Example of a deconvolved microscope image. In optics and imaging, the term "deconvolution" is specifically used to refer to the process of reversing the optical distortion that takes place in an optical microscope, electron microscope, telescope, or other imaging instrument, thus creating clearer images.
While this process is sometimes known as unblurring, deblurring is the correct technical word. The blur K is typically modeled as point spread function and is convolved with a hypothetical sharp image S to get B, where both the S (which is to be recovered) and the point spread function K are unknown. This is an example of an inverse problem.
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.
The process theory of composition (hereafter referred to as "process") is a field of composition studies that focuses on writing as a process rather than a product. Based on Janet Emig's breakdown of the writing process, [1] the process is centered on the idea that students determine the content of the course by exploring the craft of writing using their own interests, language, techniques ...
The algorithm assumes that the image consists of a number of point sources. It will iteratively find the highest value in the image and subtract a small gain of this point source convolved with the point spread function ("dirty beam") of the observation, until the highest value is smaller than some threshold.
Review makeup products: Pick a specific genre you want to review, like red lipsticks, and mention the reasons why it’s good or not so great by giving examples and comparing different brands. 26.
A writing process is a set of mental and physical steps that someone takes to create any type of text. Almost always, these activities require inscription equipment, either digital or physical: chisels, pencils, brushes, chalk, dyes, keyboards, touchscreens, etc.; each of these tools has unique affordances that influence writers' workflows.

Composition theorists have attacked the problem of accessing writers' thoughts in various ways. Flower and Hayes' essay, "A Cognitive Process Theory of Writing" sought to outline the writer's choice-making throughout the writing process, and how those choices constrained or influenced other choices down the line.
