11.10: Computer Vision: Adding Lifespan to Blobs – Processing Tutorial

In this Computer Vision tutorial, I enhance the blob detection algorithm with blob “lifespan.” This allows me to track a specific blob even if the vision algorithm fails to detect the blob (or if it exits the window) for a brief moment.

    I have see all your videos on Computer Vision and did not see any thing on shape or letter recognition. Would you consider doing a tutorial on recognition or could you please point me in the direction of where I would find this information.

    Wouldn't this series be a nice one to implement machine learning?

    your videos are the best, keep going! you could try to do something with the blob like moving the mouse or with a specific blob move start a countdown timer at take a picture from the webcam for example.

    Daniel Shiffman, did you notice that your face was a blob?

    i made it to the end. i have alot of thoughts, not really prudent to place them here, but thx. i learned alot, and not really about coding itself, but learning that with a processor, you can dissect the world around you. a great gift. ((and a great weapon)against no one but the mean aliens lol)
    great work my friend.

    Yow! we bore down even more! Just like REAL code gets developed.

    Very few people code on the fly and pull it off. Even when you make mistakes, you explain them. .. which is as important as being correct in the first place. You are teaching people to code like no one else I have run into on YouTube.

    keep er up!

    You need to reset the counter in case 1 and 2 as well.
