Description: zemax源码：
This DLL models a standard ZEMAX surface type, either plane, sphere, or conic
The surface also demonstrates a user-defined apodization filter
The filter is defined as part of the real ray trace, case 5
The filter can be used at the stop to produce x-y Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y.
The amplitude apodization is of the form EXP[-(Gx(x/R)^2 + Gy(y/R)^2)]
The transmission is of the form EXP[-2(Gx(x/R)^2 + Gy(y/R)^2)]
where
x^2 + y^2 = r^2
R = semi-diameter
The tranmitted intensity is maximum in the center.
T is set to 0 if semi-diameter < 1e-10 to avoid division by zero. -ZEMAX source: This DLL models a standard ZEMAX surface type, either plane, sphere, or conic The surface also demonstrates a user-defined apodization filter The filter is defined as part of the real ray trace, case 5 The filter can be used at the stop to produce xy Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y.

Description: 图像识别，包括人脸识别和虹膜识别，在数字图像中虹膜位置的有效定位是虹膜识别的关键问题。用一种基于主动轮廓线模型的方法定位虹膜的位置，先用灰度投影法检测出瞳孔内的一点作为瞳孔的伪圆心，该圆心只要能落在瞳孔内部即可。-Image recognition, including face recognition and iris recognition, iris position in the digital image of the iris recognition and effective positioning is the key issue. Using a model based on active contour method of positioning the iris position, the first gray projection method used to detect a point within the pupil as a pupil of the pseudo-center of a circle, the center of a circle can be as long as it falls within the pupil.

Description: Edge detection result should be enhanced using linear method like Median filter to
remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the
centre of the pupil by counting the number of black pixels (zero value) of each column and
row. Then get each row and column that has the maximum number of these black pixels.
Then determine the center by simple calculation according to the image coordinate to set it
correct on the image, consequently we can determine the radius of the pupil. Thus we can find
the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to
locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms
of circle and ellipse.
