    Abstract: The present disclosures relates generally to digital watermarking and data hiding. One claim recites a method comprising: obtaining data representing captured imagery, the captured imagery depicting packaging including digital watermarking, the digital watermarking including an orientation signal that is detectable in a transform domain; generating a n-dimensional feature set of the data representing captured imagery, the n-dimensional feature set representing the captured imagery in a spatial domain, where n is an integer great than 13; using a trained classifier to predict the presence of the orientation signal in a transform domain from the feature set in the spatial domain. Of course, other claims and combinations are provided too.

    Abstract: The present disclosure provides methods and systems for processing data. One claim recites a camera-equipped portable computer system, comprising: a camera; one or more processors programed for: i) controlling the camera to capture image data, the captured image data corresponding to the camera's field of view; ii) defining a sub-region comprising image data within the field of view, the sub-region comprising less image data than does the full field of view; and iii) searching image data within the field of view for hidden keys, but limiting a response to detected keys to those only found within the sub-region. Of course other claims and combinations are provided too.

    Abstract: An image can be encoded to define one or more spatial regions that are detectable by a suitably-equipped mobile device (e.g., a smartphone), but are imperceptible to humans. When such a mobile device senses one of these regions, it takes an action in response (e.g., rendering an associated tone, playing linked video, etc.). The mobile device may send an excerpt of captured imagery to a cloud processor, which responds with an estimate of the viewing angle by which the image was captured. The mobile device can perform further operations (e.g., re-sampling, watermark decoding) based on this viewing angle estimate. A great variety of other features and arrangements are also detailed.

    Abstract: A method of embedding information in an input image, wherein the information includes a plurality of characters, includes: utilizing a processing circuit to receive the information and convert each character included in the information into a corresponding symbol according to a conversion look-up table; setting a position of the corresponding symbol of each character in a data block according to a sequence look-up table to generate the data block; and adding at least the data block to the input image.
