Programs will use: VDXM5, OCR-OSC, OSC-WEB
Using a couple programs that are downloadable and easy to use (they have desktop icons and everything), you can create your own OCR (text recognition) program!
Step 1:
Download and Install this program called VDXM5, (Or any program that can send video through a syphon as OCR communication)
Step 2:
Download and Install this program called OCR-OSC. These programs were created by a very cool person named David Lublin. He has made some great projects including this one!
Step 3***:
Go to https://github.com/automata/osc-web and follow the directions for install and usage: for your enjoyment and terminal ease - here is a picture of what to do (if you have git and npm package manager installed on your machine)!
(***This step is optional, but if you want to see your collected data in your terminal, do this! Also why not do it anyway! it doesn’t take long.)
~And I quote, “The objective of osc-web is to make possible to send and receive OSC messages on the Web browser.”~ This is very useful for all sorts of cool things.
Step(‘s) 4 (Set up of all components): NOTE: If you want to just watch a video walkthrough, click here --->
Open VDXM5 and make a new project (file --> new)
Drag your video into your media bin
Go to “Plugin” and select “Syphon Output” and select “Main OutPut”
Click “Layers” and find the “Crop” button - use the cropping feature to find your desired text, in the case of the attached demo, it is the ticker at the bottom of the hyper relevant cnn video.
After your video is cropped, Open OCR-OSC
Go back to VDXM5 and go to file → preferences → OSC
Click out “Output Ports” and make sure you have something that looks like this:
Go back to OCR-OSC and click the drop down menu - you should be able to select “VDMX5 - Main Output”
It should be streaming the video from VDMX5 when you select the correct source
Now what if we want information in our terminal?
Go to terminal and change your directory to osc-web (command is most likely [ cd osc-web ]
But wait, no information? Where is it?
Go to you osc-web folder and find the web-side folder and click on app.html
But wait? Still no information? Go to preferences in OCR-OSC and change your port directed at 3333
You should now be set up and watching your very own OCR (text recognition) program!
Let me know if you need more info!!!
Thanks to all the awesome software that @DavidLublin makes and the awesome people who came to TextAV!
