In this paper, a new variational level set method is given to segment the left ventricle walls from cine cardiac magnetic resonance images. The variational formulation consists a quasi-local binary fitting term, an area term and a penalizing term. The quasi-local binary fitting term and the area term both drive the zero active contours toward the desired object boundaries. The quasi-local binary fitting...
It needs the environment to provide the essential physical conditions, the spiritual condition and the activity spots for a head teacher's work development. If there are not the conditions and the places to make the guarantee, a head teacher is unable to do the work normally. The construction and optimization of environment itself is one kind of education, a head teacher's working progress itself...
When ADAMS carries on the kinematics dynamic simulation analysis, the entity modelling, the increase restraint, the infliction driving influence, the movement simulation and so on, several steps should be carried on. If achieve a number of different actions step by step during simulation, sometimes need to select the appropriate function. This paper puts forward the research of using Max, min function...
