Multiscale Image Blending
Multiscale image blending can be done by combining the result of blending at different levels of an image pyramid. A multiscale representation of an image is generated using ImagePyramid.
In this example, the portraits of Werner Heisenberg and Erwin Schrödinger, the founders of matrix and wave mechanics, are blended.
Split and merge the two images without blending.
One can split and merge the images at all scales using image pyramids.
