Description Usage Arguments Details Author(s)

Wrapper for find_sticker it finds three similar objects. It assumes that there are three objects that can be found with find_sticker which are named "topleft", "topright", and "bottomleft".

find_three_stickers(img, topleft.min = c(0.1, 0.25, 0.25),
  topleft.max = c(0.25, 0.3, 0.4), topright.min = c(0.1, 0, 0.1),
  topright.max = c(0.2, 0.15, 0.3), bottomleft.min = c(0.2, 0.1, 0.1),
  bottomleft.max = c(0.4, 0.2, 0.2), return.img = FALSE)

`img`	Image object. From EBImage.
`topleft.min, topleft.max`	The minimum and maximum RGB values defining a range on which a feature at position "topleft" is expected to exist.
`topright.min, topright.max`	Similar to above, but for an element at position topright.
`bottomleft.min, bottomleft.max`	Similar to above, but for an element at position bottomleft.
`return.img`	NOT IMPLEMENTED. Logical, indicating whether to return the masked object(s).

This function was designed with a specific setup in mind. Namely the need to identify a rectangular area that is defined by three colored points on each of three of its vertices. See the file example1.jpeg included with this package for an example.
