In original ASM scheme, the model of object′s gray-level variations is based on the assumption of one-dimensional sampling and searching method. In this work a new way to model the gray-level appearance of the objects is explored, using a two-dimensional sampling and searching technique in a rectangular area around each landmark of object shape. The ASM based on this improvement is compared with the original ASM on an identical medical image set for task of spine localization. Experiments demonstrate that the method produces significantly fast, effective, accurate results for spine localization in medical images.展开更多

Especially in the last decade, we seize the sustained, rapid and healthy development of the favorable opportunity of the construction of social security system; we have made unremitting efforts and achieved important progress. After years of exploration and practice, we have a clear basic principles of the social security system and the overall objectives and major tasks, we also established social pooling and individual accounts of the basic old-age insurance, basic medical insurance system, covering pension, medical, unemployment, work injury and maternity insurance, the urban minimum living security system and the framework of the social security system basically forms. The coverage of social insurance continuously expands social security funds which are through nmltiple channels to raise the initial formation mechanism forms, the level of protection continuously improves, and management and service system also gradually improves. The social security system' s reform and development plays a very important role in ensuring the basic livelihood of the people, the state-owned enterprise reform, and the smooth progress of economic restructuring.展开更多
