Elevated serum homocysteine has been shown to be a risk factor for hypertension, cardiovascular disease (CVD), and type-2 diabetes mellitus (T2DM).We characterized the relationships between the serum levels of homocysteine, folic acid, and vitamins D2, D3, and B12 in patients with T2DM, CVD, and hypertension in Shanghai, China. The levels of these serum(More)
For the existence of speckle in SAR image, it is very difficult to obtain good segmentation result with traditional methods. In the paper, a new method of SAR image segmentation is proposed with the combination of the features of SAR image and multi-resolution analysis of wavelet. First, texture features are abstracted in wavelet domain. Second, SAR image(More)
An image fusion method of multi-spectral image and panchromatic image based on the nonsubsampled Contourlet transform (NSCT) is proposed by analyzing the design and implementation of the filter bands of the NSCT. The multi-spectral image is decomposed with the IHS (Intensity, Hue, Saturation) transform, and the I, H, S, component are gotten. The I component(More)
To play the advantages of a variety of remote sensing data, the application of remote sensing image fusion is a very important choice. Remote sensing image fusion is large in computing capacity and time-consuming, and with the development of modern remote sensing technology, the amount of various remote sensing data obtained is larger and larger, how to(More)
With the development of modern remote sensing technology, a variety of earth observation satellites could continue to tremendously provide image data of different spatial resolution, time resolution, spectral resolution remote sensing, and the remote sensing data obtained is increasing with great capacity, which forms multi-source image pyramid in the same(More)
Classification is achieved by Markov random field filtering on the original data. The result is a series of segmented maps, which differ in the number of (unsupervised) classes. For a (compatible) supervised approach, only the first and last step have to be applied. Results are discussed for the agricultural areas Flevoland in The Netherlands (AirSAR(More)
With the development of modern remote sensing technology, a variety of earth observation satellites could continue to tremendously provide images of different spatial resolution, time resolution, spectral resolution remote sensing, and the remote sensing data obtained is increasing, which forms multi-source image pyramid in the same area. In such cases, in(More)
Development and environmental protection constitute an organic whole. In China, it is in the stage of rapid development of society, China is faced with many environmental problems,improving the level of the ecological environment monitoring and management is particularly important. Because of the technical limitations of the traditional environmental(More)
For the speckle consisted in Synthetic Aperture Radar (SAR) image,good result of SAR image segmentation can not be gotten with traditional methods. In this paper,a new method of SAR image segmentation is proposed with the combination of fuzzy neural network and the statistical feature of SAR image. Firstly, texture features of SAR image(More)
