Hi there guys. I am starting a project which needs to have real time video recognition. I was thinking of utilizing Matlab for that but, receiving the video from a camera module connected to the arduino. What I have been struggling with is to connect a camera to the arduino. I currently own a 600TVL like this one, but I'm not sure if this module is possible for what I intend to do.
Do you have any suggestions of what to do? Do I need an SD card as I have read? What camera module and driver would I need to acquire to successfully get the video to Matlab?
Thank you very much.
I suggest using a RaspberryPi3 instead of an Arduino

// Version 1.0 (Release) June 3rd 2011 by Carlos Agell (MoviMED) //
// Arduino code based on the example by Michael Krumpus //
// at Nootropic Design. //
// The software dynamically changes the threshold for the analog //
// video acquisition taking advantage of an R2R ladder. As soon as //
// a serial character is received the arduino starts acquisition and //
// sending process over serial. The serial counterpart needs to put //
// together the image by adding all the images and scaling to 255. //
// //
// See LabVIEW counterpart. Processing counterpart will be coded soon //
// //
// TO DO: Improve speed on sending by packing bytes into hex codes //
// it currently sends a single bit per byte. //

I don't think an Arduino has anything near the processing power needed to do video recognition. A Pi may be pushing it already.

Your requirements contradict themselves. You want realtime video recognition, what ever that is, at the same time your want to move a frame of video data from device to device that may take days.
