Andronico A., Bastianini G., Casalini P., Tonazzini A. Implementation of a digital filter having transfer function sinc. Internal note IEI-B82-26, 1982.
In this paper we discuss an approach to the image digital filtering. By a formal point of view, the subject is ideal t with as a numerical simulation of the corresponding analog procedure. So wie study some aspects of the implementation of three kinds of filters FIR(low-pass, band-pass, high-pass) having transfer functions sinc u. Then we report exemples of filtering on test images, for which the behavior of the filters in the frequency domain is analitically foreseeable.
