A Spatial Domain Technique for Digital Image Authentication and Tamper Recovery
Monalisa Swain,Debabala Swain +1 more
TL;DR: In this article, a blind watermarking technique for image authentication and recovery of tampered area is proposed, which is done in block-wise manner by dividing the original image into non-overlapping blocks of 4*4 sizes.

Hybrid Encoding Scheme for AMBTC Compressed Images Using Ternary Representation Technique
TL;DR: An efficient method to improve the compression performance of AMBTC by classifying image blocks into flat, smooth, and complex blocks according to their complexity, which achieves higher image quality at a better compression ratio.

Image quality assessment: from error visibility to structural similarity
TL;DR: In this article, a structural similarity index is proposed for image quality assessment based on the degradation of structural information, which can be applied to both subjective ratings and objective methods on a database of images compressed with JPEG and JPEG2000.

UCID: an uncompressed color image database
Gerald Schaefer,Michal Stich +1 more
TL;DR: A new dataset, UCID (pronounced "use it") - an Uncompressed Colour Image Dataset which tries to bridge the gap between standardised image databases and objective evaluation of image retrieval algorithms that operate in the compressed domain.

Segmentation-Based Image Copy-Move Forgery Detection Scheme
TL;DR: The main difference to the traditional methods is that the proposed scheme first segments the test image into semantically independent patches prior to keypoint extraction, and the copy-move regions can be detected by matching between these patches.
Journal ArticleDOI
A hierarchical digital watermarking method for image tamper detection and recovery
TL;DR: This method is efficient as it only uses simple operations such as parity check and comparison between average intensities and effective because the detection is based on a hierarchical structure so that the accuracy of tamper localization can be ensured.

Dual watermark for image tamper detection and recovery
Tien-You Lee,Shinfeng D. Lin +1 more
TL;DR: By using the proposed algorithm, a 90% tampered image can be recovered to a dim yet still recognizable condition (PSNR ~20dB).
