METHODS FOR ESTIMATING WATERMARK SIGNAL STRENGTH, AN EMBEDDING PROCESS USING THE SAME, AND RELATED ARRANGEMENTS |
摘要 |
The present disclosure relates to advanced signal processing including digital watermarking and steganography. One method includes: obtaining image data representing imagery in a first color mode; steganographically embedding a watermark signal into the image data, thereby generating watermarked image data; obtaining reader data representing an input color mode of a reader configured to detect or decode the watermarked image data, wherein the input color mode is different from the first color mode; transforming the watermarked image data from the first color mode to the input color mode; estimating a signal strength of the watermark signal within the transformed watermark image data; and visually displaying the estimated signal strength. The estimated signal strength can be visually displayed as a multi-color heat map. Of course, other combinations are described as well. |
