Arithmetic Operations
The Arithmetic Operations command performs various unary arithmetic operations on an image or image set. These are called "unary operations" because they involve only one image.
The Arithmetic Operations command opens
from the Image Window > Process
> Math menu and 
button
on the Main Toolbar. The "immediate"
form, shown first, opens when an image or image set is displayed in
the top-most window. The general form can be used to select source
images from folders, windows, or by matching templates.

Operation |
Select the operation to perform from the following options: Change Sign Creates an image with negative values of the original pixels. Swap Byte Order Swaps the order of bytes in the image pixels. Exponential Raises e to the power of the pixel values. Lob Base e Computes the base e log of the pixel values. The result is set to Error replacement value if the pixel has a value of 0.0. Log Base 10 Computes the base 10 log of the pixel values. The result is set to Error replacement value if the pixel has a value of 0.0. Absolute Value Computes the absolute value of the pixel values. Reciprocal Computes the reciprocal of the pixel values by dividing them into 1.0. Square Root Computes the square root of the pixel values. The result is set to Error replacement value if the pixel has a value < 0.0. |
