The filter extracts the edge pixels of an image as points and stores them in an UnstructuredGrid. Every pixel which grey value is between the mean +- standard deviation * (2 or 3), will be extracted as point. The DetectionMethod can be set to choose if the doubled or tripled standard deviation is used. More...

Detailed Description

The filter extracts the edge pixels of an image as points and stores them in an UnstructuredGrid. Every pixel which grey value is between the mean +- standard deviation * (2 or 3), will be extracted as point. The DetectionMethod can be set to choose if the doubled or tripled standard deviation is used.

Member Enumeration Documentation

enum mitk::ImageToPointCloudFilter::DetectionMethod

The method which calculates and extracts the edge pixels/points. For the edge detection the laplacian filter is used and for extraction the standard deviation multiplied with 2, 3 or 4 (depending on selected method) is used.
