City University of Hong Kong, or CityU for short, was founded in 1984, formerly known as the City Polytechnic of Hong Kong, and was upgraded to City University of Hong Kong in 1994. Each year, CityU offers about 130 high-quality undergraduate and research degree courses of different levels and majors to about 20000 students. The university now has schools of business, humanities and Social Sciences, science and engineering, creative media, energy and environment, and law. Apart from the school of energy and environment, the above-mentioned colleges are now open to the mainland. More than 48% of the nearly 600 outstanding professors from 30 countries, including fields and Wolff prize winners, 10 world-class academicians, 12 Yangtze scholars, 17 members of the international society of electrical and Electronic Engineering (IEEE), 6 Fulbright Fulbright senior scholars, and 5 Croucher Most of them hold doctorates from well-known overseas universities, and have long held full-time teaching and research positions in overseas universities. For six consecutive years (2004-2009), CityU has been selected as one of the 200 best universities in the world in the times higher education supplement. From 2007 to 2009, CityU was also selected as one of the 150 best universities in the world. In 2009, CityU jumped to 124. CityU ranked 18 in the list of Asian universities. CityU ranked in the international higher education information institution quacquarelli symbols In 2010, the world university ranked 129, the Asian University ranked 15, the social sciences of CityU ranked 105, and the humanities, engineering and information technology ranked 107.

Technology	Motion prediction is the process of determining the motion vector describing one image to another, and it is the key element of video compression. The proposed motion prediction technique reduces the prediction search time by establishing multiple search paths from the same starting point. It can find out the image points with the lowest comparison value on the search path. The image points are then transformed into new search points, from which a new search path is extended. Then, the new image point with the lowest comparison value is searched repeatedly until the comparison value of a point on the search path is higher than the starting point.
Advantages	Higher prediction quality Faster search Easy to implement on hardware, high data access efficiency
Possible applications	Video compression for digital encoding devices, such as digital video recorders, digital cameras and HD video systems
Category	Digital broadcasting and imaging technology
