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 ).
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.
Unsharp masking (USM) is an image sharpening technique, first implemented in darkroom photography, but now commonly used in digital image processing software. Its name derives from the fact that the technique uses a blurred, or "unsharp", negative image to create a mask of the original image. The unsharp mask is then combined with the original ...
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.
Camera or computer image editing programs often offer basic automatic image enhancement features that correct color hue and brightness imbalances as well as other image editing features, such as red eye removal, sharpness adjustments, zoom features and automatic cropping.
