... algorithms (triplets and quads) have almost the same performance with all images (except Le na at PSNR greater than 30 dB). From the results above and from the comparison with Celik and Tian, the spatial quad-based ... proposed algorithm can conceal more information than Tian’s and Thodi’s methods, while the performances of Alattar scheme are similar. In general, the proposed scheme i...
