Far-field focusing with superresolution aided by a proposed metallic plate is investigated in this paper. The proposed near-field structure can be employed to distinguish point-like sources with subwavelength distance and enhance the field strength based on the spoof surface plasmon polaritons theory, and by the simulations of near- and far-field spectrums, it can be found that some near-field evanescent...
In this paper, we propose a two-step approach for the super-resolution reconstruction of video sequences based on the degraded model. Firstly we use the sparse principal component analysis and the linear minimum mean square-error estimation method to remove the noises from the degraded video sequences. Secondly we adopt the Newton-Thiele's vector valued rational interpolation which is one of the nonlinear...
In order to overcome the existing fruit recognition method only for single feature recognition which leads the problem of lower recognition rate, this paper proposes a recognition method based on multi-feature and multi-decision. Firstly, we preprocess the fruit image which is to be classified, separateing foreground and background, and then we divide the target area. Secondly, in order to take full...
A remote sensing image fusion algorithm based on nonsubsampled contourlet transform (NSCT) and energy entropy is proposed in this paper. NSCT has characteristics of good multiresolution, shift-invariance and high directionality. It can give an asymptotic optimal representation of edges and contours in image. The local energy is robust in the representing and locating of all kinds of image features...
In scalable video coding, spatial scalability is a layered video representation with different spatial resolutions for the same video signal. Inter-layer motion information prediction is a method of improving coding performance for spatial scalability. In this paper, a multi-domain motion vectors prediction coding method for spatial scalability is proposed based on inter-layer motion information prediction...
The curvelet is more suitable for image processing than the wavelet, able to represent smooth and edge parts of image with sparsity. In addition, the representation contains more directional information. The primary experimental results show its potential in image processing. A watermark algorithm based on curvelet transform and Arnold transform is represented. Firstly the digital watermarking is...
