A new robust watermarking algorithm based on intra-frame difference
TL;DR: Based on spatial domain intra-frame difference, a new robust video watermarking algorithm is proposed in this paper , where frame sequences of the to-be-marked digital video are grouped based on the time period.

Embedding Multi-Bit Message in the Joint Time-Frequency Domain
TL;DR: A new multi-bit watermarking method in the joint time-frequency domain is introduced, where the Wigner distribution for the edges of an image is computed and the time- frequencies that are robust to attacks are used for watermark embedding.

Multimedia Security through LSB Matching
TL;DR: An efficient image steganography technique which provides high embedding capacity as well as imperceptibility of stego image and gives better results than simple LSB and inverted LSB with higher PSNR and lower MSE is proposed.

Rifat Kurban,Hakkı Bozpolat +1 more
TL;DR: In this paper , Çoklu-adaptif ölçekleme faktörleri kullanan önerilen yöntemde, damgalanacak görüntünün tüm blokları uzaysal resim frekansı (URF) metriği ile değerlendirilmiş ve her bloğa doku miktarıyla orantılı olarak.
Survey paper on Copyright Protection for Images on Mobile Devices
TL;DR: The upcoming era of mobile technology has also raised by sharing of images and other graphical data, and protection to such files is also plays a vital role with watermarking.

Secure spread spectrum watermarking for multimedia
TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.

Techniques for data hiding
TL;DR: This work explores both traditional and novel techniques for addressing the data-hiding process and evaluates these techniques in light of three applications: copyright protection, tamper-proofing, and augmentation data embedding.

A digital watermark
TL;DR: The paper discusses the feasibility of coding an "undetectable" digital water mark on a standard 512/spl times/512 intensity image with an 8 bit gray scale, capable of carrying such information as authentication or authorisation codes, or a legend essential for image interpretation.

Image coding based on a fractal theory of iterated contractive image transformations
TL;DR: The author proposes an independent and novel approach to image coding, based on a fractal theory of iterated transformations, that relies on the assumption that image redundancy can be efficiently exploited through self-transformability on a block-wise basis and approximates an original image by a Fractal image.
