Competing hypotheses about evolutionary origins of flight are the 'fundamental wing-stroke' and 'directed aerial descent' hypotheses. Support for the fundamental wing-stroke hypothesis is that extant birds use flapping of their wings to climb even before they are able to fly; there are no reported examples of incrementally increasing use of wing movements in gliding transitioning to flapping. A...

Morphing is a process of shape transformation between two objects. This paper focuses on morphing of simple polygons. In general, the key part of most morphing methods is to find correspondence between vertices of both objects. We present a new algorithm trying to avoid this step. Using an idea of intersection of two polygons (called core) the problem of morphing polygons is decomposed to sever...

The Beier-Neely feature-based image-morphing method is studied. Then, software implementing the Beier-Neely image-morphing method, designed and developed by the author, is presented. The software consists of three programs. The first program is a graphical user interface (GUI) used to manually select feature line segments. The second program is a morphing program that generates a morphing image...

This paper describes algorithms that can musically augment the realtime performance of electronic dance music by generating new musical material by morphing. Note sequence morphing involves the algorithmic generation of music that smoothly transitions between two existing musical segments. The potential of musical morphing in electronic dance music is outlined and previous research is summarise...

Morphing is a well known technique to generate smooth transitions between two objects. We propose a more general understanding of morphing: First, we use morphing to describe objects as a composite of other objects. Second, we allow this description to incorporate more than two base objects. Given this concept a set of objects produced by morphing among multiple objects forms a mathematical spa...

Nowadays, face morphing is used in various fields of works such as computer animations, games and movies. Face morphing is an effect that shows a transition from one face image to another face image smoothly. Research on face morphing is as vast as the many interests and needs that can be found in the general public, television or film production. In this paper, we thus review the different mor...

Map morphing is an interactive visualization technique that provides a user-controlled, animated translation from one map to another. Traditionally, overlay mechanisms are used to present layers of information over a single projection. Map morphing provides a way to relate maps with significant spatial and schematic differences. This paper presents the morphing technique and the results of a co...

A visual illusion is presented in which the perceived changes in a morphing sequence depend on eye movements. The phenomenon is illustrated using face morphs: when tracking a moving dot superimposed on a face morphing sequence, the changes in the morphing sequence seem rather small, but when the dot stops moving, the perceived extent of morphing suddenly becomes much larger. We explore this phe...

A surface light field is a function that gives the colors of each object point viewed from different directions. Object representation with a surface light field provides a nice structure for 3D photography. This paper presents a feature-based morphing technique for two objects equipped with surface light fields. The technique consists of geometry morphing and in-between light field mapping. Ge...
