| indeed, achieving high hiding capacity (HC), imperceptibility, and security are crucial challenges in image steganography. In the context of the paper you mentioned, a hybrid approach combining the Knight tour algorithm and Pixel Value Difference (PVD) has been proposed to address these challenges. The Knight tour algorithm, known for its ability to traverse a chessboard without repeating squares, is utilized in conjunction with PVD. This combination likely allows for efficient and secure embedding of data within the image. Experimental results reported in the paper indicate that this hybrid technique achieves a high Peak Signal-to-Noise Ratio (PSNR), which indicates good image quality and minimal distortion. Additionally, it demonstrates strong security, implying that the embedded data is well-hidden and resistant to detection. By leveraging the strengths of both the Knight tour algorithm and PVD, this hybrid approach appears to provide a promising solution that balances hiding capacity, imperceptibility, and security in image steganography. It is important to note that further analysis and evaluation of this technique would be necessary to assess its performance across different image datasets and potential vulnerabilities. | ||||
