Summary
Vignetting Correction
is the process of
Adjusting an image
to compensate for the gradual
Decrease in brightness
or saturation towards the periphery compared to the
Image center
, which is often caused by
Optical limitations of lenses
. This correction is crucial for ensuring
Uniform exposure
across the
Entire image
, thereby enhancing the
Overall Quality
and
Accuracy of visual data
.
