前言：最近由于工作的關系，接觸到了很多篇以前都沒有聽說過的經典文章，在感嘆這些文章偉大的同時，也頓感自己視野的狹小。 想在網上找找計算機視覺界的經典文章匯總，一直沒有找到。失望之余，我決定自己總結一篇，希望對 CV 領域的童鞋們有所幫助。由于自己的視野比較狹窄，肯定也有很多疏漏，權當拋磚引玉了，如果你覺得哪篇文章是非常經典的，也可以把相關信息連帶你的昵稱發給我，我好補上。我的信箱 xdyang.ustc@gmail.com

文章按時間排序，排名不分先后，^_^。每一行最后一欄是我自己加的注釋，如果不喜歡可以無視之，如果有不對的地方還請告訴我，免得繼續出丑。 給出的文章有些是從google scholar或者citeseer上拷貝下來的，所以有鏈接。所有的文章在網上都很容易找到。有空的時候我會把它們全部整理出來，逐步上傳到ishare.iask.sina.com
由于整理的很倉促，時間也很短，還有很多不完善的地方。我會不斷改進，并不時上傳新版本。

Geometrical wavelet 中的一篇代表 作 。 其 他 的 如 ridgelet, contourlet, bandelet 等在這里就不贅述了。研究這方面的很容易找到這方面的經典文獻。個人以為不研究這方面的看了后對自己的研究也不會有多大啟發。曾經以為這個方向會很火，到最后還是沒火起來。 我覺得原因可能是現在存儲和傳輸能力的大大提高，使得對壓縮的需求沒有那么大了，這方面的研究自然就停滯了，就如同JPEG2000沒有成氣候 |

TPO24 1
in my opinion, the popular palce is our national park.
for starters, there is a large square in the park so it is convenient for people to do outdoor activities.
For example, I always see people exercising themselves there.
The icing on the cake is there is also a lake in the park and the lake is really beautiful. It is really a good place to relax your self when you get tired in daily life.
So this is the place people like to go and the reason why people enjoy going there.

TPO24 4
In the reading material, it presents a concept about flagship species. It is a particular species to represent the theatened habitat to the general public.
In the lecture, the professor uses a example to illustrate this the bird macaw.
When the trees were cut down and cleared away, the population of the bird declined and so did the other animals in the habitat.
So people strated spreading the word macow about how the bird needed help.
in the end, a lot of people contributed money and helpd the groups set up protected land.The bird and other animals were saved.
So this example illustrate the concept flagship species.

it is worth doing sth.
it is worth the money.
TPO24 6
In the lecture, the professor presents two kinds of narrators to illustrate how to tell a story.
the first narrator is objective narrator. from this kind , you can know what they do and what they say but that is all.
for example a man and a woman are going for a trip and from objective narrator you could only know what they say and what they do.You need to make readers to fill in the blank.
But in the second narraor,omniscient narrator you can know not only what they say and do, but also what they are thinking about.
For example , if the couple want to visit a friend and the man is thinking you can know the man is nervous because he hasn't seen his friend for a long time.
題目:Do you agree or disagree with the following statement:
The friends that you can have fun with are more important than the friends that you can get help from.
In my perspective, I think people who can help you are more important to someone's life because this kind of friend will play a key role to rescue you from bad situation you meet in life. And also, as you can image, in fact having fun is just one special kind of helping so according to those reasons I have to disagree the statement.
First of all, the friend who can help you will have a positive influence on you so that you can improve yourself. For example, when you are in university, a friend who can help you may study with you and you could discuss how to solve the assignment your teacher gives; And also, when you find a job, this kind of friend could teach you the skills you need in the company and this skill may be very significant so that you can have a good performance. However, another kind of friend can't do this, and in fact, usually they could have a negative effect on you because all things they know are having fun.
More importantly, a friend who can help you may give you a hand in emergency situation. In this situation, the most important thing is not your happiness but your life. All external expectation, all fear of embarrassment will fall away in the face of death. Supposing you are suffering a car accident, this kind of friend could call 911 at the first time and sent you to the hospital. But on the other hand, the other kind of friend may just watch how you are dying because they don't know how to do in this case. They know nothing but having fun. If you can't make sure your safety, according to Maslow's hierarchy of needs, you have no chance to pursue higher achievement.
But this kind of friend is still indispensable because they inevitably play a role in your life, you can receive your happiness when you get boring in your life. You can go shopping with him; you can watch movie with him; and also when you feel lonely you can go for a walk with him. But we need to emphasize is though this kind is also important, a friend who can help you is more significant in your life and you must treasure your relationship because it may last life long.

1.題目:Do you agree or disagree with the following statement? People are now easier to become educated than in the past.
At present, a growing number of people will choose to study in university or at least in highschool so they could gain enough knowledge to live a good life. According to a famous survey conducted by a prestigious company called SurveyMonkey, %89.7 of people in the world have education experience in the college or in the highschool while the rate will decrease to %37.6 before World War 2.So in my opinion, I strongly agree the statement, people are easier to be educated now.
First of all, as you can image, with the development of the society, the people in 21st century have no worry about the physiological needs. It means we don't need to care much about food , water or heat source ,which is the most basic need for life and we can pay more attention on education or something you really have interest. According to Maslow's hierarchy of needs, that is to say ,it will be easy for you to pursue your self-actualization, like education. However, people in the past is easier to suffer war or disease. For example, supposing you are a boy living in World War 2, would you pay much attention on education when the food or shelter is still a big problem?
More importantly, the scientific power will play a significant role in education, making it easier for people to get education. For example, you can simply search materials you need on the internet by clicking your mouse several times; you can use MSN to communicate with professors all over the world without flying to the city where the professor are; and also you are able to use some multi-media devices to help you understand the complex questions such as projector. With the help of modern science and technology, there is no doubt that we can obtain a good education in a easy way.
However, we can't hold an absolute view about this issue because human itself also play a very important role in education. Even though there are a good environment and state-of-the-art technology in modern society, it will mean nothing if you just don't want to learn. But, over all, it is true that people are easier to be educated than in the past.
