On Edge Coloring Bipartite Graphs [PDF]
SIAM Journal on Computing, 1982 The present paper shows how to find a minimal edge coloring of a bipartite graph with E edges and V vertices in time $O(E\log V)$.

AbstractWhen can a k‐edge‐coloring of a subgraph K of a graph G be extended to a k‐edge‐coloring of G? One necessary condition is that for all X ⊆ E(G) ‐ E(K), where μi(X) is the maximum cardinality of a subset of X whose union with the set of edges of K colored i is a matching.

Pattern Recognition Letters, 1985
The detection of visually significant edges and boundaries in a natural color image is complicated by inherent noise and correlation between color coordinates. In this letter we present a color edge detector which uses fuzzy set theory to model this imprecision.

ColorED: Color edge and segment detection by Edge Drawing (ED)
Journal of Visual Communication and Image Representation, 2017Abstract We extend our recent edge and segment detector, Edge Drawing (GrayED), to detect edge segments in color images. Edge Drawing for color images, named ColorED, takes in a color image, and outputs a set of edge segments, each a contiguous, 1-pixel wide chain of pixels.

We consider the following channel assignment problem arising in wireless networks. We are given a graph G= (V, E), and the number of wireless cards C v for all v, which limit the number of colors that edges incident to vcan use. We also have the total number of channels C G available in the network.
