Encoding Self-Embedded Sentences
Language and Speech, 1976Are encoding and decoding mirror image processes? Previous studies show that semantically supported self-embedded sentences are easier to decode than semantically neutral sentences. A procedure for testing encoding is developed. The hypothesis that semantically supported self-embedded sentences are not easier to encode than semantically neutral ...

Self Embedding Watermarking Scheme Using Halftone Image
IEICE Transactions on Information and Systems, 2008 Self embedding watermarking is a technique used for tamper detection, localization and recovery. This letter proposes a novel self embedding scheme, in which the halftone version of the host image is exploited as a watermark, instead of a JPEG-compressed version used in most existing methods.

Canadian Mathematical Bulletin, 1989
AbstractElementary proofs are given of the following two statements: (1) Every infinite tree of height at most ω properly embeds into itself. (2) There is a tree of height ω + 1 that does not properly embed into itself.

Self-embedding watermark with flexible restoration quality
Multimedia Tools and Applications, 2010A novel self-embedding watermarking scheme is proposed, in which the reference data derived from the most significant bits (MSB) of host image and the localization data derived from MSB and reference data are embedded into the least significant bits (LSB) of the cover.

Finite Automata and Non-self-Embedding Grammars
2003We consider non-self-embedding (NSE) context-free grammars as a representation of regular sets. We point out its advantages with respect to more classical representations by finite automata, in particular when considering the efficient realization of the rational operations.

Efficient Image Recovery Based on Self-Embedding
2008 Eighth International Conference on Intelligent Systems Design and Applications, 2008Due to the instability of and possible attacks on the networks, image files transmitted through the networks may encounter losses of data. Such losses may be recovered by retransmitting or by using image processing techniques. The latter has an obvious advantage that the network traffic could be reduced.

Image self-recovery with watermark self-embedding
Signal Processing: Image Communication, 2018Abstract In this paper, an effective image authentication method for image tamper detection and self-recovery is proposed. We embed the fragile watermark of one block which consists of authentication data and recovery data into the other block according to the embedding sequence generated by chaotic map.

Colour image authentication based on a self-embedding technique
2002 14th International Conference on Digital Signal Processing Proceedings. DSP 2002 (Cat. No.02TH8628), 2003In the paper an approach for digital image authentication is described. The authentication process is achieved by means of a watermarking scheme that embeds an approximation of the image into itself. Specifically, the luminance of the image is inserted into the three colour channels, using a mapping function.

Image self-embedding with high-quality restoration capability
Digital Signal Processing, 2011In this paper, we present a new fragile watermarking method aimed at providing improved restoration capability. A mechanism of block classification is used to compress the original image according to the DCT coefficients, in which blocks corresponding to different types are encoded to variable lengths. The compressed bits are expanded as reference bits,
