0:00 - 0:06Module 10.3, examples of start-ups that
use signal processing as a core -
0:06 - 0:10technology.
Earlier on in this class somebody asked -
0:10 - 0:13in the forum, if I follow digital signal
processing class, can I get a job in the -
0:13 - 0:18start-up and what sort of start-ups?
So this brought us to think, well maybe -
0:18 - 0:24we can describe a few start-ups that came
out of research done in the lab. -
0:24 - 0:28And our four that we discuss here, there
are actually more that are active, but -
0:28 - 0:32four will be discussed here are
Illusonic, Quividi, Sensorscope and -
0:32 - 0:37Vidinoti.
So the first start up I want to discuss -
0:37 - 0:40is called Illusonic.
It was started by Cristof Faller who did -
0:40 - 0:44his PhD thesis on a time as a
[INAUDIBLE], and was interested in -
0:44 - 0:51acoustical signal processing.
And in particular in multi channel audio. -
0:51 - 0:54So if you do acoustical signal
processing, there are questions like -
0:54 - 0:58beamforming, echo control, we just
discussed this earlier. -
0:58 - 0:59We used a project of can you hear, the
shape of a room. -
0:59 - 1:04When you want to do spatial audio
processing, you want to generate audio -
1:04 - 1:09for many channels.
Either for headphones or for multichannel -
1:09 - 1:14loudspeaker systems, you may want to do
upmix or you take a stereo signal and you -
1:14 - 1:20would like to render it as a 5:1 signal
or as a 17:1 signal. -
1:20 - 1:26And, there are tools, of course, where,
you can use signal processing techniques, -
1:26 - 1:33for example, to de-noise Music or
de-reverb, recording of, person singing. -
1:34 - 1:38So the tools that are used at Illusonic
are classic digital signal processing -
1:38 - 1:43tools, plus what was discussed briefly,
when I talk about the class on audio and -
1:43 - 1:49acoustic signal processing.
Again, perceptual models are extremely -
1:49 - 1:53important because the human auditory
system is a very sophisticated signal -
1:53 - 1:57processing device, and if you try to fool
that device you better need to understand -
1:57 - 2:04how it works.
Here is an example of cool application, -
2:04 - 2:09so let's say you have your home cinema
and you have a stereo recording that you -
2:09 - 2:16would like to listen to.
So the home cinema has actually in this -
2:16 - 2:21case one, two, three, four, five, six,
seven, eight, nine plus probably two base -
2:21 - 2:26booster somewhere, so it's probably an
eleven channel system, so you would do -
2:26 - 2:34enough mix from a stereo signal, let's
say from your MP3 player... -
2:34 - 2:38To this eleven channel spatial audio
system, and you would like to make it so -
2:38 - 2:42that it sounds really like you're in the
concert hall. -
2:42 - 2:45And so even sony has a very cool
technology to do this, and not only do -
2:45 - 2:48they have the technology, they actually
sell a box that will do this at -
2:48 - 2:55professional quality level.
So the company is it's a small company -
2:55 - 2:59about five people, half a dozen people,
it licenses technology, state of the art -
2:59 - 3:06stuff, to other, companies, and it has
custom technologies that it develops. -
3:06 - 3:10For specific applications and as I
mentioned it has this very cool Immersive -
3:10 - 3:14Audio Processor that was just launched
this year and please visit our website -
3:14 - 3:18and see this cool stuff and if you want
to buy one of these Immersive Audio -
3:18 - 3:25Processors, I can tell you it sounds
incredibly beautiful. -
3:27 - 3:29The next company I want to describe is
Quividi. -
3:29 - 3:33Now this is a very important company in
its class because its a company of Palo -
3:33 - 3:37Prandoni.
So when he's not teaching on Coursera and -
3:37 - 3:42playing his his guitar To explain signal
processing. -
3:42 - 3:46He's actually the CTO of a company in
Paris, called Quividi. -
3:46 - 3:50And Quividi does a full length thing in
environments where you have cameras and -
3:50 - 3:54you have digital signage.
So we have advertisements on screens or -
3:54 - 3:58you have information on screens, then
Quividi clearly allows you to monitor who -
3:58 - 4:01is actually watching what you are
showing. -
4:01 - 4:05So if you have a bunch of people in front
of this camera, it will identify also -
4:05 - 4:08people it will say oh, here is a lady,
here's ladies, you also got, a few of the -
4:08 - 4:13people are guys.
It will make some statistics, how long -
4:13 - 4:17the people actually watch for example in
advertisement, where they look on the -
4:17 - 4:22screen and so on.
And this entire system is distributed in -
4:22 - 4:26the cloud, and Allows you to do a
dashboard, a so-called dashboard, of how -
4:26 - 4:32your advertisement is being seen in these
public screens, or in the malls where the -
4:32 - 4:39screens are being shown.
And at latest, they have 150 networks of -
4:39 - 4:45measurements that are deployed all across
the world as you can see. -
4:45 - 4:51And there are some very famous names that
show up and so they essentially can do -
4:51 - 4:55monitoring of the quality of
advertisement for all of these companies -
4:55 - 5:00essentially in real time and provide
reports to the effectiveness of using -
5:00 - 5:09advertising on screens in public spaces.
