pmergeimages

Merges 4 images into one image.

Synopsis

Description

pmergeimages merges the four input images im_in1, im_in2, im_in3, im_in4 to build the output image im_out. They are merged as follows:

    [im_in1][im_in2]
    [im_in3][im_in4]

The input images are supposed to be of the same type. They size must be compatible:

im_in1 width = im_in3 width;
im_in2 width = im_in4 width;
im_in1 height = im_in2 height;
im_in3 height = im_in4 height;

The size of the output image is (im_in1 + im_in2) width and (im_in1 + im_in3) height.

Inputs

im_in1, im_in2, im_in3, im_in4: 2D images of the same type and with compatible size.

Outputs

im_out: a 2D image.

Result

Returns SUCCESS or FAILURE.

Examples

Builds a synthetic image to illustrate the Gibbs phenomenon in wavelets analysis.
