This Matlab code package implements the image interpolation algorithm based on the directional cubic convolution interpolation which has been described in the following paper:
D. Zhou, X. Shen, and W. Dong,
Image zooming using directional cubic convolution interpolation,
IET Image Processing, Vol. 6, No. 6, pp. 627-634, 2012.

This package includes 3 functions:
DCC.m - core algorithm
Calc_MSE_SNR.m - compute MSE, SNR and PSNR
testDCC.m - test function for the core algorithm

It also includes 2 folds. The fold original_images includes the all original images used in the paper, and the fold resulted_images is used to save the resulted images.
