imlincomb - Linear combination of images

Calling Sequence

imout = imlincomb(k1, im1, k2, im2, ..., kn, imn)

imout = imlincomb(k1, im1, k2, im2, ..., kn, imn, K)

imout = imlincomb(..., output_class)

Parameters

im1, im2, ..., imn: Input images with the same size and class.
k1, k2, ..., kn: Double scalars.
K: Offset, a double scalar.
output_class: A string which specifies the output image class. The value of output_class can be 'int8', 'uint8', 'int16', 'uint16', 'int32' or 'constant'.
imout: The linear combination of input images, which has the same size and class with input images or specified by output_class.

Description

imcomplement computes the linear combination of input images.

imout = k1*im1 + k2*im2 + ... + kn*imn [+K]

If imout 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 = uint8([0, 50, 100; 150, 200, 250]);
    im2 = uint8([1, 52, 103; 154, 205, 255]);
    imlincomb( 0.43, im1, 0.7, im2)
    imlincomb( 0.43, im1, 0.7, im2, 4)
    imlincomb( 0.43, im1, 0.7, im2, 4, 'int16')
    imlincomb( 0.43, im1, 0.7, im2, 4, 'constant')
