// 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.
