Spatial Filtering Detection

This is the code for the ICIP 2015 paper titled SPATIAL DOMAIN FILTERING DETECTION.

The algorithm performs denoising using HMRF model. The compression noise is then used to determine if the given image is filtered or not.
Image = imread('ucid00001.tif');
imwrite(Image,'jff.jpg','Quality',70);
JpgImage = imread('jff.jpg');
[denoisedimage,noise]=noise_finalone(JpgImage,70,1,10);
Finalfeat = extract_TPM(noise,'truncate',15)
Finalfeat can be used to train and test. The images can be obtained from UCID database.
