Sight Beyond Sight: Week 08 - "Leap Week"
http://yi-ihpc.blogspot.com/2008/02/week-08.html
Tuesday, February 26, 2008. Week 08 - "Leap Week". The demo program "moveresize" is able to work with laser. Thresholding of image affects the detection of laser blobs. Lower thresholds makes the laser dot highly visible but introduces more false positives. With higher thresholds, the laser "drops" once in awhile, so I've added loss tolerance for two frames after my program doesnt pick up the laser. Kevin simplified Lightdraw into three particular areas the team has to look into. Taken OpenCV motion temp...

Sight Beyond Sight: Week 13 - Back to my blogging routine
http://yi-ihpc.blogspot.com/2008/04/week-13-back-to-my-blogging-routine.html
Wednesday, April 2, 2008. Week 13 - Back to my blogging routine. Spent the day revising my linear algebra. I also came across an interesting gesture article called the " $1 Gesture Recogniser. I've tested the applet and its fairly accurate for such a small piece of code. It will be great if I can add it to Lightdraw package as a gesture recognition module. Now I've got really accurate laser to screen pixel mapping. Yeah! Very soon I've got to develop a multiuser capable application since I am not able to...

Sight Beyond Sight: Week 14 - The Teapot from 1975, Utah.
http://yi-ihpc.blogspot.com/2008/04/week-14.html
Monday, April 7, 2008. Week 14 - The Teapot from 1975, Utah. I've stumbled upon a few videos related to the OpenTouch project that I've mentioned last Friday, 0404. Introduction to MacLibre and OpenTouch. Http:/ video.google.com/videoplay? Compiling OpenTouch on Linux and Mac OSX. Copy /oscpack/MakefileLinux over /oscpack/Makefile. Change "INCLUDES = -I./" into "INCLUDES = -I./ -I./ip/"! Some related files posted on GSoC file repo. Http:/ groups.google.com/group/google-summer-of-code-discuss/files. Recor...

Sight Beyond Sight: August 2008
http://yi-ihpc.blogspot.com/2008_08_01_archive.html
Friday, August 8, 2008. 1 Gesture Recogniser by Wobbrock, J. O. et. al. adaptation in C. The original codes can be found at http:/ depts.washington.edu/aimgroup/proj/dollar/. I made a C adaptation of the original C# version to use with OpenCV during my internship. I've uploaded a copy here for academics to use in their C projects with as little code change as possible. For simplicity, the code follows a singleton pattern. Http:/ www.comp.nus.edu.sg/ situyi/DollarRecogniser/. Vector point gesturePts;.

Sight Beyond Sight: Week 09 - Beginning of my Interim Report
http://yi-ihpc.blogspot.com/2008/03/week-09.html
Friday, March 7, 2008. Week 09 - Beginning of my Interim Report. We had a Lightdraw presentation to SIGGRAPH Asia 2008 correspondents, and I was surprised by the appearance of my Computer Graphics professor, Dr. Huang Zhiyong. Turns out that he's a member of SIGGRAPH Singapore. First meeting with open source committee today. We plan to have a custom IHPC OpenSource webpage for Lightdraw instead of the usual SourceForge-ish layout. Whackapeng can now be played with variable number of players and avatars.

Sight Beyond Sight: January 2008
http://yi-ihpc.blogspot.com/2008_01_01_archive.html
Tuesday, January 29, 2008. Week 04 - Triggering Events. Went to a local precision optics company to sample the 532nm bandpass and 650 longpass filters. The red longpass worked really well and the green laser point was not visible at all despite its high intensity. The laser dots appear as the brightest pixels when the webcamera were fitted with the respective filters. Rebuilt one of the USB infrared pens to a battery operated one instead. The end result works but did not look pretty at all. The paper has...
