In this paper, a novel image fusion algorithm based on orientation information measure and lifting stationary wavelet transform (LSWT) is proposed, aiming at solving the fusion problem of multifocus images. In order to select the coefficients of the fused image properly, the selection principles for different subbands are discussed, respectively. For(More)
In this paper, a new multifocus image fusion scheme based on the technique of focused pixels detection is proposed. First, a new improved multiscale Top-Hat (MTH) transform, which is more effective than the traditional Top-Hat transform in extracting focus information, is introduced and utilized to detect the pixels of the focused regions. Second, the(More)
In this paper, a new multifocus image fusion scheme based on fractional differential and NSCT is proposed. Firstly, in virtue of the properties of fractional differential, a novel focus measure in nonsubsampled contourlet transform (NSCT) domain is presented and used to determine which coefficient is from the focused region. Then, based on the imaging(More)
For fusion of multifocus images, a novel image fusion method based on multiscale products in lifting stationary wavelet (LSWT) domain is proposed in this article. In order to avoid the influence of noise and select the coefficients of the fused image properly, different subband coefficients employ different selection principles. For choosing the low(More)
—Group buying auction(GBA) is seen as an effective form of B2C electronic commerce. GBA could not be directly applied to B2B transactions. This paper establish the evolutional group buying auction (EGBA) for B2B commodity trading based on GBA. First, the EGBA model is presented, and the key algorithms are introduced. Then Complicity Problem in EGBA is(More)
