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