Abstract :
The design of 2-D finite impulse response (FIR) digital filters is presented for two-dimensional sampling structure conversion. Both the sampling structure model and the filter characteristics have been chosen to cover a large class of problems related to multidimensional linear processing for video signals. Optimal infinite and finite precision filter design methods are proposed. Experimental analysis concerning the effects of coefficient rounding on the filter frequency response was carried out, which was found to be consistent with previous theoretical results. A simulation with one test picture is presented to illustrate the problem of sampling structure conversion
