In this paper, the theory, algorithm, and experiment of automatic object detection and tracking are studied in depth. It is firstly pointed out that the essential of Mean Shift method is a special Newton-Gaussian method. A new method named Fast Mean Shift is established to stretch the conservative step of Mean Shift method. The convergence and validity of this new method are proved in theory. And it is also proved that the convergence speed of Fast Mean Shift is faster than that of Mean Shift. The contrast experiments of searching the maximum possibility density of random of data sets in plane and 3D space are done. The results show that this new method can reduce the iterations greatly. A new object tracking method based on Fast Mean Shift is built to improve the object tracking performance, which is shown in the face tracking experiment with the tennis sequence provided by the Ohio State University, and the car tracking experiment with the car sequence provided by Kalsruhe University. The face trcking experiment with highly noised images show that the object tracking method based on Fast Mean Shift has strong anti-jamming ability. A new fast color object detection technology based on characteristic color is established, which use characteristic color distribution to compute the characteristic color vector of any area in an image quickly. With the high performance search method, the fast object detection is achieved. At last, using object tracker based on Fast Mean Shift and color object detector based on characteristic color with the Kalman filter, PID controller, searial communication and other technologies, automatic object detection and tracking system with control system is built. The availability and anti-jamming ability of this system are verified by some object detection and tracking tests in different scenes.

本文对目标自动识别与跟踪进行了理论、计算、试验三方面的深入研究，主要包括：首次指出了目标跟踪技术中常用的均值迁移方法的本质为一种特殊的高斯-牛顿方法，改进了均值迁移方法步长取值保守的弱点，建立了快速均值迁移方法，证明了该方法的收敛性、有效性以及收敛速度优于均值迁移方法；进行了平面和3维随机分布数据集的最大概率密度搜索对比试验，试验结果表明，快速均值迁移方法大大减少了迭代次数；建立了基于快速均值迁移的目标跟踪方法，利用俄亥俄州立大学提供的乒乓球序列图像和卡斯鲁厄大学的汽车序列图像，对人脸和汽车目标跟踪性能分别进行了对比试验，并进行了高噪声人脸图像目标跟踪试验，结果表明，基于快速均值迁移的目标跟踪方法有效提高了目标跟踪性能，具有很强的抗干扰能力；建立了一种新型彩色目标自动识别方法，采用特征色彩分布函数实现了对任意图像区域特征色彩矢量的快速计算，建立了高效的搜索方法，实现了彩色目标的快速识别；将基于快速均值迁移方法的目标跟踪方法、基于特征色彩的目标识别方法与卡尔曼滤波、PID控制、串行通讯等技术结合，建立了带有控制系统的快速目标自动识别与跟踪系统，并在不同场景下进行了目标自动识别与跟踪试验，验证了快速目标自动识别与跟踪系统的有效性和抗干扰能力。

In the candidate face preprocessing sub-system, the algorithm proposed in this paper first filters the candidate face so as to eliminate the noises, and then extends in gray level up to adjust the contrast of image, and finally uses histogram equalization to adjust the mean value and square difference of images, realizing the gray level normalization.

2对于侯选人脸区域图象预处理子系统；首先对侯选人脸区域进行滤波以去除图象噪声，再做灰度拉伸以调节图象的对比度，然后用直方图均衡调节图象的均值和方差，达到灰度归一化的目的。

"Hazy" Good ambiguous name, yesterday in a rare fog enveloped the entire City, a very silly sense of visibility below 10 meters, just go out would be a kind of very exciting feeling, in that space of the Mist stay for a long time, feeling a boring person can not see anything, can only be seen a few zero-Mist dilute the flashing lights of the cars, you do not know what the status outside the 10 meters, or even the traffic lights, you do not know what you will face is how the situation, everything is unknown, that Mende feeling may just be time for everyone to face the unknown of a mind's instinctive reaction to fear.

"雾蒙蒙"好暧昧的一个名字，昨天一场罕见的大雾笼罩整个岛城，很懵懂的感觉，能见度低于十米，刚刚外出会有种很兴奋的感觉，在那种蒙蒙的空间里呆久了，感觉很闷，看不见任何东西，只能蒙蒙中见到几个零稀的车灯在闪烁，你可以不知道十米以外是怎样的状况，甚至是红绿灯，你也不知道你将面临的是怎样的状况，一切都是未知，那种闷得感觉，可能只是每个人面临未知时的一种内心恐惧的本能反应。

Sometimes, it's hard to hold onSo hard to hold on to my dreamsIt isn't always what is seemsWhen you're face to face with meYou're like a daggerAnd stick me in the heartAnd taste the blood from my bladeAnd when we sleep, would you shelter meIn your warm and darkened graveWill you ever take meNo, I just can't take the painBut would you ever trust meNo, I'll never feel the same...

有时候，坚持是奢侈，坚持梦想更加是奢侈，世界也不是它看起来的那样，可是当你望着我的时候，你的眼神象是一把利剑，深深扎进我的心房，舔着我内心的鲜血，熟睡之际，你会用你那温暖而又深沉的音调来保护我吗？你能忍受我的一切吗？不，那我就不能承受痛苦。你曾经对我深信不疑吗？不，那我的感受会反复无常。
