scripts default iconResize any arrays and images (Scripts) Publisher's description

Y = RESIZE(X,NEWSIZE) resizes input array X using a DCT (discrete cosine transform) method.

Y = RESIZE(X,NEWSIZE) resizes input array X using a DCT (discrete cosine transform) method. X can be any array of any size. Output Y is of size NEWSIZE.

Input and output formats: Y has the same class as X.

As an example, if you want to multiply the size of an RGB image by a factor N, use the following syntax:
newsize = size(I).*[N N 1];
J = resize(I,newsize);

% Upsample and stretch an RGB image
I = imread('onion.png');
sizeJ = size(I).*[2 2 1];
J = resize(I,sizeJ);
sizeK = size(I).*[1/2 2 1];
K = resize(I,sizeK);

Enter "help resize" to obtain other examples.

The functions DCTN and IDCTN are required. Visit:
