Crop image on special color pixels

Question

hi
i have some images contains some orange circles. i need to crop that circles from image... this circles location is not the same and is not stable.. their locations are variable... so i can't use ROI or use start point or end point or point of the center of that circle, because in every image it's in a different location and also there are a lot of images.

so how can i crop images on circles location? i think i must use colors for cropping but i don't know how,
thanks in advance

First of all be sure that you are importing/using (depending on language) the System.IO namespace for this to work. But what you can do is something like this

string pathToCreate = "~/UserFolders/" + TextBox1.Text;

if(Directory.Exists(Server.MapPath(pathToCreate))

{

   //In here, start looping and modify the path to create to add a number

   //until you get the value needed

}

 

//Now you know it is ok, create it

Directory.CreateDirectory(Server.MapPath(pathToCreate));
