de·con·vo·lu·tion

(dē'con-vō-lū'shŭn),
1. A mathematic technique for solution of functions whose input includes their output; used to solve for the image elements in computed tomography or magnetic resonance imaging.
2. Computer-based process for enhancing image definition in microscopy.
[de- + L. convulutio, a rolling up, fr. convolvo, to roll up]

While most astrophotographers have success improving their images using standard sharpening tools like the popular Unsharp Mask tool in Adobe Photoshop, they often report that deconvolution either didn't work or made their images appear worse.
Deconvolution is the name of the process that restores the initial signal from the convolved signal with a known convolution kernel.
Deconvolving at varying values of Disk radius and number of blind deconvolution iterations.
Such processing steps could involve deconvolution (Schmid and Huisken, 2015) and projections (Schmid et al.
AMDIS (Automated Mass Spectral Deconvolution and Identification System) is deconvolution software that not only identifies the hidden compounds but also speeds up the evaluation of GC/MS based full-scan analysis.
The components of cellulose I and cellulose II were determined from three, four reflections by the deconvolution of the WAXD curves (OH et al.
This instability is a characteristic of inverse problems, such as deconvolution, and it has to do with the fact that the forward mapping (convolution) is a compact operator defined on a function space [5].
The structure of this paper is as follows: Section 2 describes the proposed millimeter wave radar system configuration for detection of potential suicide bombers; Section 3 describes the signal processing algorithm for creating the SAR images when the system works in a Multiple-Frequency-Multiple-Transmitter-Multiple Receivers configuration; Section 4 presents a deconvolution algorithm to remove the PSF response from the SAR image; Section 5 introduce the numerical results for a suicide bomber with and without metallic pipes and dielectric rods; in Section 6 the conclusions and major contributions on the paper are described.
In addition, detailed deconvolution of the MWDs of PBs produced with neodymium versatate catalysts are reported here for the first time, indicating that three or more catalyst sites are required to explain the final MWD of the polymer samples.
Inorganic P in the NaOH-EDTA extracts was also quantified using deconvolution of 31p NMR spectra (detailed below).
Moreover, after deconvolution of the spectra a signal at 15.
