Claim:
1. A method comprising: 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, in which the input color mode corresponds to or is compatible with a color space associated with the reader; estimating a signal strength of the watermark signal within the transformed watermark image data; and visually displaying the estimated signal strength spatially relative to the image data, with a first color representing first signal strength and a second color representing second signal strength, in which the second signal strength comprises a higher signal strength relative to the first signal strength, and with a third color representing a third signal strength comprising a signal strength between the first signal strength and the second signal strength.
