Expressions Data in FRGC 2.0 (3-D)

I recently needed to gather 3-D data of different people’s faces, in order to perform experiments on these and test new algorithms that I had developed. The problem was, without some metadata regarding expressions, how might I find correct pairs suiting a particular criterion/ia? Two universities that I contacted had some data of this kind, but they were unwilling to share it (Open Data principles betrayed). So I had to do it myself using a dataset I mentioned here before [1, 2]. So far I have covered smiles and since it takes a lot of time to achieve this, I would like to share my work with those pursuing similar data.

To proactively remove allegations of the set being too easy to deal with (picky-ness in peer review), the most difficult partition when it comes to acquisition quality is taken. The figure below shows some examples of pairs that are being used after being selected as not many images contain expression variation. The selection process of very tedious as very few 3-D images exist with expressions in them, especially ones from the same person (required for consistent training assuming intra-subject residues are alike for common expressions).

Face expressions
Examples of the faces used tor training and recognition, with neutrals on the left and smiles on the right (note: this is just the texture of 3-D images)

About 5 hours were spent classifying the NIST datasets for future experiments. An initial subset of it is put in loader files. From the whole 3-D data of the Face Recognition Grand Challenge, one can only find a few hundreds of distinct individuals. Not all of them have an acquisition with a smile. I found just over 80 by manually browsing everything and some will be hard to work with due to obvious cases of degraded signal. The criteria was that all parts of the face (mouth upwards) must be visible and the expression one of happiness, not necessarily a smile.

The program works reasonably well (see the figure below) with new implementations of ICP (there are two main ones from my research group) and the new data which comprises 86 pairs, or 172 images in total.

Expressions data

Examples of the program with the new data and methods in place

Here is the statement for loading the pairs of expressions in GNU Octave or in MATLAB, in case someone needs a large pile of gigabytes of consistent expressions data.

Later on I am going to publish all the code and about 100 pages of text. It needs tidying up first.

Goodbye, Skype

Skynet

I was never a major user of Skype. Heck, I only started using it on occasions around 2008, after I had repeatedly rejected invitations to join it. The reasons were multiple, e.g.:

  • It was non-standard (the protocols)
  • It was proprietary (it still is, but they openwash it for PR purposes)
  • It sucked on GNU/Linux
  • (Questionable: It offered no real privacy through decentralisation)

Now I have a fourth reason to abandon it altogether and move back to SIP, which sadly enough not many people are using as network effect matters. Microsoft has a very poor track record when it comes to privacy, retaining GNU/Linux support when acquiring software, and generally speaking, Microsoft is a convicted monopolist which continues to engage in crimes such as racketeering, bribery, and extreme market distortion.

Thank you, Skype. It was good while it lasted. And thank you, Microsoft, for giving me a reason to abandon this piece of malicious software and also encourage others to do the same, obviously to come over to SIP. Today I had a half-hour conversation over SIP (the codec is as good if not better than Skype’s). I also have a physical SIP phone connected to my hub. The future is SIP. Skype is going down the same path as Hotmail.

He also hangs out in the Techrights IRC channels, so please consider popping in to say “hi”.

TechBytes Video Episode #1 in Sound Only

TechBytes

Direct download as Ogg (0:58:29, 11.1 MB) | High-quality MP3 (20.3 MB)

Summary: An audio-only version of yesterday’s episode, hopefully with future recurrence of such a version for video shows

Yesterday’s [cref 48069 video episode] suffered some audio encoding issues, which led to loss of some information. It seemed reasonable to reach out for the audio dump and then put together the 3 parts with songs in between. The songs chosen for this episode are, in order of appearance, “Edge of My Seat” by Amber Rubarth, “Have This Drink” by Black Mike and Kemistry, and “Joyful Noise” by Breakestra (all from SXSW 2010).

“Thanks to the listeners/readers/viewers who provided advice and invited people to be guests.”The plan is, in general, to invite more guests to the show (like we originally did) and make that the key series of audio shows. Combinations/hybrids of audio and video can be put together separately and more quickly (less scheduling with guests along with other preparation are required), although we are still trying to resolve some technical difficulties with these. Thanks to the listeners/readers/viewers who provided advice and invited people to be guests. We have many in line now. One is scheduled for recording tonight.

First Episode of TechBytes Video


Summary: TechBytes video debugging and special coverage about SeaMonkey, the extensive software suite; we also cover Minecraft and few other topics

THIS is still somewhat of a prototype, but it is also our first episode of TechBytes Video, which required us getting a lot of technical difficulties resolved. The content was not coordinated and we hope people enjoy it nonetheless. We ought to stress that the audio show will continue separately as usual (this weekend, however, is a special one because of the Royal Wedding and Bank Holiday). We will produce audio shows at least once a week as visual element is not needed for a lot of the issues we cover, such as copyrights, patents, and songs that are freely (and legally) shareable.

Bytenotes: unusually, since we were still working on technical matters rather than anything like content for the show (it is not scripted or prepared really), just before recording the first episode of their new show Roy and Tim were experimenting with video as they attempted to debug an audio-video synchronisation issue, as well as screen size issues. The tests involved us going through SeaMonkey as proof of concept.

Summary: Rockstar Jono Bacon joins Tim and Roy to speak about the new Ubuntu release, his awesome band, and some interesting life ambitions

Jono BaconThis is the first among many shows where we attempt to get back into having guests, preferably different ones at each show. We are very pleased to have Jono Bacon with us today. We added a section about news to start off this show, so the section where we speak with Jono starts after 31 minutes. We apologise for some recording issues (mostly volume-related imbalances, which we tried to mitigate manually with limited success).

“Color” by April Smith (SXSW 2010 Showcasing Artists) and “End of Days” by Jono Bacon’s band are the tracks which we put in today’s show. We hope you will join us for future shows and consider subscribing to the show via the RSS feed. You can also visit our archives for past shows.
