Result Description
Statistics

View the following histogram statistics: 

  • The minimum histogram bin index that contains a non-zero pixel count
  • The maximum histogram bin index that contains a non-zero pixel count
  • The histogram bin index of the bin containing the median (middle) pixel value in the histogram. This is the histogram bin index where half of the distribution of pixel values is above and half below it.
  • The histogram index of the bin containing the mode (most common) pixel value
  • The arithmetic mean (average) pixel value in the image
  • The standard deviation of the pixel values in the image
  • The variance of the pixel values in the image
  • The number of pixels in the histogram
Data

Displays the following information about each bin in the histogram: 

  • The count of pixels in that bin
  • The cumulative percentage of image pixels at that bin

By default the number of bins in the histogram corresponds to the maximum possible pixel value in the image; 256 for 8-bit greyscale images up to 65,536 for 16-bit greyscale images.
