Class Integral_Image_GetRoiStatistics

Ch02_Histograms_Statistics.Integral_Image_GetRoiStatistics

All Implemented Interfaces:

PlugInFilter, JavaDocHelp

public class Integral_Image_GetRoiStatistics
extends Object
implements PlugInFilter, JavaDocHelp

This ImageJ plugin first calculates the integral image for the current image (8 bit grayscale only) and uses it to find the mean and variance inside the specified rectangle (ROI). Requires a rectangular ROI to be selected. Note that these values are directly obtained from the integral images and do not require any iterations over image pixels or other arrays. Thus such calculations are extremely quick. See Sec. 2.8 of [1] for additional details.
