2009-09-18 Hualian traveling (2)


 Hello!! See you again. ^^.
After the data, we went back to Tzu to find one member of our family, "Yi-Xiu  Lai"

 The one closer is "Yi-Xiu", and the other one had be one of the member in our lab. They were washing slides which had be coated with some protein on it.
 After night fall, we went to Yuan-Lai Hotel continousely killing our SD card memory.

 Yuan-Lai is the best place for people want to view the artificial night scenes in Hualian. Before we arrived, there were aready many people there. Although the weather was not good enough, sky was filled by clouds. We couldn't see any star in the sky.

 It's not easy to get photo at night, this photo was the best one in twenty photos that shot in the same view. Maybe i should buy a tripod when i bought this camera.


 This was thirth day of travling in Hualian.  Time is going to fast......

影像-疊圖

圖片
    疊圖怎麼做？ 有沒有更簡單的方法？ 這樣的想法時，過去的電腦玩家們也有一樣的問題，並提出了解決的方法。這方法還是開源的，是每個人都可以免費使用的喔。而你所需要做的事情，就是花一點時間收尋（感謝google大神吧）。     好的，讓我們回歸正題吧。影像疊圖，目前筆者接觸到的開源影像疊圖方法有兩種，一種叫 ImageJ , 一種叫 enfuse 。 在筆者的測試中ImageJ的疊圖效果會有點失真，玩家們可以自己測試看看，哪一個使用起來效果比較好。     在ImageJ部份，中文的介紹阿簡大大已經介紹過了（ 傳送門 ），在此就不再贅述。這裡要介紹的是在國外攝影玩家常用的開源方法, enfuse . enfuse 是由Andrew Mihal等開源大大所開發，因為這套軟體的疊圖相當不錯，所以目前也有很多的GUI被開發出來。linux以外的平台也可以使用（ 傳送門 ）（GUI是什麼？GUI，在我的不專業了解下，就是視窗化的軟體，簡單來說就是.... 不用打字，用滑鼠點點點就可以用的軟體）。       如果未來想要接觸更多的開源軟體，筆者建議可以試著接觸一些容易上手的linux作業系統分支，如ubuntu( 傳送門 )。目前微軟與ubuntu有合作，所以也可以考慮在微軟上安裝ubuntu，來使用下面介紹的方法。（微軟是什麼？ 欸～ 如果你買的不是蘋果電腦，基本上你的電腦裡的作業系統應該都是微軟的） 好的，以上是基本介紹，接下來讓我們看看enfuse怎麼使用吧～～ 首先你要有一組需要疊圖的圖片 （廢話！） 上方顯示的圖像，是針對同一個部位進行連續拍攝，但聚焦的位置不同。左上方的聚焦在靠近頭部的黑色素細胞，右下角則是聚焦在靠近嘴部的黑色素細胞。 接下來，打開linux中的terminal （終端機; 類似微軟的dos操作方式）。 如果玩家使用ubuntu，在儲存圖像的資料夾位置，右鍵點選open in terminal（用終端機開啟）。接著輸入指令： enfuse --exposure-weight=0 --saturation-weight=0 --contrast-we...

Bug!!!

Although it was not a short time after i make system upgrade to 8.04. I had never notice that i can only use wireless but not wired to connected internet until i moved into my new house. Yes, just like what you though. I had no choice but to use wired network to connect internet. It's a bug with the network driver, Realtek8168. Ubuntu did not loading the correct driver, r8618. It apply the wrong driver, r8619. In the situation, Ubuntu can sense wire and applying the r8169 driver to connect internet. However, it can not really make connection to Route and the information such like ip address or broadcast address all showed "0.0.0.0". Thanks to Dale Jefferson had solved the problem (although it's not really solved, i can use wired to make connection now.) To solve the problem need to install the correct driver, r8168. sudo apt-get install build-essential wget ftp://66.104.77.130/cn/nic/r8168-8.006.00.tar.bz2 tar -xjvf r8168-8.006.00.tar.bz2 cd r8168-8.006.00/src # and ...
