This paper introduced a watermarking method using the CRT and Canny Algorithm that able to improve the imperceptibility of watermarked image and preserving the robustness of watermark image as well. The classical CRT algorithm is spread the watermark bits evenly on the image area. It causes significant degradation when the embedding location lies on the least significant region or in the homogeny...
Slantlet Transform (SLT) is an improved performance from Discrete Wavelet Transform (DWT). Based on characteristic on SLT; piecewise linear, two zero moments, and power quality for data compression. Those characteristic proves efficiency of SLT. One of the characteristic of SLT named power quality is better than Discrete Cosine Transform (DCT). DCT has a good signal compression. Their capability for...
