Although animated meshes are frequently used in numerous domains
only few works have been proposed until now for simplifying such data. In this paper
we propose a new method for generating progressive animated models based on local feature analysis and deformation area preservation. We propose the use of solid angle and height value for a non-hyperbolic vertex to define the local feature parameter. This local factor is embedded to the vertex quadric error matrix when calculating the edge collapse cost. In order to preserve the areas with large deformation
we add deformation degree weight to the aggregated quadric errors when computing the unified edge contraction sequence. Finally
a mesh optimization process is proposed to further reduce the geometric distortion for each frame. Our approach is fast
easy to implement
and as a result good quality dynamic approximations with well-preserved fine details can be generated at any given frame. 2010 IEEE.

Active pixel sensor (APS) star tracker becomes an investigated hotspot because of its technical advantages. And centroid algorithm is a subpixel method proper to star position calculation because of its high accuracy and simplicity. When centroid algorithm is applied on APS star tracker
APS pixel geometrical characteristics might effect on star image position accuracy. Because the amplifier circuit and other function circuits inter pixel of APS take up some pixel area
the Fill Factor is less than 100%. Moreover
the active sensitive area has a certain geometrical shape
such as square
rectangle and L shape. The Fill Factor of pixel influences on star image subdivided locating accuracy when using centioid algorithm. In this paper
we have analyzed all pixel geometrical characteristics influence on the star position accuracy. From simulation experiments
we can conclude that Fill factor and pixel geometric shape influence on star position accuracy. The star locating error increased when Fill Factor decreased
and different geometrical shape of active sensitive area of pixel can make different influence on star location accuracy
the symmetrical sensitive area in x or y axis have symmetrical location error in the same axis.
