这女人是谁？

有人认识这女人是谁吗？

我想读过 Image Processing 的学生都应该不陌生

对了！！
她就是常常出现在不同的书本里
每个 Image Processing method 就会拿她的尊容来做分析的俏丽女郎

而我也很好奇
她究竟是谁？
经过我Google 了一下，发觉她还蛮出名的

她的真名叫 Lena Söderberg , 瑞典模特儿，　
而这张照片，就是在1972 年11 月为PlayBoy 杂志拍的其中一张

而她的粉刺还特地为她作了首诗呢

Sonnet for Lena
O dear Lena, your beauty is so vast
It is hard sometimes to describe it fast.
I thought the entire world I would impress
If only your portrait I could compress.
Alas! First when I tried to use VQ
I found that your cheeks belong to only you.
Your silky hair contains a thousand lines
Hard to match with sums of discrete cosines.
And for your lips, sensual and tactual
Thirteen Crays found not the proper fractal.
And while these setbacks are all quite severe
I might have fixed them with hacks here or there
But when filters took sparkle from your eyes
I said, “Fuck this shit. I’ll just digitize.

by Thomas C

而现在的我更好奇了
为什么她这张照片会被选为Image Processing 主要的分析照片呢？
我又Google　了一下发现
这张照片背后原来有个好笑的故事

下面这整段故事我就不翻译了

Jamie Hutchinson in an article in the May 2001 newsletter of the IEEE professional Communications Society writes about the pictures history.

Alexander Sawchuk estimates that it was in June or July of 1973 when he, then an assistant professor of electrical engineering at the University of Southern California Signal and Image Processing Institute (SIPI), along with a graduate student and the SIPI lab manager, was hurriedly searching the lab for a good image to scan for a colleague’s conference paper. They got tired of their stock of usual test images, dull stuff dating back to television standards work in the early 1960s. They wanted something glossy to ensure good output dynamic range, and they wanted a human face. Just then, somebody happened to walk in with a recent issue of Playboy.

The engineers tore away the top third of the centerfold so they could wrap it around the drum of their Muirhead wirephoto scanner, which they had outfitted with analog-to-digital converters (one each for the red, green, and blue channels) and a Hewlett Packard 2100 minicomputer. The Muirhead had a fixed resolution of 100 lines per inch and the engineers wanted a 512 × 512 image, so they limited the scan to the top 5.12 inches of the picture, effectively cropping it at the subject’s shoulders.

A more amazingly amusing account that even discusses the debate regarding the picture can be found on the page of DAVID C. MUNSON, JR. of the CMU here.

An excerpt from his writing.

I think it is safe to assume that the Lena image became a standard in our “industry” for two reasons. First, the image contains a nice mixture of detail, flat regions, shading, and texture that do a good job of testing various image processing algorithms. It is a good test image! Second, the Lena image is a picture of an attractive woman. It is not surprising that the (mostly male) image processing research community gravitated toward an image that they found attractive. The Woody Allen buffs among you may be interested to know that the Lena image appeared in the movie Sleeper. Tom Huang pointed this out to me. In the scene where Allen awakes in the year 2173, he is asked to identify a number of artifacts from the past, including photographs of Joseph Stalin and Charles de Gaulle, and the issue of Playboy Magazine containing Lena.

and regarding the debate he writes:

Well, quite understandably, some members of our community are unhappy with the source of the Lena image. I am sympathetic to their argument, which states that we should not use material from any publication that is seen (by some) as being degrading to women. I must tell you, though, that within any single segment of our community (e.g., men, women, feminists), there is a complete diversity of opinion on the Lena issue. You may be surprised to know that most persons who have approached me on this issue are male. On the other hand, some informal polling on my part suggests that most males are not even aware of the origin of the Lena image! I have heard feminists argue that the image should be retired. However, I just recently corresponded with a feminist who had a different point of view. She was familiar with the Lena image, but she had not imagined that there could be any controversy. When I offered an explanation of why some persons are offended by the use of the image. she responded tartly. A watered-down version of her reply is, “There isn’t much of Lena showing in the Lena image. This political correctness stuff infuriates me!”

