Hi Zhijie! Thanks for clarification! Still though it is interesting what the community thinks about such sort of apps. Does it worth putting an effort into it? Again referring to my previous experience would be interesting / cool to have an

Hi, due to my experiences on VideoMapping I'm a bit critical if this would work on our amateur scenario. I have no clue about image processing but noticed that even for Humans it can be hard to find all signs along a street. But anyway, we will only know if it works, if somebody tries :D Mat

Having a quick look on google scholar shows that there actually appears to be quite a large set of research literature on exactly this problem. I.e. How to detect traffic signs in real time from a front facing vehicle camera. I guess it isn't too surprising given that driver assistant systems appe

Hi everyone, I think I need to make some clarification here. Actually, in the past two days, some students who want to participant in GSoC sent email to me to show their interest in the idea "Develop a Simple Mapping Tool for Mobile Phones". I'm sorry to not have reply immediately. Here I must cla

Hi, great to see that someone is interested in the project idea and I'll be interested to see the proposal draft. There are a number of standard object detection algorithms that should be able to detect speed limit signs on a frame by frame basis in real time. Once a sign is located in the image,
