[Hyperspectral image classification based on 3-D gabor filter and support vector machines].

A three-dimensional Gabor filter was developed for classification of hyperspectral remote sensing image. This method is based on the characteristics of hyperspectral image and the principle of texture extraction with 2-D Gabor filters. Three-dimensional Gabor filter is able to filter all the bands of hyperspectral image simultaneously, capturing the specific responses in different scales, orientations, and spectral-dependent properties from enormous image information, which greatly reduces the time consumption in hyperspectral image texture extraction, and solve the overlay difficulties of filtered spectrums.

[A method of object detection for remote sensing-imagery based on spectral space transformation].

Object detection is an intermediate link for remote sensing image processing, which is an important guarantee of remote sensing application and services aspects. In view of the characteristics of remotely sensed imagery in frequency domain, a novel object detection algorithm based on spectral space transformation was proposed in the present paper. Firstly, the Fourier transformation method was applied to transform the image in spatial domain into frequency domain.

[Hyperspectral remote sensing estimation models for snow grain size].

Snow grain size is a key parameter not only to affect the energy budget of the global or local region but also characterizing the status of snow vapor transport and temperature gradient. It is significant to monitor and estimate the snow grain size in large area for global or local climate change and water resource management. Recently, remote sensing technology has become a useful tool for snow grain size monitoring and estimating.

Global analysis of in vivo EGR1-binding sites in erythroleukemia cell using chromatin immunoprecipitation and massively parallel sequencing.

Early growth response gene 1 (EGR1) has been implicated in megakaryocyte differentiation induced by phorbol ester. But the molecule mechanism of EGR1 in this process has not been widely investigated. The identification of direct EGR1 target genes in a global scale is critical for our understanding of how EGR1 contributes to this process.

[Study on the genotyping of single nucleotide polymorphisms for a large number of samples by three-dimensional polyacrylamide gel-based microarray method].

Objective: To genotype single nucleotide polymorphisms (SNPs) in a large number of samples by applying three-dimensional polyacrylamide gel-based microarray.

Methods: The method relies on copolymerization of acrylamide-modified PCR products with acrylamide monomers and acryl-modified slides to prepare gel-based microarray. Then array is hybridized with a pair of specific probes and the two universal dual-color fluorescent detectors labeled with Cy3 or Cy5 respectively (Tag1 and Tag2).

An improved gel-based DNA microarray method for detecting single nucleotide mismatch.

3-D polyacrylamide gel-based DNA microarray platforms provide a high capacity for nucleic acids immobilization and a solution-mimicking environment for hybridization. However, several technological bottlenecks still remain in these platforms, such as difficult microarray preparation and high fluorescent background, which limit their application. In this study, two new approaches have been developed to improve the convenience in microarray preparation and to reduce the background after hybridization.
