The SUBTRACT arithmetic operator subtract an image from .

The formula is:

Remarks:

• Overflows may occur.

• The result of a subtraction between two binary images is a short integer image; this operation is not equivalent to a logical difference.

• Be careful with negative values and the way they are visualized.

The MULTIPLY arithmetic operator multiplies an image by another .

The formula is:

Remarks:

• Overflows may occur.

• Be careful with negative values and the way they are visualized.

• Multiplying a binary image by a grayscale image is equivalent to a masking operation.

The DIVIDE arithmetic operator divides an image by another .

The formula is:

Remarks:

• Overflows may occur.

• Be careful with negative values and the way they are visualized.

• If then

The MINIMUM arithmetic operator computes the minimum value between two images and .

The formula is:

For binary images, the MINIMUM operator is equivalent to a logical AND.

The MAXIMUM arithmetic operator computes the maximum value between two images and .

The formula is:

For binary images, the MAXIMUM operator is equivalent to a logical OR.
