Homogeneity in ROI statistics

Home Forums Plugins Homogeneity in ROI statistics

  • Pedro Buzón

    Hello,

    I am very interested in the calculation of the homogeneity parameter provided within the ROI statistics plugin. Could you describe how is this parameter calculated? I could not find documentation about it.

    Thank you,

    Pedro

    Hi Pedro,

    Homogeneity descriptor is based on Haralick texture features, more exactly it’s the inverse difference moment.

    You can have more information about Haralick texture features here:
