Detailed Description

pixel value histogram of 2D image

The vepl1_histogram class creates a pixel value histogram of a 2D image and writes it into a vcl_vector<unsigned int>.

The number of bins for ubyte images is 256, for ushort images 65536, and for float or double image it is 1000.

Note that, as opposed to vipl_histogram, the output bins are initialised to 0, as one expects.
