In this paper, a new watermarking algorithm on video frame is proposed. The proposed algorithm divides a cover image frame into three color bands of red, green and blue. Then the following tasks are done on all three channels separately. First, Each color band is divided into patches of small sizes then the entropy of each patch is calculated. At this step a threshold is found based on the average entropy of all patches and following is applied to all patches which have entropy lower than the threshold. A wavelet representation of each patch is given by applying a discrete wavelet transform. Then Singular value decomposition, orthogonal-triangular decomposition, and a chirp z-transform are used to embed a watermark on the cover video frame. Several signal processing attacks are applied on watermarked video in order to robustness of the algorithm.
