A New Scheme for Affine Invariant-Descriptor and Affine Transformation Parameter Estimation Based on ICA
Liming Zhang · Dianzi xuebao · 2004
This paper proposes a new scheme based on Independent Component Analysis (ICA) for object recognition with affine transformation and for affine parameter estimation.For different skewed shapes of recognized object,an invariant descriptor can be extracted by ICA,so it can solve some deformed object recognition problems.This method also can be used to estimate the affine motion between two frames,which is important in high compression rate coding such as MPEG4 or MPEG7 standard.Experimental results show that the proposed method has a better performance than other traditional methods in pattern recognition and affine motion estimation.
