The present invention relates to high quality composite materials from fibers such as glass, polyaramid or graphite fibers, where the composite incorporates a polymer matrix embedding individual fibers. The composites are lightweight materials displaying enhanced strength and durability. In one aspect, the polymer matrix is a thermoplastic or other polymer type that cannot easily penetrate gaps between individual fibers by typical methods for thermosets. The invention also relates to methods for forming composite materials, where the fiber is exposed to an emulsion including polymer particles having sufficiently small dimensions to allow impregnation into the fiber gaps. Composite sheets and articles are also described, as well as the formation of new composites for porous articles, e.g., ceramics or wood, where a polymer matrix is embedded within the pores.

The invention provides a video steganography algorithm based on a motion vector difference MVD based on an H.264/AVC video coding and decoding framework. Through proving connection between the motion vector difference and motion vector space-time correlation, a statistics characteristic of the motion vector difference is used to design an embedding rule. Through combining a matrix coding algorithm, a series of matrix embedding secret keys with different sizes are designed and secret information is adaptively embedded into a video compression process so that the motion vector difference can well maintain an original histogram characteristic before and after steganography. The algorithm possesses good visual invisibility and can well resist steganography analysis based on motion vector space-time correlation.
