几何库，来处理和可视化几何元素，如点，线，圆和椭圆，折线和多边形。(Geometry library to handle and visualize geometric primitives such as points, lines, circles and ellipses, polylines and polygons)

说明：  何凯明暗通道先验图像去雾算法，并用导向滤波进行透射图细化(He Kaiming's prior image defogging algorithm is used to refine the transmission image)

Abstract—Noninvasive ultrasound imaging of carotid plaques allows for the development of plaque-image analysis methods associated with the risk of stroke. This paper presents several plaqueimage analysis methods that have been developed over the past years. The paper begins with a review of clinical methods for visual classification that have led to standardized methods for image acquisition, describes methods for image segmentation and denoizing, and provides an overview of the several texture-feature extraction and classification methods that have been applied. We provide a summary of emerging trends in 3-D imaging methods and plaque-motion analysis. Finally, we provide a discussion of the emerging trends and future directions in our concluding remarks.

说明：  可以通过光流法来检测运动的目标，具有很好的效果，适合新手了解(It can detect moving target by optical flow method, and can detect moving target by optical flow method, which has good effect and is suitable for novice to understand)

Unix系统下，小波包变换的实现源码实例，，当然，稍作改动也可用于windows系统下。 (Unix systems, the instance of the wavelet packet transform source, of course, some minor changes can also be used in the windows system.)

通过求差分曲线，利用阈值分割算法对图像进行自动多阈值分割(image segment method)

说明：  利用k-means算法进行图像分割，效果较好(Using k-means algorithm for image segmentation is better)

图割算法 求图像的立体匹配问题 最大流最小割问题(graphcut stereomatching matlabcode)

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.)

用奇异值分解的方法实现图像的去噪，并且与其他的方法进行比较，较之其他的方法有了明显的提升(To eliminate the noise from signals and compared to others mothods，an depressing effect is gotten)
