Histogram shifting
Webb4 jan. 2024 · In light of this, some sorted prediction errors with less complexity are selected to be efficiently used for low-distortion data embedding with a traditional histogram shift scheme. Experimental results demonstrate that the proposed method can achieve better embedding performance than that of the CNN predictor with the same histogram … Webb24 mars 2024 · Histogram shifting is one of the most popular techniques for achieving reversible data hiding technology. However, invalid shifting in histogram shifting limits the performance of existing reversible data hiding schemes.

Webb近年来,可逆信息隐藏技术(Reversible Data Hiding,简称RDH)发展迅速,已经形成了一系列如直方图移位(Histogram Shifting,简称HS),预测误差扩展(Prediction-Error Expansion,简称PEE)等经典RDH框架,且目前的研究大体沿着PEE框架的两大步骤进行探索,一是提升预测性能以获得分布更加集中的直方图,二是优化HS方案,自适应设 … Webb31 mars 2024 · In the histogram shift method, the histogram is generated from the values in the frame or image. The idea of embedding is to move the histogram to provide space for the peaks, which can be embedded. In this algorithm, the histogram only moves toward zero, and the number of embeddings corresponds to the number of bits at the …
WebbThe existing histogram shifting reversible data hiding scheme has been presented based on finding the values of the peak point and the zero point and then moving the histogram to modify the relevant pixel values to embed information.
