SYNTAX

OutputImage = ipct_cvip(InputImage, EigenVector)

Input parameters include:

Output Parameter includes:

DESCRIPTION

This function converts the principle component tranform image back to an RGB image. The function uses the Eigen vectors, generated while performing the PCT on an image, to convert the PCT components to iPCT components for all the bands in the image. The Eigen vector has to be given as an input to the function by the user.

EXAMPLE

% Read image

 X = imread('Car.bmp');

% Call function

 [S1, E ,e] = pct_cvip(X);

 S2 = ipct_cvip(S1,E);

% Display input image

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

% Display output images

 figure;imshow(remap_cvip(S1),[]);title('Output image after pct');

 figure;imshow(remap_cvip(S2),[]);title('Output image afer inverse pct');
