针对高精度的畸变图像,提出了一种基于最小二乘影像匹配的高精度畸变图像矫正算
法. 算法首先利用特征提取与边缘检测对图像进行预处理,并且将特征匹配与最小二乘算法相
结合,从而实现了图像与模板之间精确的子像素定位与匹配. 实验表明,该算法较好的解决了目前高精度畸变图像矫正算法中普遍存在的定位和匹配精度较差的缺陷,图像矫正效果良好,是一种有效的畸变图像矫正算法.(Image distortion for high-precision, a least-squares image matching based on high-precision image distortion correction algorithm. First of all, the use of feature extraction algorithm for edge detection and image pre-processing, and will feature matching with a combination of least-squares algorithm in order to achieve the image and the template between the sub-pixel accurate positioning and matching. The experimental results show that the algorithm has better accuracy of the solution to the current distortion prevalent image correction algorithm to match the accuracy of the positioning and less defects, image correction effect well, is an effective algorithm to correct image distortion.)

根据)EF 特性中的对比度敏感度，
即空间频率特性曲线，对图像进行二维多级小波分解，由分解后的各小波分量，提取各频段相应的亮
度、清晰度和相关度指标；然后将这三个指标的几何平均与频段加权系数的内积做算术平均，以此作
为图像质量的综合评价指标(According to) EF characteristic of contrast sensitivity, that is spatial frequency characteristic curve, the image is two-dimensional multi-level wavelet decomposition, the decomposition of the wavelet component, extract the frequency band corresponding brightness, clarity and relevance of indicators then the geometric mean of these three indices and the band doing weighted coefficient of the arithmetic mean within the product as a comprehensive evaluation of image quality index)

神经活动的微创直接读出的发展是当今神经科学面临的最大挑战之一。我们最近的工作表明，使用对神经递质释放特征敏感的磁共振造影剂，可以对分子水平的现象进行高分辨率功能磁共振成像（fMRI）。一个更有价值的贡献将是创造适合细胞内神经信号传导过程的分子功能磁共振成像的钙传感器。利用这些传感器进行的功能成像将结合MRI的无创性和全脑覆盖，以及已建立的光学钙神经成像技术的分子特异性和广泛适用性。钙依赖性功能磁共振成像（fMRI）将是分析动物神经回路的一项突破性技术，在人类中具有潜在的长期应用前景。技术
