12.5 Image Corrections in
Fluorescence Microscopy
In modern biological microscopy, fluorescence imaging is used to record and
quantify location, functional status, and abundance of a tagged target molecule.
This requires the application of image correction techniques and calibration
methods for both image visualization and quantitative analysis. Digital image
processing algorithms for correction and calibration strategies are discussed in
the following sections.
12.5.1 Background Shading Correction
The process of eliminating nonuniformity of image background intensity by
application of image processing to facilitate visualization and segmentation or
to obtain accurate quantitative intensity measurements is known as background
correction, background flattening, ...
