Combine Image Set

Combines more images into a single image. The images must be opened as an image set in a single window.

Combine Files

Combines images from files to make a single image. This command works only with FITS format files.

Normalize Image

Normalizes 1 or more images to a common statistical value evaluated inside a rectangular region. The reference value may be determined from another image or set to a specified value.

Image Arithmetic

Applies various arithmetic operations between two images.

Value Arithmetic

Applies various arithmetic operations between an image and a constant value.

Arithmetic Operations

Applies various mathematical operations that do not depend upon anything but the image itself, such as square root or logarithm.

Correct Background

Fits a surface to an image and subtracts or divides it into the image or creates a new image from the surface. This is often used for flattening the image background.

Create Synthetic Image

Creates synthetic images containing all sources of random noise, Optionally, stars may be added for use in evaluating image processing techniques and algorithms, as well as other purposes.

Change Pixel Type

Converts the pixel format of an image from one type to another (e.g., 16 bit integer to 32 bit real).

Extract Byte Plane

Creates a new image from a specified byte index of a luminance image.

Region Statistics

Used to configure the statistical estimator used to assign a value to an image region. This tool is used by various math commands.
