Adaptive Image Sharpening Method Using Edge Sharpness
This paper proposes a new method for automatic improvement in image quality through adjusting the image sharpness. This method does not need prior knowledge about image blur. To accomplish this work, the authors developed a new method for evaluating image sharpness without MTF. This is called image "edge sharpness* value. According to the subjective experiments, optimal edge sharpness value for...
متن کاملImage sharpening by morphological filtering
In this paper we introduce a class of morphological operators with applications to sharpening digitized grey valued images. We introduce t.he underlying partial differential equation (PDE) that governs this class of operators. For discrete implementations of the operator class! we show that instances utilizing a parabolic structuring function, have special properties that lead to an efficient i...
متن کاملPostprocessing method for suppressing musical noise generated by spectral subtraction
In this correspondence, we investigate whether musical noise, which often exists in speech enhanced using spectral subtraction, can be suppressed. Via exploiting some specific characteristics of human speech, we propose a method that can effectively suppress musical noise without noticeable effect on speech intelligibility. Performance assessments confirm that our method is effective.
متن کامل3D Image Sharpening by Grid Warping
A method for sharpening of 3D volume images has been developed. The idea of the proposed algorithm is to transform the 3D neighborhood of the edge so that the neighboring pixels move closer to the edge, and then resample the image from the warped grid to the original pixel grid. The proposed technique preserves image textures while making the edges sharper. The effectiveness of the proposed met...
متن کاملDownscaling cokriging for image sharpening
The main aim of this paper is to show the utility of cokriging for image fusion (i.e. increasing the spatial resolution of satellite sensor images). It is assumed that co-registered images with different spatial and spectral resolutions of the same scene are available and the task is to generate new remote sensing images at the finer spatial resolution for the spectral bands available only at t...
