    • process

      public int[] process​(ij.process.ImageProcessor binaryImage)
      Computes the histogram of binary configurations for the region within the input binary image. Takes into account the border of the image: histogram considers all the 2-by-2 configurations that contain at least one pixel of the image.
      Parameters:
      binaryImage - the input image containing the region the analyze
      Returns:
      an array of integers containing the 16-elements histogram of binary configurations
      See Also:
      processInnerFrame(ImageProcessor)

    • processInnerFrame

      public int[] processInnerFrame​(ij.process.ImageProcessor binaryImage)
      Applies a look-up-table for each of the 2x2 pixel configurations with all pixels within the input binary image, and returns the sum of contributions for each label. This method is used for computing densities of Euler number, perimeter and area from binary images.
      Parameters:
      binaryImage - the input 2D binary image
      Returns:
      an array of 16 integers containing the number of each binary configurations
      See Also:
      process(ImageProcessor)

    • process

      public int[][] process​(ij.process.ImageProcessor labelImage, int[] labels)
      Computes the histogram of binary configurations for each region of the input label image. Takes into account the border of the image: histograms consider all the 2-by-2 configurations that contain at least one pixel of the image.
      Parameters:
      labelImage - the input image containing region labels
      labels - the list of region labels
      Returns:
      an array of integer containing for each region, the 16-elements histogram of binary configurations
