Graffiti Detection

edit

Hi,

I wanted to consult with the forum about the problem of detecting Graffiti in images.

The directions I was thinking of are looking for very strong gradients and a lot of color changes.

Basically, I think that graffiti tends to be non-smooth, so perhaps looking for strong gradients can help.

I would be very glad to get some other ideas and directions on this problem :)

Thanks in advance!
