该程序采用opencv读取印章RGB值，绘制4通道png格式的电子印章

单目摄相机标定！OpenCV实现，标定图像，标定结果。(Monocular camera calibration! OpenCV realization, calibration image, calibration results。)

Object detection (or rather, recognition) is one of the fundamental problems in computer vision and a lot of techniques have come up to solve it. This is a Project about Real-time object detection in OpenCV using SURF.

通过形态学滤波操作，能够实现如下功能：消除噪声、分割独立的图像元素、在图像中连接相邻的元素、寻找图像中明显的极大值区域或极小值区域、求出图像的梯度

本文主要介绍下opencv中怎样使用hog算法，因为在opencv中已经集成了hog这个类。其实使用起来是很简单的，从后面的代码就可以看出来。本文参考的资料为opencv自带的sample。 　　开发环境：opencv2.4.2+Qt4.8.2+ubuntu12.04+QtCreator2.5. 　　实验功能： 　　单击Open Image按钮，选择需要进行人检测的一张图片，确定后自动显示出来。该图片的大小没限制。 　　单击People Detect按钮，则程序会自动对该图片进行行人检测，且将检测到的效果显示出来，即用1个矩形框将行人框出来。 　　单击Close按钮，退出程序。(This article describes how to use the next opencv the hog algorithm has been integrated in the opencv hog this. In fact, it is easy to use, can be seen from the code behind. Reference information in this article comes with sample for opencv. Development environment: opencv2.4.2+Qt4.8.2+ubuntu12.04+QtCreator2.5 experimental feature: Click the Open Image button to select a picture of the need for people detection, to determine automatically displayed. No limit on the size of the picture. Click the People Detect button, the program automatically the picture of pedestrian detection, and the detected results show a rectangular box, pedestrian box out. Click the Close button to exit the program.)

C# SDK for Face++ 人脸检测与分析 检测给定图片(Image)中的所有人脸(Face)的位置和相应的面部属性 检测模式可以是normal(默认) 或者 oneface 。在oneface模式中，检测器仅找出图片中最大的一张脸。 可以是none或者由逗号分割的属性列表。默认为gender, age, race, smiling。目前支持的属性包括：gender, age, race, smiling, 可以为图片中检测出的每一张Face指定一个不包含非法字符且不超过255字节的字符串作为tag，tag信息可以通过 /info/get_face 查询 检测给定人脸(Face)相应的面部轮廓，五官等关键点的位置，包括25点和83点两种模式。(Face Detection and Analysis Detecting the location and corresponding facial attributes of all faces in a given image The detection mode can be normal (default) or oneface. In oneface mode, the detector finds only the largest face in the picture. It can be none or a comma-separated list of attributes. The default is gender, age, race, smiling. Attributes currently supported include gender, age, race, smiling. Each Face detected in a picture can be tagged with a string that does not contain illegal characters and does not exceed 255 bytes. The tag information can be queried by / Info / get_face. The location of key points such as facial contour and facial features for a given face (Face) is detected, including 25 points and 83 points.)

说明：  相机自标定有完整的例子halcon提供了一种自标定的算子，它可以在不用标定板的情况下，标定出相机内参（无焦距），相对于多幅标定无法获取相机的外参(There are complete examples of camera self calibration. Halcon provides a self calibration operator, which can calibrate the camera's internal parameters (without focal length) without using a calibration board. Compared with multi frame calibration, the camera's external parameters cannot be obtained)

说明：  标准粒子滤波算法，用于地形匹配，对初学者具有参考价值(Standard particle filter algorithm for terrain matching)
