Hybrid image using image morphing

초록

Hybrid image refers to an image that is viewed in two different ways, depending on the distance of a viewer. This optical illusion comes from human perception of concentrating on the specific spatial frequency band information with regard to the observation distance, and it makes one excited and amazed. However, the existing hybrid image synthesis method has limited application to making diverse contents since two input images have to have similar shape and alignment for synthesis and sometimes the image is not easily perceived from certain distances. This paper suggests a new hybrid image synthesis method that improves the shortcomings of the existing method. By using the image morphing method, multiple morphed images are created, in which two images smoothly transform. Based on those, hybrid image is created. Our method can be used to create an excellent quality hybrid image without using images of similar shape or alignment, and the produced image is easily perceived at different viewing distances. In addition, we expect that these hybrid image contents, which are created in many different and easier ways, will be applied to diverse fields such as advertisement and exhibition. © 2015 ACM.
