What is deconvolution in imaging?
Deconvolution is a computationally intensive image processing technique that is being increasingly utilized for improving the contrast and resolution of digital images captured in the microscope. A series of images are recorded of the sample, each shifted slightly from one another along the z-axis.
What does deconvolution do Pixinsight?
Deconvolution is a mathematical operation that can be applied to in effect undo some of this distortion, by first modelling it with some stars in the image. This is done very early-on in a post-processing workflow, in an image’s linear state.

How are deconvolution algorithms used in optical microscopy?
The most commonly utilized algorithms for deconvolution in optical microscopy can be divided into two classes: deblurring and image restoration. Deblurring algorithms are fundamentally two-dimensional, because they apply an operation plane-by-plane to each two-dimensional plane of a three-dimensional image stack.
Can a deconvolution of an image restore the object?
If the imaging system is modeled as a convolution of the object with the point spread function, then a deconvolution of the raw image should restore the object. However, the object cannot be restored perfectly because of the fundamental limitations inherent in the imaging system and the image-formation model.
Which is the best subject for deconvolution analysis?
Among the most suitable subjects for improvement by deconvolution are three-dimensional montages constructed from a series of optical sections. The basic concepts surrounding acquisition of z-series images for deconvolution analysis are presented with a schematic diagram in Figure 1.
