Nowdays,the infrared camera in our country can export video signal and digital image signal. The video signal can display on the screen through the general grab card, but the digital one can not be inputted into computer without special image grab card. In this paper, an infrared image grab card and the correlative program driver are designed based on the analysis of the universe technology.

通过对人脸图像奇异值的分析，证实了图像奇异值是图像在特定基空间分解得到的，这个基空间是由图像本身决定的。

Image smoothing, which is a commonly used means of digital image processing, image templates are thinking.

图像平滑处理，这是一种常用的数字图像处理手段，都是用图像模板的思想。

Shortcomings of Tikhonov regularization model in Sobolev space for image zoom in are analyzed and a digital total variation model with image inpainting for noisy image zoom-in is presented.

分析了利用Sobolev空间Tikhonov正则化模型对带噪图像进行放大的不足，基于图像的修复模型，提出带噪图像放大的数字全变差模型。

At first, the original image is divided into local image blocks (32×32), the quality of each local image is estimated by the corresponding spectral distribution.

实际应用中，自动指纹识别系统的性能在相当大的程度上受所采集的指纹图像质量的影响。

By fusing the IKONOS multi-band and pan image using several image fusion algorithms(IHS transform, PC transform, Gram-Schmidt transform and smoothing filter-based intensity modulation) and assessing the fusion image, indicates that qualitative comparison is too subjective, although many methods are provided for assessment when using quantitative methods, more bands and more methods should be used for their limitations, spectral curve comparison was the best method for appraising the result, spectral angle and geometry distance was introduced to appraise the spectral curve.

以IKONOS影像为数据源，对IHS、PC，Gram-Schmidt和基于亮度调节的平滑滤波四种融合算法进行融合处理，对其结果进行了评价。结果表明，定性比较主观性较强，定量比较方法虽多，但大都有一定的局限性，不同谱段的计算结果总有些差异。因此，定量评价时应该多选一些波段与评价方法才能获得比较客观的评价结果。光谱曲线的比较不失为一种比较好的方法，在对光谱曲线进行比较时本文引入了光谱角度和几何距离两种方法进行定量的比较。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
