summary(object, plot = FALSE, axes = TRUE, col = NULL, ...)

Arguments

object

(required) an image of class rimg, or list thereof.

axes

should axes be drawn when plot = TRUE? (defaults to TRUE).

col

optional vector of colours when plotting colour-classified images with plot = TRUE. Defaults to the mean RGB values of the k-means centres (i.e. the 'original' colours).

...

additional graphical options when plot = TRUE. Also see par().
