The use of Richardson–Lucy deconvolution to recover a signal blurred by an impulse response function. The Richardson–Lucy algorithm, also known as Lucy–Richardson deconvolution, is an iterative procedure for recovering an underlying image that has been blurred by a known point spread function.
Deblurring is the process of removing blurring artifacts from images. Deblurring recovers a sharp image S from a blurred image B , where S is convolved with K (the blur kernel ) to generate B . Mathematically, this can be represented as B = S ∗ K {\displaystyle B=S*K} (where * represents convolution ).
Lightroom is non-destructive editing software that keeps the original image separate from its edits, saving the edited image as a new file. While Photoshop includes doctoring functions like adding, removing or altering the appearance of individual image items, rendering text or 3D objects on images, or modifying individual video frames, Lightroom is a library and development software.
The program is a command line tool which takes a list of raw image files to process, along with any image adjustment options desired. dcraw also serves as the basis for various high-level raw image-processing applications (such as viewers and converters), both free and open source software as well as proprietary software.
As with Adobe Acrobat, Nitro PDF Pro's reader is free; but unlike Adobe's free reader, Nitro's free reader allows PDF creation (via a virtual printer driver, or by specifying a filename in the reader's interface, or by drag-'n-drop of a file to Nitro PDF Reader's Windows desktop icon); Ghostscript not needed.
