This paper introduces the concept of a pixogram which makes possible a fresh approach to high payload video steganography. The pixogram allows for a new perspective by investigating the temporal changes that take place at the individual pixel level across frames of a video segment. Simply put, a pixogram has the property of converting highly uncorrelated spatial areas of individual frames of a video scene into highly correlated temporal segments by making use of the temporal correlation between the frames of the same scene in a given video segment, thus maximizing the redundant area suitable for hiding in the transform domain. Experimental results demonstrate the effectiveness of this new approach for increased payload capacity while maintaining visual fidelity of the stego-video as compared to competing video steganography schemes.
