Really loving the latest content (in my best Matthew Berman voice) “Bravo” 👏 😁 this is phenomenal thank you 🙏🏽

I still want to hook up a camera to an actuator on my sliding door that will open and close it for my 2 dalmatians, but I want it to regocnise them and not just any dog etc. This is a good step in that direction

Matthew, can you make a video or point me to one you made on the conversion of image to embeddings? What does the data structure look like, what is algorithm.

In previous video you asked what we would like to see with autogenstudio. How about adding this as a skill to the agents.

imgbeddings has been trained on squared images only, I do not see in your code anything that create a square image from the face recognition output from cascade. it is a nice idea to use imagebeddings with a vectorial DB. nice job!

well, it would be interristing if you do the search for the same dude, but without a beard, with hat, etc... i don't think by just simply creating embeddings this could be done anyways. Actully this app has been around for decades, but with facial recognition technology (this is how the FBI and governments finds people), but their app works by measuring distances on the face and doing face recognitions techniques, it could find the person even if he has a different look.

It would seem that one could employ more complex metric for computing those distances where the distance is a function of tree node distance of some sort of ontology tree. Thus if one has a tree with two branches, say Sam (1.1) and John (1.2) and another tree that has food and under that pizza (2.1) and pie (2.2) and then another tree that has food (3.) and movies (3.2) and another tree loves(4.1.1), likes (4.1.2) , eats (4.2.1), and cooks (4.2.2) then we compare the sentences 1. Sam (1.1) loves (4.1.1) movies (4. 2.1), 2. Sam (1.1) loves (4.1.1) pizza (2.1) 3. John (1.2) likes (4.1.2) pie (2.2) 4. John (1.2) eats (4.2.1) pie (2.2) 5. John (1.2) cooks (4.2.2) pizza (2.1) where the distances are the number of nodes between two nodes such that 1.1 is one away from 1.2 where 1.1 would be two away from 2.1 (1.0 to 2.1) etc. One then can compute distances based on these and get more nuanced matches. I imagine there is name for this type of distance metric but am not sure what that name might be. Also, that might be sort of what neural nets do with their weights is model such metrics.

what's the benefit of using postgreSql vectorDb vs chromadb?

Great Video

Super ! Thx

kinda stuck. Whenever I run the first block of code, it only detects one face in the image. Not multiple.

Hello! If it's possible, could you explain how to extract faces to identify from a webcam in the final phase, instead of a given photo? Please reply

Hey I’m just wondering if i could get a rating of match probability, you know, to understand how much they look alike a face to another face?

"Easy" they said... 😅

hi, instead of vector in postgres what datatype to use in mysql ?

How would I run this locally? I have postgres installed on ubuntu 22 but I can not find any postgres extension named vector.

yeah i rather just have my db locally... not a big deal if it's public faces, but for an actual application it's risky if i don't know where that data ends up at (which data center, which service there, who maintains it, ...) because data breaches are a thing - if that's customer faces (data) and that is associated with names and correlated demographics data, if the db(s) get hacked... can you say "lawsuit" and "jail time" possibly. i know i'm not taking the risk.

Most problem is lagging video in webcam, rtmp when face recognition running in opencv. u got idea?

File "c:\Users\kyubi\Programming\embedding.py", line 15, in img = Image.open("stored-faces/" + filename) ^^^^^^^^^^ AttributeError: type object 'Image' has no attribute 'open' Does anyone know how to fix this error?

...again the code which is not working offline. Works until provider close or change server . No thanks ...

Do you know about ways to plug this in to CCTV cameras? I’d like to use it to create logs of arrivals and departures of my staff

The way croissant was pronounced triggered me a bit. But interesting tutorial, keep it up

Да и каскады хаар очень старая и неточная

But if I program facial recognition software and put it in the countryside, will it recognize the wild boars one by one? 🐗🤔

You Forget to test with a wrong face (an unknown person)

It may have trouble recognizing faces that are not mostly vertical.

Society is taking a huge step into the future. AGI and people with "ANY SOFTWARE" capabilities. AGI will be here this year.
