MULTIPLY_CVIP

multiply_cvip() - Multiply two images or multiply an image by aconstant .

Contents

SYNTAX

Z = multiply_cvip(X,Y)

Input Parameters include :

Output parameter include :

DESCRIPTION

This function multiplies each element in array X by the corresponding element in array Y and returns the result of multiplication in the corresponding element of the output array Z.If one of the input parameter is constant,multiply the constant value to each element in array of another input image.

Z is an array of type double.

If X and Y are numeric arrays of the different size, smaller size arrays are zero padded and multiplication is performed.

To view the 8-bit image of type double, divide by 255.

To view the 16-bit image of type double, divide by 65535.

EXAMPLE

% Read Image

 X1 = imread('Cam.bmp');

 Y1 = imread('Car.bmp');

 Y2 = 50;

% Call function

 S1 = multiply_cvip(X1,Y1);

 S2 = multiply_cvip(X1,Y2);

% Display Input Image

 figure;imshow(X1);

 figure;imshow(Y1);

% Display Output Image

 figure;imshow(remap_cvip(S1));title('Output image 1');

 figure;imshow(remap_cvip(S2));title('Output image 2');
