The characters of different illumination conditions are studied and the corresponding algorithms of gray image edge detection are proposed. In normal condition, the Sobel operator can be used to get the image edge. When the illumination is faint, the image is first enhanced by the MSR, and then the variance threshold algorithm is employed. While the light is strong, the image edge can be got by gray expand. At last, the instance image is detected.

通过对不同光照情况下的图像特征分析，提出了不同光照情况下的图像边缘检测算法：正常光照条件下采用Sobel算子进行边缘检测；弱光照条件时先用MSR (multi-scale retine)进行图像细节增强处理，再利用类别方差自动门限法得到图像边缘；强光照条件下通过灰度扩展，将所感兴趣的灰度范围放大得到图像的边缘。

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。

This is really no different from code that tests whether an object reference is null before calling a method on the object, it just so happens that we're dealing with events here.

对于任何首先检查对象是否为null，再在对象上调用方法的代码而言都是这样，处理事件时也不例外。

RESULTS: Before remineralization, through SEM, short blunt eeptoma was found on the surface of lesions of samples in Chinese nutgall group and Ag（ NH3 ）2F group; while in NaF group, globular ecptoma was seen scattering on the surface of the lesions, together with laeune; in deionized group, there was Sharpey＇s fiber.

In view of the existing problems of traditional resource allocating networks, a design method for RAN based on rough set and orthogonal least square was proposed. Firstly, rough set was applied to intelligent data analysis for extracting typical characteristics from the training samples, and then OLS was used to select best centers as the hidden layer nodes.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.
