11.6: Computer Vision: Motion Detection - Processing Tutorial

In this computer vision tutorial, I show how to analyze the pixels of a video to detect motion. This technique is also known as frame differencing.

Send me your questions and coding challenges!

I thought I would really choke on this one because it seemed hard for me to comprehend but after checking the video twice and really focusing in, I got it. You really did such an amazing job on this one. I really appreciate what you do .Even after 2 years your learning people. Seriously! Best teacher man!!!

This is a best lesson I've ever seen.

LOL the funniest programming course ever, it proves that the line between genius and madness is very narrow

Dude coders are allowed to have fun, our brains would catch on fire if we couldn't have a laugh while working :D

Hey just wondering if there is a source code for this series. Coding train on GitHub only has 1-9 : (

So funny when you dance :D I understand why no people disliked that video, it's soooo cool !! Great Job !

[naraendrareddy]

Now I have a question. We have detected the objects. But how do we calculate the velocity of the objects if we want to?

Hey man, you ruin my imaginations of adobe programmers skills :D It seems to me that adobe master collection should be done in a week !!

I tripple hit the like button when you started dancing xD keep it up

Hey at 11.12 sec there you have done betterjob. So I a have an idea about, can you make a program for that exactly 3d virtual frame( fix your face then when you giving input as your face to webcam when it matches to your frame as you did at 11.12, then only it has to take the image ) so can you do that.
Or tell me where I can get that exactly. Please. Thank you

hello, since I met your channel (6 hours ago) I'm learning twice in college! I can not stop watching and wanting to know more. how do you explain is understandable, although I do not speak your language (I'm writing this on google translator).

I have a question for you:
manages to capture the moviento of a beam of light with background subtraction. but I need to replace the entire motion detected by figures (ellipses) to emulate the movement of light (infrared light) in a more visually appealing way. the violet ellipse ellipse (lerpX, lerpY, 36, 36); It is a single figure, following a movement.
as I can make every pixel in moviento be replaced by hundreds of ellipses?


Thank you!!

As always, thank you so much for creating such helpful content.
I was trying to find the code from this lesson on GitHub, but didn't see it - does it exist anywhere else?
Thanks in advance!

[bryphi]

I finally have something of value to comment... yay!!!
This works better if the loop is placed in the capture/movie event.

Dan... You are the emperor of teaching. This series in particular has been so helpful to me. I have tried to implement a nearest point algorithm in the past and failed, but I was easily able to fallow along and actually learn and understand well the process. Thanks so so so so so much...

Where do I find the p5.js version of this?

[bazaci]

All these videos are so helpful and fun. Thanks .

[audreyli]

Thank you for bringing so much fun to the lessons!

i try to track white pixel in a image, when the pixel moves, it merge with non moving white pixels.. how can i seperate moving and non moving pixel in a image using opencv c++

[guruteja]

Is there a way to find out if a user is talking with in a image frames of video, I mean with out audio??

[Ejotei]

can someome help me please?! I need to make a processing file that increases the volume of a track by detecting motion from a webcam, I'm very new to all of this and managed to get the webcam and track working however I have no clue on how to get it to change volume based on motion.
