ABSTRACT:
A method and a filter for continuous two-dimensional filtering of discrete m*n data to be processed having n lines each containing m data samples. The filter includes a horizontal filter HF and a vertical filter VF for performing the filtering as successive horizontal and vertical filtering operations for data divided for the processing into blocks having y lines. The filter further includes a first memory M1 for storing horizontal-filtered data to be received from the horizontal filter, a second memory M2 for storing internal intermediate states of the vertical filter, and a timing and synchronizing block TSC for generating address signals A1, A2 and control signals C1, C2 for storing in the first memory and for reading therefrom as well as for storing in the second memory and for reading therefrom.
