We have discussed that the co-occurrence frequency image (CFI) defined based on the co-occurrence frequency histogram of the gray value of an image has a potential to introduce a new scheme for image feature extraction. This paper proposes a couple of filters for image enhancements of such as sharpening and smoothing filters. These filters are very similar to but quite different from those which have been used so far. Thus we could show a possibility for introducing a new paradigm for basic image enhancement filters based on CFI.
