TGVDenoise is a noise reduction process in PixInsight that you can use both with both linear and nonlinear images. When open TGVDenoise, the process looks like this: The default is the RGB/K mode, which...

Boosting Areas of Faint Signal Using Curves, StarNet and Other Processes
Sometimes your image includes some areas of faint signal like the nebula in the following image (Sh2-240): In this case, the nebula has a relatively low signal. If you begin your workflow by integrating...
Using BackgroundNeutralization To Neutralize The Background Of An Image
BackgroundNeutralization makes an adjustment to the entire image to make the background more neutral. Use BackgroundNeutralization when your image is in its linear state and after using a process like DynamicbackgroundExtraction to address gradients...
Using ColorCalibration To Calibrate An Image
The ColorCalibration process automatically calibrates the colors in your image based on a sample of white pixels and background pixels. You can provide the sample of white pixels or can allow ColorCalibration to acquire...
Using ExponentialTransformation To Stretch An Image
ExponentialTransformation (ET) is best used with images that have already been stretched using another process, so ET is best suited for non-inear images. ET enhances contrast in darker areas without stretching noisy areas, while...
Using EZ Soft Stretch To Stretch An Image
Update October, 2023: The EZ Processing Suite is no longer available in PixInsight Update October, 2023: The EZ Processing Suite is no longer available in PixInsight The EZ Processing Suite is a set of...
Using PixInshght’s ArcsinhStretch To Stretch An Image
ArcsinhStretch is a unique process in PixInsight because you can only use it with RGB data and it focuses on preserving color information. You have to do a couple of things before using ArcsinhStretch:...
Using MaskedStretch To Stretch An Image
MaskedStretch focuses on stretching mid tones and avoids saturating very bright regions. MaskedStretch works by progressively masking your image with each iteration of a stretch so that the mask becomes stronger as the number...
Using AdaptiveStretch To Stretch An Image
AdaptiveStretch that’s useful when you want to achieve a stretch in a short amount of time. If the amount of processing time is important to you, consider using the EZ Soft Stretch as well...
Using HistogramTransformation To Stretch An Image
HistogramTransformation is probably the most used tool to stretch an image into its nonlinear state because it is easy to use when used in conjunction with the ScreenTransferFunction (STF). You can use HistogramTransformation more...
