Purpose

This module performs arithmetic operations on two images.

The output is the processed image according to the selected function and constant.

Usage

Select the arithmetic operation you want to apply to the two input images. Some operations (see below) require the specification of a further constant.

Tips

The example network demonstrates how two images can be added by the Arithmetic2 operator.

Function

name: function, type: Enum, default: Add, deprecated name: Function

Defines the operation which is applied to the two input images.

Values:

Title	Name	Deprecated Name	Description
Add	Add	Add (IMG1+IMG2)	The input image 1 increased by input image 2 is passed to the output.
Multiply	Multiply	Multiply (IMG1*IMG2)	The input image 1 multiplied by input image 2 is passed to the output.
Subtract	Subtract	Subtract (IMG1-IMG2)	The input image 1 decreased by input image 2 is passed to the output.
Divide	Divide	Divide (IMG1/IMG2)	The input image 1 divided by input image 2 is passed to the output.
Max	Max	Max (IMG1, IMG2)	The maximum value of input images 1 and 2 is passed to the output.
Min	Min	Min (IMG1, IMG2)	The minimum value of input images 1 and 2 is passed to the output.
Abs Max	AbsMax		The value of input images 1 and 2, which is the maximum absolute value, is passed to the output.
Abs Min	AbsMin		The value of input images 1 and 2, which is the minimum absolute value, is passed to the output.
Or	Or	OR (IMG1 or IMG2)	Apply a logical OR operation on the images. The OR operation is performed bitwise.
And	And	AND (IMG1 and IMG2)	Apply a logical AND operation on the images. The AND operation is performed bitwise.
Xor	Xor	XOR (IMG1 xor IMG2)	Apply a logical XOR operation on the images. The XOR operation is performed bitwise.
Difference	Difference	Difference (|IMG1-IMG2|)
Mask	Mask	MaskIn (IMG2 ? C : IMG1)	The ouput image data will be copied from image 1 where image 2 is zero. Where image 2 is non-zero, the value Constant will be written. This can be used to perform a "mask in" operation writing a different value than the one in the original mask and can be useful when both images have different data types.
Equal	Equal	EQ (i1 == i2 ? C : 0)	The output image will have the value Constant, if image 1 equals image 2. Otherwise it will be zero.
Not Equal	NotEqual		The output image will have the value Constant, if image 1 not equals image 2. Otherwise it will be zero.
Equal Mask	EqualMask		The output image will have the value Constant, if image 1 equals image 2 and both images are not zero. Otherwise it will be zero.
Not Equal Mask	NotEqualMask		The output image will have the value Constant, if image 1 not equals image 2 and both images are not zero. Otherwise it will be zero.

Constant

name: constant, type: Double, default: 0, deprecated name: C

Sets a constant value required for some arithmetic operations (see Function).

Auto Replicate

name: autoReplicate, type: Bool, default: FALSE
