Abstract
An iterative Fourier transform algorithm (IFTA) is applied for multilevel i mage quantization. A spatial operator is introduced. based on local signal adaptation, which allows a flexible handling of the quantization noise, esp ecially near the medium quantization level. Examples are shown and comparis ons with other iterative Fourier transform algorithms are performed. (C) 19 98 Elsevier Science B.V. All rights reserved.
