7/24 weekly update

1.這禮拜大概用了一下Visual C++ 2010 並使用OpenCV影像處理的API,一開始下載完OpenCV,按照安裝的步驟設定,也上網查了一些簡單的程式範例來測試,但出現了一個問題,讓我卡了好幾天,我遇到的是每次debug完,系統總是顯示"您的電腦遺失opencv_core246d.dll",但詭異的是,照著檔案路徑去找,會發現我的檔案並沒有遺失,不管是我重新安裝OpenCV或者是下載其他版本的OpenCV,除錯時永遠都有這個問題,讓我的程式無法執行,最後到OpenCV的官網查詢,終於找到解決方法了(點我看方法),我想我之後要多多利用這個官網了,之後應該會遇到更多類似的問題
ps.遺失的檔案中246代表OpenCV下載的版本,246代表OpenCV2.4.6的版本

2.這禮拜到師大跟那邊的學長姐學了一些Biodex(等速肌力儀),Biopac訊號擷取系統(加速規),EMG,Vicon(動作分析系統),Kistler force plate(測力板)的操作方法,還有一些數據的分析,我發現這些儀器很多都是用到電子相關的東西(ex.1.Trigger-->他的原理就是類似正極觸發,負極觸發的東西,他的作用是讓不同儀器進行同步 2.還有比如EMG收到的肌電訊號,之後必須用低通濾波器過濾得到有用的訊號(因為人的肌肉發出的訊號都在20HZ到500HZ之間,超過這範圍的就不是人體的肌電訊號(也就是雜訊),需要濾波),而且有趣的是他的介面很像Matlab的Simulink)

心得:這禮拜的進度有點緩慢,打工也一起加進來了,繼續加油了!

1. This week, I use OpenCV on my Visual C++  2010 , and try some simple programs. I got opencv_core246d.dll could not found error message after debug. After trying lots of way,I finally solved the problem.(Click to get the answer)

ps. The number 246 in "opencv_core246d.dll" means the Version of OpenCV.

2.I have learned how to use Biodex,Biopac,EMG,Vicon, Kistler force plate, and some data analysis skills in NTNU this week. I found that the some concepts of the equipment design are common with electronic knowledge.(ex. trigger--> Used to synchronize different equipment. , EMG--> The original signals from EMG have too much noise, so we have to use lowpass filter to get the useful signals (because the signals from the people are between 20Hz~500Hz. ). By the way, It's interest that the interface of lowpass filter in EMG is similar to Simulink.) 

Note: The schedule in this week is delay. Keep going!

7/18 meeting

1.這禮拜的meeting大部分的時間是聽學姊的論文口試報告,學姊的論文內容是將老師的影像追蹤系統應用在注意力缺陷過動症(ADHD)的學童上面,並透過在課堂上的影像追蹤去分析ADHD學童與一般學童在課堂上的差異

2.查了一個禮拜的MLE,看了一些paper,MLE是在統計上常使用的方法,在影像分析上,是用來尋找不完整資料的可能分布方法,很多有關影像追蹤的論文,程式中都有使用到這個概念,但我離寫出程式還有一大段很大的距離

3.老師手邊的儀器,有幾台攝影機,但具有高速攝影的功能,這部分可能還要再去確認一下

4.目前想使用的程式編輯器是Visual C++,一方面這是以前有碰過的編輯器,一方面這也是老師建議我使用的,他說他之前用C++ Builder寫到後來有很多問題,但我還想再查詢一下相關資料,也許還會再更改

心得:
1.到這禮拜結束前,還是有陸續去師大幫忙做一些腳踏車Fitting的實驗,另外在北市大運器所這也待了一個禮拜,我覺得兩邊最大的差別是,師大的學長姐對於運動科學方面真的很專業,每次跟師大的學長姊做完實驗都學到好多運動科學的知識,在北市大,學長姊的背景算是比較多元的,但在影像處理的方面,我可能必須自己尋找資源了,查詢更多的資料

2.meeting完後,發現學姊似乎快爆炸了,有幾篇期刊論文要投,老師給的工作份量,似乎不少,算是比較硬的,我想幾個月後,我應該也會蠻爆炸的,我必須在暑假先調適好,多詢問學長姐

3.現在雖然大概知道我的研究方向,但其實還是很模糊的,老師雖然是丟給我影像追蹤的方向,但我覺得還有很多需要和老師討論,但在討論之前,我必須再多看一些資料,和老師討論才是有意義的討論

4.有些事情真的是要實際去參與才會了解,多觀察,多聆聽,才一個禮拜,我已經覺得有些事情並不是我想像中的樣子,也許我要到最後才會知道我的選擇到底是不是對的,最近真的太多負面情緒,我相信在未來壓力一定不小,我得慢慢調適,莫忘初衷

1. In this week's meeting, senior sister in school reported her paper, and paper is about  "Using Image Tracking System To Analysis The Different Between ADHD Students And Normal Students". Which is combined the Image Tracking System and Special Education.

2.Having searched the information of MLE for one week, I have almost understanded the concept of MLE.
It's a statistics tool . In image tracking Programming ,it's used to find out the incomplete information. But I have to search more informations to figure out how to program.

3.The equipment for me to develop image tacking system is a general camera which have High-speed photography function . I have to figure out how to combine the camera and the program.

4.So far , the program language I want to use is Visual C++ ,but i have to study more information to figure out if it's the best choice .

ps.
1. Until this week , I have done some experiment about Bike Fitting with NTNU students, I think the most different between my institute and NTNU is that the students of NTNU Sport Science Institute are more professional about sport science knowledge. In our Institute, the background of students are more diverse.But in the image tracking , I have to find more resource to get better.

2.I think that after few months ,I would be very busy. I should adjust myself to get into new situation quickly.

3. Although my research direction is determined , It's still blurred and indistinct. I have to study more paper and find more information to figure out.

4.After my first week of my master's degree career ,It's a little different with what I thought before. Maybe I would know if it's a right decision until I graduate. This days, I'm in a bad mood. I should  learn how to adjust ,because there will be more challenge. In the end, wish me never forget my goal.

7/9 meeting

1.指導教授給我的研究方向是影像追蹤,至於用甚麼程式撰寫,需要我自己決定,希望大家能給我點意見,追蹤的項目,則是由另一外具有體育專業背景的學姊給我意見,我該開始看paper了
2.老師也要我去找出怎麼將很多組的二維向量分辨出最相近的兩組,但在這之前老師希望我去搞懂MLE,MPE兩種統計方法是甚麼

心得:下禮拜之後我的暑假就結束了,老師也開始丟東西給我了,感覺跟大學真的不一樣,老師丟問題給你,你想辦法figure out,不知道自己能不能解決,也不知道自己現在的決定是不是對的,反正就盡力做吧!

1.The direction of my research is decided : The Image Tracking. Now,I have to find out which program editor is suitable for the tracking. Otherwise, the objects I have to track aren't decided. I think I have to study more papers to figure out.

2. My supervisor wants me to figure out is what is the difference between MLE and MPE. Maybe the conceptions of  MLE/MPE are useful for me to write the program. Another question is how to find out the closed motion vector from many motion vectors, I have totally no idea about that........


Note: My summer vacation will be over next week. It's the whole new life and really different to the college! Supervisor give you some advices ,and all you have to do is solving  problems and figure out.Hope I can do my best to take the challenges in the future!
