提取信息

In this paper,a new combination method has been applied to delineate and extract water body,using Enhanced Thematic Mapper data.

针对已有方法无法准确提取河网支流和细小水体信息的缺点，提出了一种水体信息综合提取方法。

This method was applied and validated in Fuyang City, Zhejiang Province, and the information extraction precision was up to 80.5 %, which was 20 % higher than that of MLC （maximum likelihood classification） method.

实例研究表明，该信息提取方法较为有效，尤其是在树种信息提取方面具有一定的研究和应用潜力，同时也为浙江地区应用遥感技术研究虫害提供了一定的技术支持。

First, the proposed scheme uses contourlet transform to extract multidirectional and multiscale texture information, and then obtains the feature points invariant to the affine transformation from the low and middle directional subbands by Harris-Affine detector. Second, the feature regions are adaptively computed by the feature scale of the local structure and normalized by U transform. The watermarking is embedded adaptively in those characteristic regions which are normalized. Finally, by vector quantization, several copies of the watermark are embedded into the no overlapped local feature regions in different directional subbands.

首先，用Contourlet变换提取出多尺度、多方向的纹理信息；再用Harris-Affine检测算子从变换域的中、低频方向子带中提取出仿射不变特征点，结合自适应局部结构的特征尺度确定特征区域，并用U变换对其归一化处理，水印就自适应地嵌入到归一化后的区域中；水印嵌入采纳矢量量化的策略，将水印信息重复嵌入到不同方向子带、多个不相交的局部仿射不变特征区域。

Firstly,surd or sonant judgment with each voice frame is done,then the multi-scale wavelet analysis is done only on the sonant frames to get pitches.In order to get accurate pitches,the intervals of local modulus maxima of dyadic wavelet coefficients are corrected according to amplitude information and appearance probability information.

针对这一问题，提出一种基于小波变换的基音周期提取改进算法，将TEO算子与二进小波变换结合起来，首先进行清浊判定，然后只对浊音帧采取多尺度小波分析提取周期，提出用幅度信息和出现概率信息校正二进小波模极大值间距，从而得到准确的周期。
