Various fixed or dynamically varying threshold techniques reported in literature treat all the blocks whose sum of absolute differences (SAD) lie below a particular threshold as(More)
A new approach for reconstructing noisy curves has been proposed in this paper. Direct use of curve fitting on the noisy data yields very poor results and so some form of smoothing is required to eliminate this noise.
