Many image watermarking methods have been proposed over the last decade; however, most of them only focus single or two purposes, verification of copyright and integrity. This paper proposed a multipurpose watermarking method based on blind vector quantization (BVQ) and there are three purposes, copyright protection, integrity verification, and distinguish between malicious and non-malicious manipulations,...
The product identity is an important topic in modern design. However very little research on the cognition of product identity based on consumers' image and design model has been reported. This article has proposed the cognition concept of the product identity image, and analyzed the main method based on the image cognition. According to the features of the product identity, this study has employed...
In this paper, we propose a vector quantization (VQ) -based information hiding scheme that cluster the VQ codewords according the codewordspsila relation on Voronoi Diagram (VD). The clustering method is fast and easy to implement when projecting the codewords into VD space. The hiding capacities can be adaptive adjusted just modifying the threshold value which didnpsilat need reorganizing the codebook...
Quantifying the economic benefit of a transmission upgrade is a critical step in economic transmission planning. Because of the complexity of the energy market, and the difficulties of estimating the FTR revenue and marginal loss credit in the planning horizon year, it is not easy to find an economic index which can accurately capture the economic benefit for all kinds of entities. This paper shows...
