A Single-Pixel Camera Without Moving Parts Using Compressed Sensing

There’s a strange allure to single-pixel cameras due to the simultaneous simplicity and yet fascinating features that they can offer, such as no set resolution limit. That said, the typical implementations that use some kind of scanning (MEMS) mirror or similar approach suffer from various issues even when you’re photographing a perfectly stationary and static scene due to their complex mechanical nature. Yet there’s a way around this, involving a LED matrix and a single photoresistor, as covered by [Jon Bumstead] in an article with accompanying video.

As he points out, this isn’t a new concept, with research papers cited that go back many years. At the core lies the signal processing technique called compressed sensing, which is incidentally also used with computed tomography (CT) and magnetic resonance imaging (MRI) scanners. Compressed sensing enables the reconstruction of a signal from a series of samples, by using existing knowledge of the signal.

In the case of this single-pixel camera, the known information is the illumination, which is a Hadamard matrix pattern displayed on the 64 x 64 pixel LED matrix, ergo 4,096 possible patterns. A total of 4,096 samples are thus recorded, which are subsequently processed with a Matlab script. As pointed out, even 50% of the maximum possible matrices can suffice here, with appropriately chosen patterns.

While not an incredibly fast method, it is fully solid-state, can be adapted to use other wavelengths, and with some tweaking of the used components probably could cut down the sampling time required.

We've improved how we direct connections to GrapheneOS servers by using anycast to fill in missing GeoIP data. This should reduce service latency and improve download bandwidth for many users in the western US and especially with certain VPN providers.

Here's an example of how we use anycast to send traffic to the nearest nameserver:

ping.pe/ns1.grapheneos.org

This shows how we respond with an IP address based on GeoIP + anycast node:

dig.ping.pe/grapheneos.org:A:n…

With these examples, only 1 is off (UK server geolocated in US).

in reply to GrapheneOS

You can compare those to see that does a great job:

ping.pe/51.222.156.101
ping.pe/209.141.35.164
ping.pe/54.37.41.188
ping.pe/51.79.160.50

Note ping.pe looks up a domain name in 1 location, then pings it everywhere, so it's misleading for a domain.

in reply to GrapheneOS

Improving update download speed is the biggest benefit. One of the network services we provide to GrapheneOS users is secure network time where low latency improves accuracy. See grapheneos.org/faq#default-con…, grapheneos.org/faq#other-conne… and grapheneos.org/features#networ… for the other services.
in reply to GrapheneOS

The way we've set up our server infrastructure means that any single provider having downtime won't take down our website, updates or network services. We can scale it up across providers instead of a specific one. It's also extremely cost effective to save money for development.
in reply to GrapheneOS

Please add alternative options for timekeeping, as it is critical for Internet access and TOTP. If ever grapheneos's servers have issues, there is no easy way to get accurate time.

@kurtz We improved it for everyone around the world. We're only saying that the biggest improvement is for the western US. That's because directing traffic with GeoDNS in the US to each coast relies on GeoIP data having a state but it often only has a country. We use the free GeoLite2 database from MaxMind instead of their paid GeoIP2 database with more city/state data.

It also helps with VPN providers using servers without GeoIP data available. Server provider GeoIP is worse than residential.

Did you know that if you keep a pet moth and need to feed it sugar water in a dish, the moth will not drink unless you help it by unrolling it's proboscis into the sugar water? Here is a moth having a little tantrum as it's keeper tries to get it positioned to feed. Obviously this is a very delicate procedure, and I'm impressed with how gentle she is.

Once our fussy boy tastes the sugar the tantrum instantly stops and he just drinks deep.

The image shows a computer screen displaying a terminal window with various data and graphs. The terminal window is divided into several sections. On the left side, there is a list of games with their respective white and black accuracy percentages, along with a progress indicator showing "progress: 29/1853." The list includes game names such as "clusterable_games_classical" and "games_classical," with accuracy percentages ranging from 64.8% to 95.9%.

The top right section of the screen shows a CPU usage graph with temperature readings for different cores, indicating temperatures ranging from 65°C to 78°C. Below the graph, there is a section labeled "disks" with details about total, used, available, and free disk space, as well as cache and swap information.

The bottom right section displays a list of processes with their CPU and memory usage, including programs like "Stockfish," "Spotify," and "IpdalWire." The system information at the top of the screen shows the time as "08:05:14" and the date as "Tue May 13," with a battery level of "99% 6.800V" and a total of "2000us." The terminal also shows the command prompt "zsh" and the current directory "/Users/zsh/".
