Often when working with 2D gels, the resulting images have all kinds of
artefacts in them. These gels are often regarded as 'bad' and while it
may be true that they can be better, in practice the necessary
information might still be present. By using
specific denoising techniques it is possible to retrieve this
information, thereby removing many of the unwanted effects. The left
picture shows a typical gel which is troubled with 'washing' effects.
The right one shows the denoised gel.
