以下是Line Gauss算法的基本原理: 首先,该算法对图像进行高斯模糊滤波处理,这一步的目的是减少图像中的噪声,并平滑图像,使得后续的线条提取更为准确。 接下来,算法进行粗定位线条位置,这一步是为了减少后续运算量,提高运算效率。粗定位线条位置后,Hessian矩阵被用来计算特征值,以检测线条的法线方向。Hessian矩阵是一个...
关于line-height 2019-12-11 22:22 −todo 当设置了多行省略的时候,最好再设个 line-height 和 height;如果是两行,height 要是 line-height 的两倍。 > 不然可能出现 PC 端看起来没有问题但是移动端出现问题的情况... 海客无心x 0 226 【HCIA Gaussdb】学习汇总-数据库管理(事务 权限 审计 OBDC JDBC...
* Calculate the parameters Sigma, Low, and Highforlines_gaussif(MaxLineWidth < sqrt(3.0))* 注意LineWidthMax < sqrt(3.0)将导致Sigma < 0.5,这没有任何意义,因为相应的平滑滤波掩码的大小为1x1。 * 为了避免这种情况,LineWidthMax被限制为大于或等于sqrt(3.0)的值,而对比度值则适用于反映这样一个事实: *...
