An Adaptive Embedding Strength Watermarking Algorithm Based on Shearlets’ Capture Directional Features
The discrete wavelet transform (DWT) is unable to represent the directional features of an image. Similarly, a fixed embedding strength is not able to establish an ideal balance between imperceptibility and robustness of a watermarked image. In this work, we propose an adaptive embedding strength wa...
