Abstract:

An image may be considered to be a finite extent two dimensional sequence with truncation occuring at the edges of the image. The corresponding data set is equivalent to the product of a two dimensional rectangular window function and an infinite duration two dimensional function. The edge transients associated with data truncation can propagate throughout the output image when infinite impulse response spatial domain filters are used. These transient effects can completely obscure the output image with certain types of filters. This paper presents a technique which can be used to eliminate the edge transients associated with data truncation for spatial domain filter applications.
