## NAME

         sct_split_segment - performs Spherical Coordinate  Transform
         segmentation

## SYNOPSIS

          #include "CVIPcolor.h"
          #include "CVIPdef.h"
          #include "SCTsplit.h"

          Image *sct_split_segment (Image  *imgP,  int  A_split,  int
         B_split)

          <imgP> - address of pointer to Image structure
          <A_split> - number of colors to divide along angle A
          <B_split> - number of colors to divide along angle B

## PATH

         $CVIPHOME/SEGMENTATION/sct_split.c

## DESCRIPTION

         The  Spherical Coordinate Transform  segmentation  algorithm
         (SCT/Center  split) was developed for use in the identifica-
         tion of variegated coloring in skin tumor images. The  algo-
         rithm  maps  RGB data into a space defined by two angles and
         an intensity measure. Then  the  subspace,  defined  by  the
         minimums  and maximums on the two angles, is equally divided
         along each axis, using the two input parameters, A_split and
         B_split.

## TYPES AND CONSTANTS

## RETURN VALUES

         The segmented image.

## EXAMPLE

          #include "CVIPtoolkit.h"
          #include "CVIPconvert.h"
          #include "CVIPcolor.h"
          #include "CVIPdef.h"
          #include "sct_split.h"

          void main()
          {
          Image *cvipImage;
          IMAGE_FORMAT format;
          char *inputfile, *outputfile;
          int Asplit, Bsplit;

          setDisplay_Image("picture", "Default");

          print_CVIP("\n\t\tEnter the Input File Name:  ");
          inputfile =(char *) getString_CVIP();
          cvipImage = read_Image(inputfile, 1);
          view_Image(cvipImage, inputfile);
          Asplit = Bsplit = 3;
          cvipImage = sct_split_segment(cvipImage, Asplit, Bsplit);
          print_CVIP("\n\t\tEnter the Output File Name:  ");
          outputfile = getString_CVIP();
          view_Image(cvipImage, outputfile);
          format = getFileFormat_Image(cvipImage);
          write_Image(cvipImage,outputfile,CVIP_NO,CVIP_NO,format,1);
          free(inputfile);
          free(outputfile);
          }