一小时的反思

今晚， 你 熄灯一小时了吗？

有位朋友对我说
有一天　他听电台时
那位 DJ 在电台呼吁大家熄灯一小时
那么想必各位一定烦恼在那一小时内可以做些什么呢？
没关系，　各位可以聚集几位好朋友一起看电影。。。。

我当场无言
ＤＪ　的出发点我是好的
但是，这样的观念
令我不禁怀疑
这一次的醒觉运动
真正醒觉的有多少人？
还是各位只是纯粹凑个热闹？

有多少人在这一小时的热情后恢复冷淡
直到明年今日

有多少人或许在那一小时内关了灯，
可是却开着全家的冷气机，一家大小待在电视前看电影？

又有多少人趁着各大商场关灯一小时的短短时间内趁火打劫？

我不敢想象

想令全球有醒觉的心
需要持之以恒的行动

希望各位爱惜你我共享的地球

呼~~ 暂时的完毕

终于考完唯一的一张 test 2 paper 了

只是暂时哦哦。。。

接下来的还有：
毕业论文
Assignment x 1
Presentation x 1

在大学里浮浮沉沉了很多年
对眼前的考试，功课， 不知所谓的讲师
腻了，真的累了

为何厌倦呢？
当Lecturer给你做一个Assignment， 而那个Assignment 是他的Research Title, 他只是利用你来帮他完成他的Research Title ... 这样的讲师， 倦吗？

当Lecturer 出的考试题目是完全没教过的，然后还有好戏在后头， 你说， 显吗？

算了，就来挨完了
睡个午觉，醒来又是一条龙 =)

2009新概念

无意中看到一篇感人的故事

當你步入生命終點，不能走、不能講、不能想、不能吃喝，
只能靠呼吸器，就快閉眼長逝，
醫生告訴你，只剩最後一次機會，
只給你最後兩小時，回到你以前熟悉的世界，你最想做什麼？

想了想
人生有太多遗憾
好像两小时不够用吖


他，在生命最後一刻，選擇包下戲院，陪一對兒女和癌症病童，看最後一場電影∼一場悲傷的史瑞克。

感人故事最后， 警惕大家要有2009 概念
我说
何止2009才应有的概念
应该无时无刻都持有这种观念啊。。

2009新概念

一個中心： 一切以健康為中心。
兩個基本點：遇事瀟灑一點，看事糊塗一點。
三個忘記： 忘記年齡，忘記過去，忘記恩怨。
四個擁有： 無論你有多弱或多強，一定要擁有真正愛你的人，
擁有知心朋友，擁有向 上的事業，擁有溫暖的住所。
五個要： 要唱，要跳，要俏，要笑，要苗條。
六個不能： 不能餓了纔吃，不能渴了纔喝，不能困了纔睡，
不能累了纔歇，不能病了 纔檢查，不能老了再後悔!

白色情人节

忘了哭

有种相遇注定终究没结果，但还是会让人默默地等待。
有种相爱注定是一种伤害，但还是让人对它流连忘返。
有种再会注定是一声叹息，但还是让人痛得伤痕累累。
有种直接注定是一种残酷，但没办法，爱情就是一种美丽的残酷

Watchmen 2009

昨天, 在临时抱佛脚的情况之下赶完了应该赶的东西( 赶完了? 暂时告一段落吧...)

然后跑去看了 Watchmen

这不是一套烂戏，绝对不是
只是两小时半里缺乏高潮，
让人有"哇, 还没end 啊?" 的感觉

最喜欢的还是那个Rorshach
整套戏最有个人风格的就数他了

总的来说
看完Watchmen,
觉得还好，有点郁闷，少了一份满足感

背叛

所谓的恒心，诚意
换来的只是一场背叛游戏
和虚假的眼泪

最熟悉的陌生人

分手后不可以做朋友 ，因为彼此伤害过
不可以做敌人， 因为彼此深爱过
所以变成了最熟悉的陌生人

厌倦

光军之翼

11/3/2009
这天将会是我的纪念日
纪念着我
在这里建立新天地

今天应该是赶着我的毕业论文的
因为沮丧的关系，无无聊聊的跑来了这里
再揾吉的开了一个属于自己的角落
无他，就想宣泄一些不满的心情

希望这里不会变成我的黑色地带
