Method Detail

applyLut

public static final double applyLut(int[] histogram,
                                    double[] lut)

Applies look-up-table of values for each configuration, based on the array of count for each binary configuration.

Parameters:

histogram - the count of each type of 2-by-2 binary configurations, as an array

lut - the value to associate to each configuration

Returns:

the sum of the products of counts by the associated value

applyLut

public static final int applyLut(int[] histogram,
                                 int[] lut)

Applies look-up-table of values for each configuration, based on the array of count for each binary configuration.

Parameters:

histogram - the count of each type of 2-by-2 binary configurations, as an array

lut - the value to associate to each configuration

Returns:

the sum of the products of counts by the associated value

applyLut

public static final double[] applyLut(int[][] histograms,
                                      double[] lut)

Applies look-up-table of values for each configuration for each label, based on the 16-array of count for each binary configuration.

Parameters:

histograms - the count of each type of 2-by-2 binary configuration of each label, as a nLabels-by-16 array

lut - the value to associate to each configuration

Returns:

the sum of the products of counts by the associated value for each label

applyLut

public static final int[] applyLut(int[][] histograms,
                                   int[] lut)

Applies look-up-table of values for each configuration for each label, based on the 16-array of count for each binary configuration.

Parameters:

histograms - the count of each type of 2-by-2 binary configuration of each label, as a nLabels-by-16 array

lut - the value to associate to each configuration

Returns:

the sum of the products of counts by the associated value for each label

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
