public class BlockStatistics extends Object
integral images. At this time, it is
implemented for single channel images at floating point accuracy only, RGB
is transferred into grey, integer accuracy into floating point accuracy
accordingly. That is, for processing multiple color channels, separate them
into individual ImageProcessors first and execute the
calculation on each of them individually.| Modifier and Type | Class and Description |
