// Histogram Sample
// This sample shows how to use the Sample Grabber filter for video IMAGE processing.
// Conceptual background:
// A histogram is just a frequency count of every pixel value in the IMAGE.
// There are various well-known mathematical operations that you can perform on an IMAGE
// using histograms, to enhance the IMAGE, etc.
// Histogram stretch (aka automatic gain control):
// Stretches the IMAGE histogram to fill the entire range of values. This is a "point operation,"
// meaning each pixel is scaled to a new value, without examining the neighboring pixels. The
// histogram stretch does not actually require you to calculate the full histogram. The scaling factor
// is calculated from the minimum and maximum values in the IMAGE.
