ABSTRACT:
An adaptive filter that, in one embodiment, filters rows of pixels of an image in a vertical direction, stores the results in row vectors, and then filters the row vectors in the horizontal direction, and displays the results or stores the results for later display. Coefficients of a reference filter are modified based on the output from the reference filter through a table-lookup process that accesses tables of modified filter coefficients. The output of the modified filter is added to a delayed version of the input to provide the adaptive filter output.
