Though comparing Canny operator and center B spline dyadic wavelet, the following conclusion is proven in this dissertation: a Center B spline function has tight support and Canny operator hasn't. b Center B spline function asymptotic convergence to Gaussian function and the derivative of Center B spline function asymptotic convergence to Canny operator. c The derivative of fourth order center spline B function is more suitable as a optimal edge detector than Canny operator. d Center B spline function can balance the smoothing and approximation of original data, and the fourth center B spline function is the only optimal solution of two order smoothing problem. e The error between the valve of time-frequency uncertainty of the fourth center B spline function and the lower bound of time-frequency uncertainty does not exceed 0.143% of the lower bound. f The derivative of center spline B function can construct a stability dyadic wavelet and can give a fast algorithm for multiscale edge detection, but Canny operator can do neither.

作者给出了Canny算子与中心B样条二进小波严格的比较证明，得出如下结论：a中心B样条函数具有紧支集，Canny算子不具有紧支集。b中心B样条函数的极限收敛于高斯函数，中心B样条函数的导数收敛于Canny算子。c四阶中心B样条函数的导数比Canny算子更接近最佳边缘检测滤波器。d中心B样条函数比高斯函数更能兼顾对原函数平滑和逼近的折中要求，并且四阶中心B样条函数是二阶逼近问题的唯一最优解。e四阶中心B样条函数的时频测不准关系值与时频测不准关系下界的逼近误差不超过0.143％。f中心B样条函数的导数可以构成稳定的二进小波，存在快速的多尺度算法；而Canny算子不构成稳定的二进小波，无法给出快速的多尺度算法。

与center相关的网络解释 [注：此内容来源于网络，仅供参考]

center：中心

举例来说,虽然理论上"中心"(center)对所有的图形都是一个有效的概念,但当你要维护一个三角形的"中心"的时候,是一件非常麻烦的事情--对于三角形,当且仅当它确实被需要的时候,计算这个中心才是有意义的.

center：中锋

以往.大前锋往往就是要做苦工的.在场上他们少有接球单打的机会.但是现在篮球观念日新月异.大前锋也就慢慢在进攻方面有所加强了.这也正是大前锋今昔最大的差别.不过.一个好的大前锋.还是要以在禁区的苦工为主的.一个能抓篮板能防守.但是进攻能力不佳的球员.我们会称他是好的大前锋.但是一个很能得分却在篮板.防守上失职的球员

center：居中

大体DIV构架为上(nav)中(page)下(footer)三部分,其中中间部分(page)又分为左(left)居中(center)右(right)三列. 然而使用后却发现中间部分(page)DIV不能够自动适应,由于左(left)和右(right)高度比较固定,但居中(center)高度不固定,

center：中线

可能会有很多人问,为什么没有手部的引带呢?因为拉丁舞的高级阶段,动力都是由身体的中线(center)发出,手部只是力量的远端延伸. 手部引带动作其实是身体引带的延续.

center back：中后卫

后卫这片场地里也实行"分片负责制",有中后卫(center back)、左后卫(left back)和右后卫(right back). 有时为了防止被对手轻易突破防线,还要有一个拖后中卫(sweeper).
