According to the characters of abrupt change and gradual change,a twice difference based method and a window-difference maximum based method are proposed for abrupt change detection and gradual change detection separately.

Illustrated by some existing buildings,it is manifested that city architecture-the solidified music-shows the rhythm and cadence of continuity,gradual change,waving and overlapping,and therefore offers us the sense of artistic pleasure and enjoyment.

Although they lived in different ages and nations, Lenin and Deng Xiaoping held the identical idea about gradual change of economic system-the necessity of establishing economic system, how to start the gradual change and how to push the gradual change forward in a all-round way, etc.

Catastrophe and gradual changing are all consist in sports teaching system,gradual changing conduces catastrophe and catastrophe conduces creativity in sports teaching system.

Also proposed a new classifying method for dissolve transition,which was very short gradual transition,long gradual transition and short gradual transition.

The difference of similarities is used to enhance the abrupt transition features,and a Finite-State Automata is used to improve the robustness in detecting gradual transition.

The starting and ending frame of a gradual transition can also be located by further analysis of the slope curve.

Controllable morphing method using skeleton to extract features;

This paper presents an image morphing algorithm based on boundaries of region.

The paper summarizes the published researches from the aspects of morphing, expression mapping, statistical method, 2D meshes, facial color expression and performance-driven.
