Embedding of binary image in the Gray planes

TL;DR

This paper explores embedding binary images into Gray planes of grayscale images for watermarking, demonstrating increased robustness against JPEG compression compared to traditional bit plane methods.

Contribution

It introduces a Gray plane-based embedding method for binary images and analyzes its robustness against JPEG lossy compression.

Findings

Binary image embedding in Gray planes is more robust to JPEG compression.

Gray plane embedding outperforms bit plane embedding in robustness.

The method facilitates improved watermark detection in compressed images.

Abstract

For watermarking of the digital grayscale image its Gray planes have been used. With the help of the introduced representation over Gray planes the LSB embedding method and detection have been discussed. It found that data, a binary image, hidden in the Gray planes is more robust to JPEG lossy compression than in the bit planes.
