Image math

Description

Applies a mathematical operation to all pixels of the input image stack. Operations that can be performed are: Absolute, Add, Divide, Multiply, Square, Squareroot, Subtract

Parameters

Input image (default = "") Image from workspace to apply calculation to. This image can be of any bit depth.

Apply to input image (default = "true") When selected, the post-operation image will overwrite the input image in the workspace. Otherwise, the image will be saved to the workspace with the name specified by the "Output image" parameter.

Output image (default = "") If "Apply to input image" is not selected, the post-operation image will be saved to the workspace with this name.

Calculation (default = "Add") Controls the mathematical operation being applied to all pixels of this image. Choices are: Absolute, Add, Divide, Multiply, Square, Squareroot, Subtract

Value source (default = "Fixed value") For calculations that require a specific value (i.e. addition, subtraction, etc.) this parameter controls how the value is defined:
- "Fixed value" A fixed value is specified using the "Value" parameter. This value is the same for all images processed by this module..
- "Measurement value" The value is taken from a measurement associated with the input image. Values obtained in this way can be different from image to image.

Measurement (default = "") If "Value source" is set to "Measurement value", this is the measurement associated with the input image that will be used in the calculation.

Value (default = "1.0") If "Value source" is set to "Fixed value", this is the value that will be used in the calculation.
