论文摘要
我们提出了Laguerre Gauss变换的概括，以在涡流计量学中包括椭圆形内核。为此，我们拓宽了使用Laguerre Gauss变换（LGT）获得的原始伪场，通常包括循环的对称的高斯核心，以包括两个参数，即在两个垂直方向上的高斯滤波器的宽度，从而产生了一个稍微椭圆形的核。这允许产生一个非常紧密的涡旋家族，从而改善了同源物体的识别以及测量的精确性和位置。我们显示了激光生成的斑点和超声图像中的示例。
We propose a generalization of the Laguerre Gauss Transform to include elliptical kernels in vortices metrology. To that end, we broaden the original pseudo field obtained using Laguerre Gauss Transform (LGT) that usually includes circularly a symmetric Gaussian core to include two parameters, the widths of the Gaussian filter in two perpendicular directions, thus generating a family of slightly elliptical kernels. This permits the generation of a family of very close vortices that improves the identification of homologous ones and the precision and locality of the measurements. We show examples with laser generated speckle and in ultrasound images.
