Data Hiding Scheme Designed for Binary Images using Combination Approaches
This paper proposes a binary image data embedding scheme utilizing a dithering algorithm and dithering mask to determine positions for data hiding. Additionally, a cover image is generated from the original image by an interpolation function to improve data hiding performance and maintain image quality. Experimental tests compare the proposed method to traditional PSNR and modified PSNR. The experimental results demonstrate stability in image quality and capacity.
