Abstract
Methods, devices, and processor-readable media for digital image watermarking, including performing one or more decoding operations that each include generating a respective intermediate watermark embedding feature tensor that includes one or more representations of a watermark message embedded into a feature tensor generated by a preceding decoding operation; upscaling the respective intermediate watermark embedding feature tensor to generate a further feature tensor; and generate a watermarked image based on the further feature tensor.
Claims20
A computer-implemented method of digital image watermarking comprising:
- performing a set of decoding operations to generate a watermarked image corresponding to a first latent feature tensor, comprising:
- performing a first decoding operation in the set of decoding operations, comprising:
- generating a first watermark embedding feature tensor that includes one or more representations of a watermark message embedded into the first latent feature tensor, and
- upscaling the first watermark embedding feature tensor to generate a respective upscaled feature tensor;
- performing one or more successive intermediate decoding operations in the set of decoding operations subsequent to the first decoding operation, each respective intermediate decoding operation comprising:
- generating a respective intermediate watermark embedding feature tensor that includes one or more representations of the watermark message embedded into the upscaled feature tensor generated by a preceding decoding operation of the set of decoding operations, and
- upscaling the respective intermediate watermark embedding feature tensor to generate a further upscaled feature tensor;
- and
- performing a final decoding operation in the set of decoding operations subsequent to a final intermediate decoding operation of the one or more successive intermediate decoding operations, the final decoding operation comprising:
- generating a final watermark embedding feature tensor that includes one or more representations of the watermark message embedded into the upscaled feature tensor generated by the final intermediate decoding operation, and
- upscaling the respective final watermark embedding feature tensor to generate the watermarked image.
