Animating Chinese Paintings through Stroke-Based Decomposition1

This paper proposes a technique to animate a “Chinese style” painting given its image. We first extract descriptions of the brush strokes that hypothetically produced it. The key to the extraction process is the use of a brush stroke library, which is obtained by digitizing single brush strokes drawn by an experienced artist. The steps in our extraction technique are to first segment the input ...

Through the Looking Glass

In 1986, when I first started to think about the invariant theory of finite groups, there existed only one superb reference, the article by R.P. Stanley[1]. Since that time, there has been an explosion of interest, with many books and articles published, and conferences held. For example, there are two books by Bernd Sturmfels[2],[3], David Benson’s book[4] Polynomial Invariants of Finite Group...

Through the Looking Glass

It is frequently possible to produce new Calabi–Yau threefolds from old ones by a process of allowing the complex structure to degenerate to a singular one, and then performing a resolution of singularities. (Some care is needed to ensure that the Calabi– Yau condition be preserved.) There has been speculation that all Calabi–Yau threefolds could be linked in this way, and considerable evidence...

Providing the foundation for the entire hematopoietic system throughout the life of an organism, limited numbers of hematopoietic stem cells (HSCs) must remain largely quiescent, only entering the cell cycle when required to provide differentiated progeny. Indeed, the quiescent state of the cell cycle is believed to be indispensible for the maintenance of HSCs. HSCs must balance their entry int...
