An edge-based algorithm for discontinuity adaptive color image smoothing

We present a new scheme to increase the performance of edge-preserving imag e smoothing algorithm from the parameter tuning of a Markov random field (M RF) function. This method is based on an automatic control of the image-smo othing strength in the MRF function in which the parameter control of the f unction depends on edge magnitude resulted from discontinuities of image in tensity. Without any binary decision for the edge magnitude, direct use of full edge magnitude could improve the performance of discontinuity-preservi ng image smoothing technique.
