Abstract
In this paper, we present a nonlocal structure tensor for feature description and apply it to the pixel level image fusion within the wavelet framework. Local geometric shape information in wavelet coefficients can be extracted and recognized by structure tensor. The structure tensor element is processed by use of the nonlocal means filter before calculating its eigen-values. With the eigen-values of two source data, an adaptive weight function is employed to reconstruct new detail coefficients of the fused image. Experimental results show the performance of the proposed scheme.
