Constructor Detail

ImageSum

public ImageSum(int firstwidth,
                int secondwidth)

Constructs a new Image Sum

Parameters:

firstwidth - The width of the first input image

secondwidth - The width of the second input image

Method Detail

imageaddition

public int[] imageaddition(int[] src1_1d,
                           int[] src2_1d,
                           int width,
                           int height,
                           float oset,
                           float scale)

Applies the image sum operator on the specified image arrays, with the specified offset and scale value

Parameters:

src1_1d - The first source image as a pixel array

src2_1d - The second source image as a pixel array

width - width of the destination image in pixels

height - height of the destination image in pixels

oset - The offset value

scale - The scale value

Returns:

A pixel array containing the sum of the two input images

imageaddition

public int[] imageaddition(int[] src1_1d,
                           int width,
                           int height,
                           float oset,
                           float scale,
                           int constant)

Adds the specified constant value to the specified input image, also using offset and scale values

Parameters:

src1_1d - The input pixel array

width - width of the destination image in pixels

height - height of the destination image in pixels

oset - The offset value

scale - The scale value

constant - The constant value to be added to every pixel in the input array

Returns:

A pixel array with the constant value added to every pixel in the input array

imageaddition

public int[] imageaddition(int constant,
                           int width,
                           int height,
                           float oset,
                           float scale,
                           int[] src1_1d)

Adds every pixel in the input image to the specified constant value, also using offset and scale values

Parameters:

constant - The constant value to be added to every pixel in the input array

width - width of the destination image in pixels

height - height of the destination image in pixels

oset - The offset value

scale - The scale value

src1_1d - The input pixel array

Returns:

A pixel array with the sum of the constant value and every pixel in the input array
