There was an interesting paper on this very subject at ECCV (European 
Conference on Computer Vision) in 1994.

"Area and Length Preserving Geometric Invariant Scale-Spaces"
by G Sapiro and A. Tannenbaum, in Proc. of ECCV 94 (Springer-Verlag) 
vol2 p449-459

The paper concentrates on area-preserving smoothing but also
deals with length-preserving geometric smoothing.

Hope this helps.
