Image Arithmetic


The Image Arithmetic command performs various arithmetic operations between an image or image set and a second, or "operand" image. The first image must be displayed but the operand image may be displayed or in a file.

Mira provides the following image arithmetic operations between pairs of images.

Operations Between Pairs of Images

Add

Adds the pixel values of the images.

Subtract

Subtracts the second image from the first one.

Multiply

Multiples the pixel values of the images.

Divide

Divides the second image into the first one. The result is set to Error Value if the pixel in the second image has a value of 0.0.

Blend

Blends the two images by interpolating their pixel values at each point.

Remainder

Computes the remainder of dividing the second image into the first one. The result is set to Error Value if the pixel in the second image has a value of 0.0.
