Abstract
Image enhancement using Fourier transform coefficient rooting (often referred to as alpha-rooting) suffers from certain objectionable artifacts due to the processing. Such artifacts are caused by well-defined high contrast edges within the image. A modification of the usual alpha-rooting process is proposed whereby these artifacts are suppressed while the desirable enhancement features of the processing are retained.
