EXTERNAL ATTACKS EFFECT ON DC COEFFICIENTS OF DCT MATRIX OF STILL SEMITONE IMAGES
Annotation
The subject of this article is an external attacks effect on DC coefficient of semitone image DCT matrix. The goal of this analysis is a convenience determination of using DC coefficients as a data hide area for steganography algorithms. Resizing, Gaussian noise, filtering and JPEG compression are used as an external attacks.