Okay, that's the story of Quividi. -
5:09 - 5:12It's cool technology.
It uses computer vision, image -
5:12 - 5:15processing, the, it also uses a lot of,
you know, state of the art, algorithmic -
5:15 - 5:20and machine learning technology.
Please visit their website if you want to -
5:20 - 5:26know more about this one.
The third company is called Sensorscope. -
5:26 - 5:31It grew out of all the efforts of doing
environmental monitoring and various -
5:31 - 5:35projects here at DPFL.
So, if you want to do environmental -
5:35 - 5:38monitoring, it's cool if you can do real
time visualization of what is happening -
5:38 - 5:42there.
an application where people are very -
5:42 - 5:47interesting is so-called precision
agriculture, so we want to control the -
5:47 - 5:51quality, let's say for example, of water
systems. -
5:51 - 5:56you also want to detect you know, certain
weather patterns and so on and then -
5:56 - 6:01optimize crop production thanks to this
monitoring. -
6:02 - 6:06So the company does large scale sensor
networks, deployments and data -
6:06 - 6:10management.
So you need wireless sensor networks. -
6:10 - 6:14So these are small stations that talk to
each other in an ad hoc fashion. -
6:14 - 6:18So self organize sensor networks.
Then you need signal and image -
6:18 - 6:20processing.
The usual stuff that you have learned -
6:20 - 6:23here in the class.
And of course radio communication -
6:23 - 6:28technology.
So here would be a typical example. -
6:28 - 6:32you build a monitoring station.
We have seen such monitoring stations at -
6:32 - 6:37class when we have discussed sampling
issues with respect to rain monitoring. -
6:37 - 6:42So you take state-of-the-art,
off-the-shelf sophisticated monitoring -
6:42 - 6:46communication and so on.
You build sensor stations. -
6:46 - 6:50You deploy them in a self-organized
network. -
6:50 - 6:53Then from a bay station you talk to the
cloud. -
6:53 - 6:57On the cloud, you have all this data, and
people that are interested in monitoring -
6:57 - 7:00this sort of deployment get access,
privileged access to this data and can -
7:00 - 7:04take statistics and, you know, decide
what to do, for example, about their -
7:04 - 7:12precision agriculture project.
It's a small company, half a dozen -
7:12 - 7:16people, and probably its main market is
precision all, agriculture, even if it -
7:16 - 7:20started, also from a, academic point of
view, mostly about environmental -
7:20 - 7:25monitoring.
And you can watch their website here, you -
7:25 - 7:29can also watch all the data that is
online at climaps.com. -
7:29 - 7:33So all the deployments that have ever
been done by the company and by the lab -
7:33 - 7:38are actually available here on, on this
website, and you can also use this data -
7:38 - 7:42and you know, do some further signal
processing if you're actually interested -
7:42 - 7:50by this topic.
The fourth company here is called -
7:50 - 7:54Vidinoti.
It's a recent start up from the lab and -
7:54 - 7:57it works in augmented reality, in
particle augmented reality on mobile -
7:57 - 8:01devices.
So, the core technologies image -
8:01 - 8:06recognition, computer vision.
But in a ways that is robust and then to -
8:06 - 8:11also do all these processing in real time
on small devices, like mobile phones and -
8:11 - 8:15decide how much processing you do on a
mobile phone, how much you do in the -
8:15 - 8:23Cloud or on the server.
And Vidinoti has a bunch of state of the -
8:23 - 8:27art.
Algorithms on the one side, to do -
8:27 - 8:32tracking and recognition, and also a
number of cool ideas on how to do -
8:32 - 8:37augmented reality based on these
methodologies. -
8:41 - 8:44So, the technology is essentially
cloud-based. -
8:44 - 8:48But there is an iPhone application that
you can download, and then you can -
8:48 - 8:53annotate your favorite pictures or
newspapers or whatever with augmented -
8:53 - 8:58reality, and this is actually being used
in particular in the newspaper industry -
8:58 - 9:02to sort of bring digital content in a,
you know, in a funny or attractive way -
9:02 - 9:09onto a medium.
Mainly the newspaper that is being -
9:09 - 9:12challenged by, of course by Internet
currently. -
9:12 - 9:18It is a small company, less than 10
people currently. -
9:18 - 9:22It has you know, a strong research and
development. -
9:22 - 9:26It has also a strong intellectual
portfolio based on patterns that has been -
9:26 - 9:31generated over the year around Augmented
Reality. -
9:32 - 9:36And if you want to know more, here's a
web site, and here is interactive -
9:36 - 9:40application for the iPhone currently, it
will be ported to Android within a couple -
9:40 - 9:47of months as well.
So, these were example of start-ups that -
9:47 - 9:51used state of the art signal processing,
image processing, computer vision, and so -
9:51 - 9:56on.
And bring it to the real world, in very -
9:56 - 10:02concrete applications, from audio, to
sensor networks, to augmented reality, to -
10:02 - 10:08monitoring of audience in, advertising.
