Hey StevenPuttemans - firstly sorry for this late reply. Will I need to convert my signs into marker form? Or are these markers 'set' already? Also do you know here I can find a good tutorial so I can have a good stab at this? Thanks in advance

Hey @StevenPuttemans - Thanks for the speedy reply! I've just had a little look into Aruco markers. How robust would you say this is against false detections? With my current signs I've tried an approach with just detecting squares but got a lot of false detections! I think this marker detection thing might be more reliable?

@StevenPuttemans - I'll try to be as specific as possible - I'm working on a Robot using OpenCV that reacts to signs (Go, stop, Turn left, Turn Right, 360 turn, etc). So when the robot "reads" one of these signs it will know: a) what the sign is and b) what method to execute. My problem is I'm not entirely sure how to get the Robot to recognise signs via a camera - I've tried multi-scale template with no success (I was told that multi-scale template matching would be best for a project like this).

I guess what I'm trying to do is template matching an image via a camera. So I will scan an image of a game's cover and the output will be the name of the game. image of game

my question is what would be the best way to detect a certain image (so like a sign) via a camera and to draw a rectangle around it once it has found it

Hey guys, I wanted to ask which methods would be ideal for finding a certain image via a camera. I started OpenCV 2 weeks ago so am still relatively new to this but have looked into using Multi-scale Template matching with little success. The code that I have been fiddling with comes from this website link text

Any help would be greatly appreciated, thanks!
