As a suitable tool for analyzing concept interconnection formally, the theory of Formal Concept Analysis (FCA) is applied. FCA deals with formal mathematical tools and techniques to develop and analyze relationship between concepts and to develop concept structures, and concepts are important building blocks in the concept-interconnection. This paper mainly discusses how FCA can be used to support concept-interconnection analysis from an application point of view. In order to introduce our idea, two kinds of concept-interconnection and interconnection measure in detail are discussed. One is based on Concept-Backbone and the other is based on the attributes. It is seen that FCA can support the building of concept-interconnection as a learning technique, but the established concept-interconnection also can be analyzed by using techniques of FCA.

In this paper, a new image classification method is developed. This approach applies graph decomposition and probabilistic neural networks (PNN) to the task of supervised image classification. We use relational graphs to represent image. These graphs are constructed from the feature points of images. Spectra of these graphs are obtained as feature vectors for classification. PNN is adopted to classify image according to the feature vectors. Experimental results show that this method can achieve best result of images classification.

An efficient robust watermarking scheme for digital images is presented, based on the discrete Gabor transforms (DGT), The watermark in digital images is hidden by changing their DGT coefficients to represent special low frequencies. In the proposed watermark-checking algorithm, the geometric transforms and corresponding matching method are applied for geometric transformed images in order to recover them for watermark-checking. The proposed scheme was tested by StirMark 4.0, a well-known software for testing watermarking schemes, and it performed successfully in almost all testing cases with high robustness and efficiency.

Two algorithms for the phase retrieval of hard X-ray in-line phase contrast imaging are presented. One is referred to as Iterative Angular Spectrum Algorithm (IASA) and the other is a hybrid algorithm that combines IASA with TIE (transport of intensity equation). The calculations of the algorithms are based on free space propagation of the angular spectrum. The new approaches are demonstrated with numerical simulations. Comparisons with other phase retrieval algorithms are also performed. It is shown that the phase retrieval method combining the IASA and TIE is a promising technique for the application of hard X-ray phase contrast imaging.
