| Description |
Simple function to write one image matrix over another using a given "origin" pixel and an offset vector. If the pasted image extends beyond the bounds of the base image, the base image is padded using the built-in function PADARRAY.
I = imagepatch(image1,image2,...
[originx originy],[offsetx offsety]) returns a new image containing image1 overwritten by image 2 at the location
specified by the offset and origin coordinates.
[I origin] = imagepatch(im1,im2,...
[origin_x origin_y],[offset_x offset_y])
returns a new image, I, and a vector, origin, containing the pixel coordinates corresponding to the origin in the new image.
I = imagepatch(im1,im2,...
[origin_x origin_y],...
[offset_x offset_y],padval)
returns a new image, where padval specifies the padding value used by
PADARRAY if it is necessary to expand im1 to accomodate im2 at the offset
coordinates.
Example:
moon = imread('moon.tif');
pout = imread('pout.tif');
%origin at center
origin = round(flipdim(...
size(moon),2)./2);
offset = [200 250];
imshow(...
imagepatch(moon,pout,origin,offset)); |
