So Shortly before my proposal was submitted after consulting with my supervisor it was decided that a slight shift in focus would be necessary. Instead of pursuing an system for affect detection in audiences, a framework to solve some of the challenges in such a system has become the goal. the main reason for this is because affect detection is a field that is changing quite often and a problem that is very challenging to solve. Therefore there would be some value is developing a facial extraction framework with an inversion of control that would call a supplied method to classify or quantify the emotion in each face. This is the new direction for the thesis, and the core of the proposal.

Proposal time

This week I've been gathering together all my thoughts and ideas and trying to produce a cohesive document that outlines my plan. I keep finding new papers! that slows me down a fair bit. but almost done!

OpenCV and Visual studio

As Hamed has already begun using OpenCV2.2 I have decided to try it out, as i run visual studio on windows 7 x86_64,  i needed to build OpenCV from source as there weren't binaries available for this version and platform.

i followed this guide to get it set-up and there were a few hiccups along the way:

First they left out a step, after you build the whole solution, you need to build the "install" project to ensure the source and the libraries are assembled in the correct directories.

and second you have to set the build target to x64, however i think in hindsight as there is no "64bit" version of visual studio 2010, i could have used the 32bit version and just build for 32bit. but given that i had it working i decided for the time being just to stick with x64.

OpenCV is great, it  has lots of functionality that will save a fare amount of time. however the video formats and codecs it supports are quite limmited, see

unfortunately the video i had recorded at the end of last year is in a format that is not supported, despite the fact i recorded with a kinect, this is because i used the open source drivers to record as such i will have to re encode, or make a new recording using the official SDK, Hamed kindly linked me to his code that he used to make recordings,

also of late, i have been working on my proposal which is due on the 14th of April!

Made a recording!

I did a sample recording late last year so i would have somthing to work with, it should prove usefull, there was only about 4 people in frame, but for now it is more than sufficient. I had hoped not to tell the audience they were being recorded untill after so as to ensure their reactions would be natural, but it ended up nececary to inform them, they were all willing participants.

Also, I am begginig to think I will have to end up using the Official SDK, the open one does not yet support the microphones in any capacity, even recording audio. which will be an issue.
