04.06.2021 manipulate webcam image by pixels

Please find here the patch: File:210604_Project.maxpat

I can't figure out how to create a new image / video from the edited cellblock (the edited pixels). Do you have a tutorial or references for that? I am wondering if a command which manipulates the whole image - not individual pixels - would be interesting. Probably that's why you recommended jit.gl.pix, but I can't make it work.

Here are some reference videos I found online

  • Creating Images with jit.matrix [2]
  • RGB Glitch Effect [3]

03.06.2021 sensor arrived / try and error

I connected the pulse sensor to Max and had some troubles on my way there.

As the sensor is sensitive to light, I came up with the idea to put it inside a box. I seems to make a difference, but I am not sure.

I used similar objects from the "sensing physical parameters" patch and an Arduino code I found online.

I have no clue how to connect the input from the sensor to the webcam image. I am searching online, but I haven’t found good references / tutorial how to distort a live image with specific data input. I would be very happy for any hint. During the research, I found the method of using the webcam as the tool to measure your heart rate. I think this would be way more interesting!!

What I am imagining right now, but don’t know where to start is the following: The visitor is coming closer to the screen, seeing itself inside the webcam. The pulse gets identified by the webcam and the human is recognized as well, (ideally turns red-ish; opacitiy 50%; maybe by using the cellblock object?) The pixels of the human stretches to the rhythm of the pulse.
