WebbHistogram filters decompose the state space into finitely many regions, and represent the posterior by a histogram. A histogram assigns each region a single cumulative probability; they are best thought of as piece wise constant approximations to a continuous density.

"WebbThe method allows us to compute the location, height, width and integral of all local histogram modes at interactive rates. Among other things, it enables the first constant-time isotropic median filter, robust isotropic image morphology operators, an efficient "dominant mode" filter and a non-iterative alternative to the mean shift.

WebbUse a zero-valued baseline. An important aspect of histograms is that they must be plotted with a zero-valued baseline. Since the frequency of data in each bin is implied by the height of each bar, changing the baseline or introducing a gap in the scale will skew the perception of the distribution of data.
