Linear Filtering of Images Based on Properties of Vision
V. Ralph Algazi - Gary E. Ford - Hong Chen
Abstract:
A new formulation is presented for the design of linear image filters,
based on some properties of human visual perception. For low pass
filters, this new formulation leads to introducing the concept of an
ideal low pass image filter which provides a response that is superior
perceptually to that of the classical ideal low pass filter. We also
consider anisotropic filters that provide some additional flexibility and
improved performance in the processing of images.
