imadd

Add two images or add a constant to an image

Syntax

imout = imadd(im1, im2)

Parameters

im1 :

Input image.

im2 :

Input image with the same size and same class with im1 , or a double scalar.

imout :

The sum of im1 and im2 .

Description

If im1 and im2 are images with the same size and same class, imadd adds each element in im1 to the corresponding one in im2. If im2 is a double scalar, the element in imout is the sum of the corresponding one in im1 with the double scalar. imout has the same size and class with im1.

If im1 is an integer matrix, the elements in the output matrix imout that exceed the range of the integer type will be truncated.

Supported classes: INT8, UINT8, INT16, UINT16, INT32, DOUBLE.

Examples

im1 = imread(fullpath(getIPCVpath() + "/images/baboon.png"));
im2 = imread(fullpath(getIPCVpath() + "/images/peppers.png"));
ims1 = imadd(im1, im2);
ims2 = imadd(im1, 50);
imshow(ims1);
scf(); imshow(ims2);
