In this paper, we propose an adaptive embedding methods for reversible data hiding. Embedding threshold is a very important factor in reversible data hiding, where the proper embedding threshold can produce the best performance. For previous reversible data hiding methods, only 1 threshold is used in the embedding procedure, we propose a two thresholds selection method. The image is divided into 2 parts, each part uses 1 proper threshold to embed dta. The experiment shows that the proposed method outperforms the previous methods.
