hello i am trying to create a system which can image through walls. it will be processing a lot of video content. i am not sure which arduino board to purchase, or should i purchase a raspberry pi because of the video content. also if it would be necessary to purchase video shields to add to my arduino. thanks very much.
Please link to a video shield and we can comment on its suitability for your project.
how about this one. thanks. NTSC/PAL Video Display Shield - Arduino Project Hub
How do you plan to use it? Where will the video content come from? That board produces video, doesn't process it.
We need a better description than "images through walls" to understand your needs.
Oh come on. We do not need very many details to be able to say "Most Arduino boards are NOT SUITABLE for "processing a lot of video content." They don't have enough CPU power, and they don't have enough memory.
The new Portenta boards MIGHT be an exception - there is even a "Machine Vision Bundle" being sold from the Arduino store. And there are some ESP32 boards that do some fairly limited video (but not specifically Arduino boards.)
But in general, you'd be much better off with a Raspberry Pi board with CPU >1GHz and RAM > 512Mbytes...
Yes, but it might be more easily achievable than the previous project,
"I am implementing phase singularities in order to generate wormholes, and ultrabroadband invisibility cloaks on the arduino."
Is this from Silicon Chip?
the data will come from either an image sensor or antennas. the system will implement passive synthetic/real aperture imaging. found in radio telescope arrays, space telescopes, and satellite imaging.
So you have some sensor data you want the Arduino to detect, is that correct? And if the sensor data you receive meets some criteria, you want videos of some kind to play, is that also correct?
Do you have the Arduino detecting sensor data yet?
Would a Raspberry Pi be fast enough for your needs? How experienced are you with Raspberry Pi (and I don't mean flashing a Retropie image and playing games, but actually building projects with it)?
These and more are all good info that would get you help here more efficiently than the vague details you've provided, just for future reference.
To help get the ball rolling on the other hand, have you ever looked at [https://processing.org/] ?
If you have an old laptop lying around, Processing has a video library and you could connect some Arduino to the laptop and using chars or such as triggers to Processing, make video clips play in response.
To get that in another room (and I'll just say I know it works with Windows laptops because I've done it), you can set the laptop to never sleep or shut down or turn screen off while plugged in under Power Management, then plug a wireless HDMI transmitter/receiver kit into the HDMI out on the laptop to the monitor in the other room you need it. I bought a kit (it was about $130) from Amazon, it was plug and play, works great, no detectable latency. I did have to supply my own wall warts for each half though, they weren't included and it turns out the 3A, 5V ones sold with Raspberry Pi kits work perfectly.
thanks a lot for your responses. i am a beginner with not much experience in microcontrollers. i just wanted to find out which arduino/microcontroller would be suited for a system of this kind. yes, realtime image data will be received from a sensor or antenna and will be displayed as video after processing. the system would be able to image objects behind walls.
What IS your experience in? What KIND of data? Like, telemetry from coordinates? Light levels?
Your lack of detail is making this project sound way outside of anything "beginner" level, if I'm honest. It MIGHT be simpler than it sounds to me based on your cursory descriptions, but that's hard to know since you've not provided us with knowledge of where you are starting, ie what equipment you already have, what you've tried and maybe discussed with others elsewhere, that kind of thing.
I'm an amateur hobbyist, if you want to get and keep the eyes of the real gurus in this forum on your proposed idea, you'll have to go in depth as I've indicated and read this:

Good luck.
i will take a look at the implementation of imaging sonars, humminbird, lowrance, garmin using the arduino/raspberry pi and i will post if i have any questions. thanks a lot for your help.
