Analysis and Application of Image SVD as Filter Evaluation Standard

The effect of the image filter using SVD directly is strongly restricted by image interclass orientation and noise characteristic. By simulation and analysis, this paper present that not only the singular values but also the singular vectors are sensitive to above mentioned factors. And a method using the sensitivity is proposed to evaluate and select appropriate filtering methods quantitatively. The comparison is basing on the singular values of various filters outputs. The following simulation results show that the method can reflect the filtering effect of visual experience; it could be used for a large number of real-time image filtering and video filtering.
