A Bayer pattern image codec method based on Wyner-Ziv structure is proposed in this paper. At the encoder the pixel of Bayer pattern image is converted into four component images by means of structural separation and transformation. Three of them are transformed into frequency domain by the discrete cosine transform. We extended the Lloyd iterative algorithm and designed an optimal scalar quant...

Mayr and Meyer [MM] found ideals with the doubly exponential ideal membership property. Further investigations of the doubly exponential properties of these ideals can be found in Bayer and Stillman [BS], Demazure [D], and Koh [K]. Following a question of Bayer, Huneke and Stillman, the author has investigated in [S1, S2, S3] the properties of the primary decompositions and the associated prime...

As a promising electronic material, Ge nanowire (GeNW) has attracted much attention for its low band gaps, high mobilities, and unprecedented dimensions. This article reviews recent research and advancement on this topic and summarizes many aspects of GeNWs, including preparation, surface chemistry, physical properties, functional devices, and controlled assembly. It is shown that GeNWs can be ...

In this paper, we propose a new method for color image-based authentication that combines multispectral photon-counting imaging (MPCI) and double random phase encoding (DRPE) schemes. The sparsely distributed information from MPCI and the stationary white noise signal from DRPE make intruder attacks difficult. In this authentication method, the original multispectral RGB color image is down-sam...
