Example

nucleus    results table

Description

Computes the central moments up to the third order and 7 features build from the central moments that are invariant against translation and rotation. Computes either the moments for the whole image or within the rectangular selection.

You can find the definition of the features in:
Seminarband der Projektgruppe 294 - BAMBUS - Baukasten für die Analyse und Modellierung von Bildobjekten aufgrund unscharfen Wissens, University Dortmund, Internal Reports, 1996,  page 72  (or in this document: mustererkennung.pdf). They have originally been taken from:
Heinrich Niemann, Klassifikation von Mustern, Springer-Verlag Berlin Heidelberg, 1983

Options

The operation has no options.

Parameter

The only parameter is the input image. If there is a ROI on the image the bounding box of the ROI is taken into account.

Results

A results table with the central moments up to the third order and the 7 rotation and translation invariant features calculated from them.
