this paper describes an efficient edge-preserved regularization algorithm for downward continuation of magnetic data in detection of unexploded ordnance (uxo). the magnetic anomalies arising from multi-source uxo can overlap at a height over the ground surface, while causative sources may not be readily separated due to low level of signal-to-noise ratio of the observed data. to effectively the...

This paper proposes a noise smoothing algorithm for dense range image using adaptive regularization, which preserves discontinuities and removes noise, simultaneously. In order to obtain the discontinuity-preserved range data, both high frequency components across the edge orientation and smoothness along the edge orientation are considered in this algorithm. As a result, the proposed algorithm...

This paper presents an adaptive regularized image interpolation algorithm from blurred and noisy low resolution image sequence, which is developed by a general framework based on data fusion. This framework can preserve edge information and suppress noise, effectively. To obtain a higher resolution image, both discontinuities across the edge orientation and smoothness along the edge orientation...

We present a fully dynamic algorithm for split graphs that supports the following types of operations: (1) query whether deleting or inserting an edge preserves the split property, (2) query whether inserting a new vertex with a given neighborhood in the current graph preserves the split property, (3) insert or delete an edge or a vertex when the split property is preserved, (4) insert an edge ...

background: a method to track liver tumor motion signals from fluoroscopic images without any implanted gold fiducial markers was proposed in this study to overcome the adverse effects on precise tumor irradiation caused by respiratory movement. materials and methods: the method was based on the following idea: (i) before treatment, a series of fluoroscopic images corresponding to different bre...

Edges produced by existing edge detection algorithms often contain discontinuities. Edge linking as a post-processing step is very important for computer vision and pattern recognition. Nevertheless, subject to the lacking of information in the image, difficulties arise when it is tackled. The clonal selection algorithm (CSA), inspired by the basic features of adaptive immune response to antige...

A graceful labeling of a graph $G=(V,E)$ with $m$ edges is aninjection $f: V(G) rightarrow {0,1,ldots,m}$ such that the resulting edge labelsobtained by $|f(u)-f(v)|$ on every edge $uv$ are pairwise distinct. For natural numbers $n$ and $k$, where $n > 2k$, a generalized Petersengraph $P(n, k)$ is the graph whose vertex set is ${u_1, u_2, cdots, u_n} cup {v_1, v_2, cdots, v_n}$ and its edge set...
