I am developing a sophisticated 3D reconstruction tool, for deployment in biological analysis. While this has additional applications in surface-based quality analysis for structural integrity and systems evaluation, the current objective is a tool to assist with wildlife monitoring. To ensure effective construction, I'm employing industry-proven development and design patterns. Yes, it is hilarious to have a daily scrum when its just me. Woohoo!

Ideal workflow. Left images shamelessly borrowed from Banff National Park, Canada. 3D model from 123D catch model.

Core objectives include:

  • Using RGB-D cameras to capture and model dynamic systems for practical purposes
  • Developing a system which can perform on generic models, without significant apriori information

This system is currently under development. For more information, see the project overview, timeline and motivation. My less-descriptive university page is found here.

Also, still not dead. But I have some new pretty videos - hopefully I can toss up the most recent ones (from last week) soon.

Daily Scrum

(Ideally updated somewhere between 10 am and 11 am)

Twenty-two (22) items left to address in the paper edits. Some involve creating figures. Lets see how quickly we can knock them off and move onto the next exciting paper!

Yesterday: (Last two weeks). Struggled wtih this website. It seems PmWiki has updated likely broken the use of Blog-It for posting. (Issues with formatting, and unable to associate with the blog it groups - via missing post controls).

Took time to go over Faramarz's feedback from the draft document of last fall. There are a lot of things that will need to be re-worked in whatever form it takes next. Started part-time work, and had bereavement issues last week.

Aliasing Issues

No Aliasing Issues!

(Yesterday) Finally worked out the issues causing aliasing on my in-house examples when loaded into SiftFu. Wasn't creating the depth files correctly. They appear to be accurate now, and generate better images. The stationary parts of the scene are not as smooth as desired, but this may be due to the dynamic nature of the in-house examples.

Today: Look at incorporating rigid feature labels for constructing volumetric representation in SiftFu. Visualize the results of this for the different groupings selected. Will need to look at extracting codebase from Matlab, or incorporating a GPU implementation for speed ups (its is awfully slow); as well as RGB colouring of results. Read more...

Yesterday: (Last term and a half). Was tasked with formally writing up the unsuccessful results mid-summer. Summer vacation. Continued writing through the fall, submitting a starter-draft midway through. Numerous suggestions for revisions, though the dominate question is what specifically should be described. Requiring better results before an improved iteration. Reached out (December) to researcher Barnes in Australia who has had success with similar work through student Perera, but have yet to hear back on possible collaborations, discussion or testing validation.

Was a sessional instructor for CPSC453 - Introduction to Computer Graphics during Fall 2015, managing 3 TAs and 75 students. While an amazing opportunity and incredibly motivating and inspiring for computer graphics, it was very time consuming (attempting to teach well, organizing and creating lecture material, re-working existing materials, organizing and updating assignments, creating and grading exams).

Today: (And last couple of days) After winter break, have been re-visiting where I am in the code base, and what needs to be updated/corrected to improve results. Overall todos:

  • Improving visuals through KinFu integration - variant of Barnes/Perera's 2014 work
  • Supporting NaN values for feature points (ie. spatially or temporally occluded) - consider modern tracking methods?
  • Improve speeds (GPU, parallelization, use of transformations, dynamic/adaptive feature tracking based on success/structure?)
  • Joint network determination
  • Improved test cases

I've taken on a temporary part-time contract with a great software company downtown for the coming term. An artificial deadline for April has been set for evaluation of PhD progress for future directions.Read more...
