This study aims at obtaining smoothed strain fields from
digital image correlation technique (DIC), by smoothing
the displacement fields prior to strain computation. Both
median absolute deviation (MAD) and mean absolute
deviation based smoothing algorithms are implemented for
data smoothing. On implementation of these algorithms,
the noise levels in the strain fields are found to be reduced
to a greater extent. For executing the whole field
smoothing algorithm, an accurate boundary encoding
algorithm is also developed
