template<class T >

vil_image_view< T > vil_decimate	(	const vil_image_view< T > &	im,
		unsigned	i_factor,
		unsigned	j_factor = 0
	)		[inline]

Create a view which is a decimated version of src.

Doesn't modify underlying data. O(1).

The factor describes the number of input rows (or columns) that are equivalent to one output. If you don't specify the j_factor, it will be set equal to i_factor.
