I am looking for a solution for my problem. I have an image (see attachment), on which I want to detect all the cars. I tried to follow this
http://pythonvision.org/basic-tutorial/ but it seams that it is not suitable for my case, see some results in the attachment. I could not find any suitable example, and I do not have enough knowledge of the topic to be able to find solution myself. I can guess that I need some technique for shape detection but I cannot perform it directly.
Please help me with the procedure. It would be nice to have some step-by-step instruction on how to solve the problem.
Thank you.
