Object reconstruction from invariant features
S.X. Liao, Miroslaw Pawlak · 2002
In this research, we have studied the problem of object reconstruction from invariant features, which are calculated from discrete data within the circular domain. We give an accuracy analysis of the proposed estimate of f(x,y). It is found that there is an inherent limitation in the precision of the estimate due to the geometric nature of a circular domain. This is explained by relating the accuracy issue to the celebrated problem in the number theory called the lattice points of a circle.
