Using the Watermark Durability setting
The default Watermark Durability setting is designed to strike a balance between
watermark durability and visibility in most images. However, you can adjust the
Watermark Durability setting yourself to suit the needs of your images. Low values are less
visible in an image, but less durable, and may be damaged by applying filters or by
performing some image-editing operations, printing, and scanning operations. High
values are more durable but may display some visible noise in the image.
Your setting should depend on the intended use of the image and on the goals you’ve set
for your watermarks. For example, it may be quite acceptable to use a higher Watermark
Durability setting with JPEG images posted on a Web site. The higher durability helps to
ensure the persistence of the watermark, and the increased visibility often is not
noticeable with medium-resolution JPEG images. Digimarc recommends experimenting
with various settings as part of your testing process to determine which setting works best
for the majority of your images.
Using the signal strength meter
The signal strength meter helps you determine whether a watermark is durable enough to
survive the intended use of the image. The signal strength meter is available only for
images containing watermarks that you yourself have embedded.
Digimarc recommends that you check the signal strength meter before publishing your
images. For example, if you often compress watermarked images for inclusion in a Web
site, check the meter before posting the images. You can also use the signal strength
meter to gauge the effectiveness of different Watermark Durability settings that you are
experimenting with.
