Abstract:RSKNN is an improved algorithm of KNN with better classification performance. The RSKNN algorithm is based on the theory of the variable precision rough set. The algorithm guarantees under the premise of a certain classification accuracy, effectively reduces the computation burden of the classified samples, and improves the computation efficiency and precision of classification. But the degree of dependence on attributes is very high, which can make RSKNN algorithm affected by a certain degree of precision in classification.

Abstract:The traditional ant colony clustering algorithm treats all features of data set equally. But in practice, the contribution rate of attributes is different from each other. Therefore, giving all features the same weight will eventually affect the quality of clustering. To overcome the defect, the method of principal components analysis is introduced into the ant colony clustering algorithm to calculate the contribution rates of attributes and to construct the weights of attributes. On this basis, combined with a new initialization strategy, an improved ant colony algorithm with weighted attributes is proposed in this paper. The experiments on several UCI data sets validated the effectiveness of the proposed algorithm. The results show that reasonable weight distribution can effectively improve the quality of clustering.

Abstract:The regional copy-move tampering for a digital image is one of the most common forgery methods. This paper proposes a detection algorithm based on wavelet moment to detect the location of image copy-move tampering. Firstly, we tentatively figure out the suspicious tampered areas in an image by the active contour model based on variational level sets. Secondly, the wavelet moment algorithm is employed to extract wavelet moment features from all suspicious areas. Finally, the real tampered areas are located by using cosine correlation measure to judge the similarity of those suspicious tampered areas. The experiment demonstrates the effectiveness of above mentioned algorithm and its good robustness to the operations of translation, rotation and scale for foreground tampered areas.

Abstract:Digital image compression is very important in digital communication and storage. It is an active field in information technology. This paper uses the wavelet transform, through the quantization and entropy coding, to realize the image compression. The compression performance is analyzed in terms of compression threshold and quantization order. When the threshold increases, the impression ratio also increases, but the restored image will have worse quality. On the other hand, when the quantization order increases, the restored image will have better quality, but the compression ratio will decrease.

Abstract:Fractal image coding is an novel and an developed potential image compression technique based on the local self-similarities within real world images. However, the baseline fractal image coding is time consuming due to the best matching search between range blocks and numerous domain blocks. In order to reduce encoding times, the paper proposed an improved scheme for fractal image coding based on pixel sampling. The improved scheme not only does not need any complex theoretical analysis, but also does not need to change the existing fractal decoding procedure; thus it can bring in other fast fractal image encoding algorithms in a straightforward manner. Computer simulations on a set of standard images show that match searching time can be reduced substantially and the subject image quality remain unchanged basically, while the PSNR being decreased slightly.
