how to detect speed breaker in a road using matlab?

Why do you want to know? Are you working on intelligent vehicle vision systems or something? Just curious...because you seem to work on an incredibly wide variety of projects, from gait to speech to neural networks to gender identification to rain drop detection to filter design to crowd estimation (head counting) to face recognition to video analysis to color segmentation to facial expression identification to 3D imaging to license plate recognition to genetic algorithms to OCR to Simulink to medical imaging to....... And that's all within the last year. Truly impressive. You're approaching the number of different projects I work on in a year.

I love working with MATLAB. Its very very nice to work with it. Incredible tool. has lot of options in many domains...Moreover I get online support from you, walter, simon and many more matlab experts. Thanks to all of them. I develop projects for students. Thatsy I work in all toolbox which use MATLAB.

[Image Analyst]

Ah, so you're a MATLAB instructor, that explains the wide variety of subject matter.

[Sivakumaran Chandrasekaran]

I conduct MATLAB workshops in various engineering colleges as well develop projects for students.

It depends on the implementation of the speed breaker. Then can be knobs of less than a centimeter in the pavement, a bump over street of 10 centimeters, road signs, a display showing the current speed.

To consider all of them efficiently with a low error rate I suggest the following: Buy a commercial Matlab version, ask a student to sit on the passenger seat, offer Matlab as payment when the student mentions all speed breakers.

I'm not kidding. I'm physicist and this is seriously the best answer yet. When you want something more technical, please define the problem with any details. But I claim, that it is not useful from a global point of view to bother Matlab, when the job is trivial for humen. A two year old child will be better than the most intelligent Matlab program.

... and then there are the reduced speed limits that only apply during school hours, and the reduced speed limits that only apply when construction workers are working. And if there is a bus stopped with its red lights flashing then you have to stop (speed limit 0) if you are going in the same direction, and sometimes you have to stop if you are going in the other direction (but not if it is divided highway.)

Thanks for your reply...Please check this link and suggest me

That's not a speed breaker in a road. That one would be super super trivial to find - simply threshold at anything less than 255!

[Walter Roberson]

We would call that a "speed bump".

[Image Analyst]

I would also call it a speed bump. I've heard in some areas they call it a "sleeping policeman". At least they do in Jamaica and I was wondering if they did in all ex British colonies. I was confused when I saw signs at a resort there saying "Watch out for sleeping policemen." I had to ask what that meant!

[Sivakumaran Chandrasekaran]

so thresholding does everything..got it.. thanks

[Walter Roberson]

The comment about thresholding had to do with the fact that there is no road in that image, so if you throw away the white background you get the speed bump.

I'm convinced that a wasp on the camera will confuse the recognition efficiently, such that any automatic reaction will reduce the security in the traffic. Everything which encourages the driver to take a nap instead of beeing as concious as possible is nothing I would like to support.

[Walter Roberson]

Detection of a speed bump could be important for automated driving (such as being actively researched by Google.)

[ali elnaggar]

please code and information "measure car speed">>>>>>>>> thinks

[Paul Udah]

please is there a code for detecting speed bumps using hog techniques in matlab
