basic elements of a topographic map. Existing contour line simplification methods are generally applied to maps without topological errors.

In this paper, we proposed a novel method for text line segmentation of Tibetan historical document image with uchen script based on contour tracking. Our method is mainly to segment the text lines from the image documents using the contour curve of the ...

Reconstruction of Contour Lines for Digitization of Contour Map
2021Contour map has contour lines that are significant in building a digital elevation model (DEM). During the digitization and preprocessing of contour maps, the contour line intersects with each other or breaks apart resulting in broken contour segments. These broken segments impose a greater risk while building DEM leading to a faulty model.

Contour tracking via on-line discriminative active contours
2014 IEEE International Conference on Image Processing (ICIP), 2014This paper presents a novel on-line AdaBoost based discriminative active contour tracking framework (ADACT) using level sets. First we build an on-line AdaBoost based appearance model to track and extract the rough target region, which provides important discriminative clues for our active contour model.

Line endings and subjective contours
Spatial Vision, 1988Subjective forms depend exquisitely on the shapes of the termini of the bars acting as inducers. In particular, they follow small stretches of contour at the termini. Subjective brightness effects without precise boundaries are generated when the termini are pointed.

Contour line extraction with wireless sensor networks
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005An algorithm to extract contour lines using wireless sensor networks is proposed for environmental monitoring in this work. In contrast to previous work on edge detection that is primarily concerned with the region of a certain phenomenon, contour lines ...

Sign determination of contour lines
Optics Communications, 1975Abstract With the usual techniques of contour lining no distinction is possible between elevations and depressions. This distinction is obtainable if two adjacent reference planes are used. The generation and exploitation of two adjacent contour line systems are described and discussed.
