Abstract
AbstractA parallel algorithm for reducing impulse noise
from color images is proposed. The algorithm is based on a
fuzzy metric and is performed in two steps followed by noise
filtering using the vector median filter. An implementation of
the algorithm on multi-core interface using the Open Multi-
Processing (OpenMP) is presented. A performance analysis
with large images is conducted. Performance is evaluated in
terms of execution time and in terms of PSNR. Results show
that the proposed filter obtains good performance in terms of
PSNR. After applying the multicore optimization strategies,
the observed time shows that the proposed filter is able to
remove impulse noise in real-time.
