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
