Class ImageMath

java.lang.Object
imagingbook.common.image.ImageMath
public abstract class ImageMath extends Object
This class defines static methods for non-destructive, arithmetic operations on ImageJ's ImageProcessor objects. Unlike the built-in ImageProcessor methods, the methods below always return new images (of the same type) and keep the original images unmodified.
Version:

    Description
    static <T extends ImageProcessor>
    T
    abs(T ip)
    Calculates the absolute pixel values of the specified image and returns a new image of the same type.
    static <T extends ImageProcessor>
    T
    add(T ip1, T ip2)
    Adds the pixel values of the specified images and returns a new image of the same type as the first image.
    static <T extends ImageProcessor>
    T
    mult(T ip1, T ip2)
    Multiplies the pixel values of the specified images and returns a new image of the same type as the first image.
    static <T extends ImageProcessor>
    T
    sqr(T ip)
    Calculates the squared pixel values of the specified image and returns a new image of the same type.
    static <T extends ImageProcessor>
    T
    sqrt(T ip)
    Calculates the square root of the pixel values of the specified image and returns a new image of the same type.
