This paper proposed a sub-pixel image correlation algorithm that can get more Precise result
its principle is apply the distribute of relativity peak to get weighted multi-pixel comprehensive of location. Image correlation be as to calculates the greyscale relativity of image template and matching image
the relativity of correspond location where match best with template will be most high
and in its neighbour range
the relativity will be still keep high too. We used these pixel in this local area of calculated match point to get sub-pixel accuracy
the relativity of every pixel be used as its weight for participate the sub-pixel calculation. The sub-pixel location is more accuracy than the integer one
we applied this method to perform background compensation in processing the target detecting for video image sequence. At the end of this paper
some experiment data be proposed
it proved this sub-pixel image correlation can obtain better result. 2011 SPIE.

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.
