SYNTAX

outImage  = pct_median_cvip( inImage, numColors )

Input Parameters include :

inImage - 1-band input image of MxN size or 3-band input image of MxNx3 size. The input image can be of uint8 or uin16 or double class.
numColors - Number of colors. NumColors = 2(default)

Output Parameter include :

outImage - Segmented image having same size of input image.

DESCRIPTION

The function performs the principal components transform (PCT) of the input image, and then performs the Median cut segmentation. The segmented image in PCT domain will be mapped back to original 3-D color space by taking inverse-PCT.

EXAMPLE

 %original image

 I = imread('butterfly.tif');

 % default numColors = 2

 O1 = pct_median_cvip(I);

 N = 8;                         %number of colors

 O2 = pct_median_cvip(I,N);     %numColors = 8

 % Display input image

 figure;imshow(I);title('Input image');

% Display output image

 figure;imshow(remap_cvip(O1,[]));title('Output image with default parameters');

 figure;imshow(remap_cvip(O2,[]));title('Output image with user defined parameters');
