The phase of optical wave can be recovered by the intensity transport equation under the paraxial approximation For the optical system with diffraction limit, it is difficult to get the boundary radical slope of phase and sample in the circular domain boundary when using the intensity transport equation to recover the phase, consequently, we reviewed an algorithm mentioned in the reference ［4］, namely, the equation, computation domain and boundary condition are changed, then the phase is reconstructed by the multigrid method and corrected at last Moreover, the experiment system is set to testify the algorithm, and the recovered phase from the intensity data detected by CCD is compared with the result from phase retrieval algorithm, it is found that the phase reconstruction error can reach 017 λ in the case of non-uniform intensity distribution, as a result, the method is suitable for the phase recovery with low wavefront sensing accuracy.

It's obvious that semantic retrieval is more reasonable than retrieval based on low features. So we need to study image retrieval based on region segmentation, image hierarchical classification and image semantic label standard.

In this paper, three methods for color image retrieval have been presented: hypercomplex SVD image retrieval, combination of hypercomplex convolution filter and hypercomplex SVD image retrieval and hypercomplex matrix correlation image retrieval. We made comparison among these hypercomplex-methods, and compared them with the traditional image retrieval methods. Experiment results showed that the hypercomplex-methods we presented in this paper could well conquer the problems existed in traditional image retrieval methods, and their retrieval results are much better. Meanwhile, this paper presented a new color image quality assessment based on hypercomplex SVD. It is a novel color image quality assessment that can be used as a graphical or a scalar measure to predict the distortion introduced by a wide range of noise sources. It reliably measures the distortion not only within a distortion type at different distortion levels, but also across different distortion types.

The main works of this paper include four points as follows:(1) Patent retrieval domain ontology is designed through analyzing the common concepts in searching patent information. And the international patent classification table is expressed using ontology;(2) Design users'interests model from the information actively provided by users and passively provided by system based on users'requirements and historical searching record;(3) Design and implement three patent retrieval modes: quick search, table search, and advance search to meet various users'demands. And combine ontology, user's interest model and the inputed retrieval condition when users search for patent informations. This realizes individualized retrieval which meets the demands of users;(4) When users's search term is inaccurate, the precision will drop markedly and users will receive many disrelated informations.
