In distributed single-view video coding (DSVC) or distributed multiview video coding (DMVC), the compression performance is greatly affected by the quality of side information (SI). Most existing DSVC or DMVC schemes generate SI by employing motion estimation (ME) at the decoder. Since the original frame is unavailable, the ME accuracy is low. In this paper we propose a novel distributed coding scheme...
The key for real-time collection of cutting tool information and its process tracking is to realize the encoding means and automatic identification of tool information. Therefore, the authors propose to encode tool information in data matrix symbol and directly mark the symbol on tool surface. The tool information encoding scheme, the symbol image processing method and its error correction decoding...
Traditional watermarking techniques based on fractal coding are generally using 0, 1 sequence as watermark, thus impossible for gray image embedding. A novel fast watermarking technique is proposed in this paper to overcome the above mentioned shortage by employing the orthogonal fractal coding technique. With the proof that fractal decoding parameters during iterations is mean-invariant, watermarks...
