The University of Science and Technology of China is a national research university in Hefei, Anhui, China, under the direct leadership of the Chinese Academy of science . It is a member of the C9 League formed by nine top universities in China. Founded in Beijing by the CAS in September 1958, it was moved to Hefei in the beginning of 1970 during the Cultural Revolution.The inception and mission of USTC was in response to the urgent need for the national economy, defense construction, and education in science and technology. It has been featured by its competence on scientific and technological research and expanded into humanities and management with a strong scientific and engineering emphasis. USTC has 12 schools, 27 departments, the Special Class for the Gifted Young, the Experimental Class for the Teaching Reform, the Graduate Schools , the Software School, School of Network Education, and School of Continuing Education. In 2012 Institute of Advanced Technology of University of Science and Technology of China was founded. Wikipedia.

Embodiments of the present invention provide a method and a device for generating a morphing animation from multiple images, where the method includes: performing hue preprocessing on adjacent images among multiple images; determining the quantity of intermediate frames between the adjacent images according to a feature point differential of the adjacent images on which the hue preprocessing has been performed, generating, between the adjacent images through an image warping technology, intermediate frame images, the quantity of which is the same as that of the intermediate frames, insert the intermediate frame images between the adjacent images, and generate a morphing animation from the multiple images and the intermediate frame images that are inserted between all adjacent images among the multiple images. The morphing animation generated in the present invention is smooth and natural, thereby improving a morphing effect of the morphing animation.

Methods for rapidly determining earthquake parameters of an earthquake include inputting a seismogram of the earthquake, searching concurrently in pre-established historical seismogram database and theoretical seismogram database by use of an approximate nearest neighbor search method, to find a set of seismograms similar to the input seismogram according to a preset similarity condition, and determining from the set of similar seismograms one or more seismograms matched with the input seismogram, and determining the earthquake parameters from the matched seismograms. With the present invention, it is possible to search in millions of seismograms and determine parameters for an earthquake in a few second, and thus realize rapid and even real-time estimation of earthquake parameters.
