Hi, I'm new to opencv and i'm trying use opencv to detect fire hydrants and rail signals. I have extracted a firehydrant picture from a video and use surf to detect the picture in the same video. The sample example was able to detect the hydrant. However, when i try to detect the hydrant on another video it failed to detect.

I would like to know what detector i need to use. Please note that i'll be adding some more objects to detect such as rail signals, rail cross etc.

Can anyone advice me what I need to do

Thanks Aswin Paranji

Could you post example images of the object you need to detect and on which backgrounds? The question is a bit unclear

Basically cascade classification is all you need! Check this and this. Do a search on the forum, I think there are about 2000 topics on object detection using this technique!
