We study the video steganography method in which the image is hidden in a video file. The method is based on the discrete wavelet transform. The video frames are transformed and then the proper positions of the coefficients are selected to hide the secret image pixels. The heuristic considers the coefficients that have the similar values to that of secret images. The similar values mean the same or the values that are closed to the cover media pixels. We compare this approach to the random coefficient selection approach as well as the methods using the discrete wavelet transform. Different payloads are also considered to study the effect of secrete image size to the cover video. The results shows that the lifting multiple wavelet transform with similar coefficients yields the best results for all the test case.
