Appl. 29, 990–993 (2009) About this Chapter Title Reversible Watermarking Based on Prediction-Error Expansion for 2D Vector Maps Book Title Emerging Technologies for Information Systems, Computing, and Management Book Part Part Zhao, R. RONI is identified by segmenting the lung tissue from the CT scan image.

The corresponding ones with proposed improvement version (OELM-MED) are 2.908 per pixel for Lena, 3.360 per pixel for Jet, and 11.416 per pixel for Mandrill, respectively. Instead of embedding the entire expanded difference into the current pixel, the expanded difference is split between the current pixel and its prediction context with global optimization, and Coltuc’s scheme achieved Meanwhile, the modification on the current pixel’s context may enlarge the distortion induced by the prediction of its successors.

Comparison with Other Non-PE Based SchemesFigure 16 shows the performance comparisons between proposed scheme and other non-PE based schemes [21, 22, 37] in terms of the pure hiding rate and PSNR As a kind of high-performance predictor, MED has been utilized in some reversible watermarking schemes [13–15] and also in JPEG-LS standard [25].

Li, “Incremental learning for ν-support vector regression,” Neural Networks, vol. 67, pp. 140–150, 2015. Moreover, some reversible watermarking algorithms, combining histogram shifting with prediction technique, are presented to satisfy both high embedding capacity and good visual quality [11, 12].The prediction-error expansion (PE) algorithm was developed In addition, through the experimental contrast and theoretical analysis between the proposed approach and the noted improvement embedding scheme proposed by Coltuc [15], it is observed that the proposed approach outperforms https://www.researchgate.net/publication/4138017_Prediction-error_based_reversible_watermarking Full-text · Article · Jun 2015 I.

Coltuc’s scheme is designed to decrease the embedding distortion, of which the basic idea is to share the expanded difference between the current pixel and its prediction context. Compared with neural network (NN) [27, 28] and support vector machine (SVM) [29–31], ELM greatly improves the generalization ability and learning speed of the network [23]. Prediction-error based reversible watermarking. This paper investigates the concept of prediction error expansion in developing a fragile reversible data hiding technique for digital images.

This reversibility enables the recovery of the original host content upon verification of the authenticity of the received content. http://bsdupdates.com/prediction-error/prediction-error-signals.php If more payloads need to be embedded, we can achieve embedding more payloads through multiple runs of watermarking embedding process.Figure 7: Pure hiding rate with respect to the embedding threshold on Thodi and J. The least significant bits (LSBs) of first pixels of the image form a sequence noted as , which is utilized for the lossless image restoration, and then in terms of (2),
