Class ImplMedianHistogramInner_MT


@Generated("boofcv.alg.filter.blur.impl.ImplMedianHistogramInner") public class ImplMedianHistogramInner_MT extends Object

A faster version of the histogram median filter that only processes the inner portion of the image. Instead of rebuilding the histogram from scratch for each pixel the histogram is updated using results from the previous pixel. When computing the histogram the previous median is used as a hint to the new median. The original implementation is similar to the algorithm proposed in [1]. If you need to cite something cite this library and mention that paper.
