Tools
-
AdaptiveStretch
Adaptive nonlinear intensity transformation based on existing pixel-to-pixel relations.
-
Annotation
An interactive text rendering procedure implemented as a dynamic process.
-
AssistedColorCalibration
Performs a manual color calibration procedure with previewing of background correction, histogram stretching and color saturation transformations.
-
AutoHistogram
Automatic histogram transformation based on statistical image properties.
-
B3Estimator
Using the laws of blackbody radiation, generates a synthetic image as an estimate of flux at the specified effective output wavelength or frequency, and/or a thermal map as an estimate of temperature.
-
BackgroundNeutralization
Neutralizes the sky background of a color deep-sky image.
-
ChannelCombination
Combines several pixel channels or color space components into a RGB color image.
-
ChannelExtraction
Extracts one or more pixel channels or color space components from a RGB color image.
-
ColorCalibration
Calibrates the color of a linear deep-sky image based on documentary criteria.
-
Crop
Adds or removes image margins.
-
CurvesTransformation
Implements pixel intensity transformations by interpolation of functions defined through arbitrary user-definable points.
-
Debayer
Converts a Color Filter Array (CFA) image into a regular RGB color image.
-
DefectMap
Replaces pixel values using a defect map image.
-
DynamicCrop
Interactive tool to crop, rotate and scale images.
-
DynamicPSF
A dynamic tool for interactive PSF fitting.
-
FastRotation
Rotates images by integer multiples of 90 degrees, or mirrors images horizontally or vertically.
-
FluxCalibration
Calibrates an image by applying a conversion factor between instrumental counts and physical energy flux.
-
GradientHDRComposition
Implements a High Dynamic Range (HDR) composition of images with different exposures. Uses a gradient domain method.
-
GradientHDRCompression
Implements a method that enhances fine contrast details. It can be applied to any image with large contrast differences, including HDR images.
-
GradientMergeMosaic
Implements gradient domain mosaic creation by merging several registered images into one image without visible borders and seams.
-
HistogramTransformation
Implements pixel intensity transformations defined by histogram clipping, midtones balance and dynamic range expansion points.
-
ImageIntegration
Combines images pixel-by-pixel for signal-to-noise ratio improvement and rejection of spurious image structures.
-
IntegerResample
Image rescaling by integer factors.
-
LocalHistogramEqualization
Implements local equalization of the histogram. Can be used to enhance local contrast and visibility of structures in the image.
-
RangeSelection
Generates a mask defined by a range of selected pixel values with optional fuzziness, smoothness, mask inversion and lightness/RGBK source components.
-
Resample
Changes the dimensions of an image by interpolation of new pixel values from original pixel data.
-
Rotation
Rotates images by arbitrary angles.
-
ScreenTransferFunction
Defines a set of histogram transformations applied to the screen rendition of an image, without modifying its pixel data.
-
StarAlignment
Automatic image registration and mosaic generation using stars as alignment references.
