A 3D fuzzy-filtering scheme is proposed for reduction of compression artifacts such as blocking and ringing noises. The
proposed scheme incorporates information from temporally-neighboring frames as well as from spatially-neighboring
pixels by accounting for the spatio-temporal relationships in the definitions of spatial-rank orders and spread information
for the fuzzy-filter. Extra information from a 3D set of pixels of the surrounding frames helps enhance the clustering
characteristic of the fuzzy filter while preserving the frame edges. The proposed scheme also exploits the chroma
components from neighboring frames to reconstruct the color of the current frame more faithfully. The experimental
results show that both the subjective and the objective qualities of post-processed video are significantly improved.
