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.
Open this dialog from the Process > Math menu.
Mira provides the following arithmetic operations on a single image.
Mathematical Operations on a Single Image
|
Change Sign |
Changes the sign of the pixel values. |
|
Swap Byte Order |
Swaps (reverses) the byte order of pixel values. |
|
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 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 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 Value if the pixel has a value < 0.0. |
