In this paper, we focused on the information hiding for H.264/AVC and proposed a new hiding method which embeds information only by changing the value of the Intra 4x4 Prediction Mode. This method has merits in real time information embedding and compatible with H.264/AVC decoding. These are caused by the simple algorithm. From experimental results based on subjective and objective evaluations, it...
A fast intra mode decision algorithm for H.264/AVC is proposed in this paper. The objective is to reduce the encoder complexity without significant rate-distortion performance degradation. Three methods are adopted: (1) the block size is selected between 4times4 block and 16times16 block based on the smoothness and correlation information. (2) A characteristic is also exploited, which is using to...
