Description: 包括整个虹膜识别的预处理部分,分为多个函数部分,即简单图像增强,Canny算子提取边缘,Hough变换定位内外圆形边界进行风格,以及最后的归一化 -- 将圆环展为矩形。附带几张图像及自制的界面程序,并不是很完善,但整体的预处理任务已经较好的完成,如果进一步提高性能,可以先把Hough变换改为最小二乘拟和算法。-Cover the whole iris recognition pre-processing part is divided into multiple function part, that is, a simple image enhancement, Canny operator edge extraction, Hough transform internal and external circular positioning border style, and finally normalized Circle exhibition will be rectangular. Fringe images and made a few interface procedures, is not very perfect, but the overall pre-processing tasks have been better to complete, if further improve performance, first Hough transform can be replaced by least squares fitting algorithm.

Description: Circles
We can extend the Hough transform to other shapes that can be expressed parametrically. For example, a circle of
fixed radius can be described fully by the location of its center (x, y).
Think of each feature (edge) point on the circle as saying, ”if I’m on the circle, the center must be in one of these
places”. It turns out that the locus of these votes is itself a circle.
But what about circles of unknown size? In this case, we need a third parameter: the radius of the circle. So, we can
parameterize circles of arbitrary size by (x, y, r). Instead of casting votes in a circular pattern into a two-dimensional
accumulator, we cast votes in circles of successively larger size in a three-dimensional accumulator. Platform: |
