i need some help for the method that i should use in the car park vacancy detection using static image..

i already try many method such as background subtraction,edge detection and so on.. but as you should know,i am new in this matlab world.. and i really need help from all of you because this is my final year project.. hope that the community can help me...thank you

Please expand on what your task is. It appears at the moment that you have to figure out which parking spots in a parking lot are empty? If so then what are your inputs, and do you have multiple cameras so as to be able to work around all the "blind spots" caused by large vehicles making it not possible to see whether a parking spot behind them is empty or not?

What papers have you read regarding this subject? There must be a number of documented algorithms out there.

I would instinctively try for something that works on a combination of chroma (if images are colour), some kind of uniformity measure, background subtraction, and edge strength.

You need to supply more information. Are you working off stills, or a video stream? How frequently do you receive frame updates? Are the cameras static, or panning? Do you know the positions of the carparks? Is lighting reasonably consistent? Are the images colour or monochrome? How many parks fit in a frame, and what is the image resolution?

If you receive help from this forum, don't forget to cite it in your bibliography.

i'm not using the video frame as the input..

i just need the ways to detect the empty parking lots in a static image and produce the output that can tell the user about the vacancy...

thank you for the link that you gave me..

but what should i do in order to read the journal/article on the site???
