| float vifa_histogram::CompareToHistogram | ( | vifa_histogram * | h | ) | [inherited] |
Compare 'this' histogram to another (passed in).
Taken from the old TargetJr class HistEntropy.

| float vifa_histogram::ComputeArea | ( | ) | const [inherited] |
Compute the total area under the histogram.

| vifa_histogram * vifa_histogram::Cumulative | ( | ) | [inherited] |
Assuming that "this" is a histogram of population density, construct a new histogram which is the cumulative distribution.
Each bin, xi, in his is assumed to represent a density, i.e., {x | (xi - .5*delta) < x <= (xi + .5*delta)} Each bin, xi, in the result represents a cumulative distribution, i.e., {x | x <= (xi + .5*delta)}

| vifa_histogram * vifa_histogram::NonMaximumSupress | ( | int | radius = 1, |
| bool | cyclic = false |
||
| ) | [inherited] |
Suppress values in the histogram which are not locally.
The neighborhood for computing the local maximum a maximum. is [radius X radius], e.g. for radius =1 the neighborhood is [-X-], for radius = 2, the neighborhood is [--X--], etc. If the cyclic flag is true then the index space is assumed to be equivalent to a circle. That is, elements "0" and "n_buckets" are in correspondence.

Prints histogram counts onto vcl_cout.

| void vifa_histogram::RemoveFlatPeaks | ( | int | nbins, |
| float * | cnts, | ||
| bool | cyclic | ||
| ) | [inherited] |
Prune any sequences of more than one maximum value.
That is, it is possible to have a "flat" top peak with an arbitrarily long sequence of equal, but maximum values. The cyclic flag indicates that the sequence wraps around, i.e. cnts[0] equivalent to cnts[nbins]

| vifa_histogram * vifa_histogram::Scale | ( | float | scale_factor | ) | [inherited] |
Transform the value axis of a histogram by a translation, transl, and a scale factor, scale.
The new histogram has the same resolution as his.
