Abstract: A watermark image may be generated that includes a first set of encoded pixels each of which is assigned a first transparency value and a second set of encoded pixels each of which is assigned a second transparency value, the second transparency level being different from the first transparency level. The encoded pixels may be distributed among a set of blank pixels such that each encoded pixel neighbors one or more blank pixels in the watermark image, and in particular at least two blank pixels in the watermark image. Herein, each blank pixel may be assigned the second transparency value. The watermark image may be overlaid and blended over a background source image to create an encoded source image. A decoder system may recover encoded information from the encoded source image.

Abstract: Embodiments of a shape measurement system and related methods are disclosed. In some embodiments, the system places a two-dimensional initial pattern, which can be implemented as a standalone molding or can be attached to a light source or printed on an outfit, onto a surface of a three-dimensional object. The system captures a transformed version of the initial pattern in two dimensions that is distorted due to the varying depth of the surface. The system then analyzes the transformed pattern and derives three-dimensional information regarding the target object. The analysis, which can incorporate a calibration process, can rely on the projection nature of the light source, the isomorphism/non-isomorphism of the initial pattern, and other factors.

Abstract: A random content messaging system and method are provided. The system and method allows users to submit content to a service and the system makes that content available for discovery, viewing and interaction by other users as unorganized random selection of items. The submitted content, in the form of threaded conversations, is only discoverable by users of the system via that random request & selection mechanism.
