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。

In the four placebo-controlled studies evaluating radiofrequency denervation outcomes in patients with "confirmed"l-z joint pain, the only study that screened patients with MBB demonstrated positive outcomes,157versus only one of three that used diagnostic intraarticularin jections.158–160 Ultrasound-guided medial branchand intraarticular blocks have also been demonstrated to provide comparable accuracy to fluoroscopically guided injections, although they may be less likely to detect low-volume intravascular uptake and are less accurate in obese patients.161–164 Because MBB are technically easier to perform than intraarticular injections and involve anesthetization of the nerves to be lesioned, it seems more logical to use these blocks as a prognostic tool before radiofrequency denervation.

在四个设有安慰剂对照的对于&确诊&小关节疼痛的患者行射频神经消融后的结果的研究中，唯一一个用MBB筛选研究对象的实验表现出阳性结果，而其他3个用关节内注射筛选的实验中只有1个表现出阳性。超声介导下的内侧支关节囊内阻滞被证实较透视介导更精确，虽然其血管内吸收剂量较低且在肥胖的患者中精确性较差。由于MBB较之关节内注射技术上更简单，且能对受损神经进行麻醉，利用这种阻滞作为神经射频消融前的诊断方法较为合理。

Based on the relationship between the numerical aperture of the objective lens and scale pitch, this study chooses a suitable Plano-convex lenses available on the market, so as to approximate the diameter of the focusing spots to scale pitch. Also, by using the optical path of an optical encoder similar to the nanoscale, the changes in the surface profile of the scale can be measured directly, so as to obtain the two quadrature sinusoidal signals. By counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the scale can be obtained.
