@nikie That doesn't seem to work as replacement of Dilation. You could try that with the above example, yielding this, which is not the same result.

comment Grayscale Morphology
I may be mistaken here, but I always thought that the definition of the dilation and erosion operators required the kernels to be binary. Dilation picks the maximum value of all the image pixels below the 1's in the kernel for every location the kernel is placed on. Non-binary values would not make sense in this context. Perhaps you are looking for another operation like ImageConvolve?

Not an explanation you're asking for, but just an observation: Giving b a starting value of -1 yields the correct answer.

comment How to plot planar graphs as such?
@juan Functions can be entered in Mathematica in a standard format with fun[arg], prefix form as fun@arg, infix as arg1~fun~arg2, and postfix form as arg//fun. Sometimes, one of the forms is more convenient or fits more with your mental image of the program flow. Note that precedence of the various forms differs.

comment How to plot planar graphs as such?
@Juan Why wouldn't that be the case? GraphData graphs are just graphs. Try for instance Graph[GraphData[{"TriangularHoneycombObtuseKnight", 5}] // EdgeList // Graph, GraphLayout -> "PlanarEmbedding"]
