New Multiscale Transforms, Minimum Total Variation Synthesis: Applications to Edge-Preserving Image Reconstruction
Ridgelets curvelets wavelets pseudo-polar FFT Slant Stack Radon transform trigonometric interpolation total-variation edges edge-preserving tomography/deconvolution thresholding
2015/6/17
This paper describes newly invented multiscale transforms known under the name of the ridgelet [6] and the curvelet transforms [9, 8]. These systems combine ideas of multiscale analysis and geometry. ...

In this paper we investigate the vertex chromatic number, the edge chromatic number, and the total chromatic number in Spider graphs.
Edge detection techniques: Evaluations and comparisons
image processing edge detection Euclidean distance
2010/9/13
Edge detection is one of the most commonly used operations in image analysis, and
there are probably more algorithms in the literature for enhancing and detecting edges
than any other single subject...
Let G(V,E) be a simple graph, the edge-binding number b1 (G) of G is defined as where N(S) denotes the adjacent edges set of S. In this paper, we obtained the edge-binding number of outer plane graphs...
An m-restricted edge cut is an edge cut that separates a connected graph into a disconnected one with no components having order less than m. m-restricted edge connectivity λ_m is the cardinality of a...
A TIGHT LOWER BOUND ON THE MAXIMUM GENUS OF 3-EDGE CONNECTED LOOPLESS GRAPHS
Maximum genus 3-edge connect
2007/12/10
It is shown that the lower bound on the maximum genus of a 3-edge connected loopless graph is at least one-third of its cycle rank. Moreover, this lower bound is tight. There are infinitely such graph...
