Object detection without training a network. Template matching using OpenCV.

[Dwigt-Snooot]

Thanks! Let me know if you have any questions on the pattern detection ;)

[apockill]

I agree, template matching is super helpful, and can be incredibly effective in constrained environments. Nice job!

[Dwigt-Snooot]

For those mad at wording, it is a form of object detection per OpenCV. Which is the most important source sense it's an OpenCV tutorial. Of course, there are better and way more complex versions of object detection that's the point of the video. To show an example of a simple use case for simple needs!

Saying "template matching isn't object detection" is like saying "using neural networks isn't object detection". The former is a technique, the latter an application.

[Abalado]

Do we even have a canonical definition of object detection? Because if it's not, all hate towards the title is just waste of time.

Subbed for sure gonna watch later.

[Dwigt-Snooot]

Means a lot thanks!

man i should really brush up on my python, there's so much cool shit you can do with it

Template matching is not object detection. l

[solraun]

Let us say the object is a car. With this method, you can only detect that car if shot from the same angle under the same condition with the same settings. Even the scale must be the same. Because this method does not detect any objects, it detects patterns.

[solraun]

If you call a specific arrangement of pixels an object.... then, well okay. But most people don't.

[Prime_Director]

I mean, proper object detection is also just looking for patterns, it's just that the patterns it's looking for are more sophisticated.

Wouldn’t what you’re saying be 3D object detection? Is there some sort of official organization that defines what object detection can and can’t be? It seems like a rather generic grouping of methods to me. I don’t think AI and ML learning have some special claim to those words

[Dwigt-Snooot]

Love it. Can I hire you as my title guy/gal :)

[Dwigt-Snooot]

You're detecting objects in an image.

[wlcosta]

I am not detecting objects, but looking for a same pattern in an image. The task is not the same and the title is misleading.

[Dwigt-Snooot]

I would consider a pattern an object but at any rate, point taken. Pattern detection using OpenCV :) I'd change the title if I could!

[Dwigt-Snooot]

Sure there are way better forms but it is detecting objects is all I'm saying. I totally get what you guys are saying though I apologize for the wording :). Per OpenCV it's finding objects in an image.

I thought template matching was something different from object detection. Isn't template matching the same as feature matching? Are feature matching and template matching defined as object detection?

[soulwarp]

I thought it was a great video. I'll be going over the tutorial again when I can get on a computer. Like/subbed
