public class CompsConvertUtils
extends java.lang.Object

This class contains several functions which are useful to convert the identification of the components from an one-dimesion array of integers or booleans to a two-dimension array of integers with ranges of components, and vice-versa.

Method Detail

componentsToRangeOfComponents

@Deprecated
public static int[][] componentsToRangeOfComponents(int[] comps,
                                                               int maxComps)

Deprecated.

This method converts the number of components from an array structure to an array of ranges.

Parameters:

comps - an array with the component number.

maxComps - is the maximum number of components

Returns:

an array of ranges.

componentsToRangeOfComponents

public static int[][] componentsToRangeOfComponents(int[] comps)

This method converts the number of components from an one-dimension array structure to a two-dimension array with ranges of components. This method supposes that the input one-dimensional array has not repeated values. Otherwise, output data could not be obtained or it could be wrong.

Parameters:

comps - an array with the component number.

Returns:

an array of ranges.

rangeOfComponentsToComponents

public static int[] rangeOfComponentsToComponents(int[][] rangeOfComps)

This method converts form a bi-dimensional array with the ranges of components (first and last component) to an one-dimensional array with the number of the components.

Parameters:

rangeOfComps - a bi-dimensional array with the ranges of the components. The first dimension is the index of the range and the second dimension indicates: 0 the first component of the range, and 1 the last component of the range.

Returns:

a one-dimension array with the components.

rangeOfComponentsToComponentsExpanded

public static boolean[] rangeOfComponentsToComponentsExpanded(int[][] rangeOfComps,
                                                              int maxComps)

This method converts form a bi-dimensional array with the ranges of components (first and last component) to an one-dimensional array with the number of the components.

Parameters:

rangeOfComps - a bi-dimensional array with the ranges of the components. The first dimension is the index of the range and the second dimension indicates: 0 the first component of the range, and 1 the last component of the range.

maxComps - is the maximum number of components.

Returns:

a one-dimension array of booleans. If the index is true , it means the component is chosen. Otherwise, it is not chosen.

componentsExpandedToRangeOfComponents

public static int[][] componentsExpandedToRangeOfComponents(boolean[] comps)

Changes the representation from the components as an one-dimensional array to a bi-dimensional array of ranges. The input parameter comps is an one-dimensional with length the maximum image components where the selected components are true.

Parameters:

comps - an one-dimensional array with the indexes of the selected components set to true value.

Returns:

a bi-dimensioal array of component ranges.

joinOverlapedRanges

public static int[][] joinOverlapedRanges(int[][] compsRanges)

This method joins overlaped ranges of components.

Parameters:

compsRanges -

Returns:

a bi-dimension array with the joined range of components.
