摘要： Spectral encoding methods are more robust when used with improved weak signal detection and synchronizations methods. Further robustness gains are achieved by using informed embedding, error correction and embedding protocols that enable signal to noise enhancements by folding and pre-filtering the received signal.

摘要： The present disclosure relates to signal processing such as digital watermarking and data hiding. A sparse or dense digital watermark signal can be conveyed with a narrow-band absorption material corresponding to a center wavelength of a Point of Sale (POS) barcode scanner. The POS barcode scanner typically captures 2D imagery. Since the narrow-band absorption material absorbs over a narrow-band it is relatively imperceptible to the Human Visual System (HVS) but can be seen by the POS scanner.

摘要： Signal detection and recognition employees coordinated illumination and capture of images under to facilitate extraction of a signal of interest. Pulsed illumination of different colors facilitates extraction of signals from color channels, as well as improved signal to noise ratio by combining signals of different color channels. The successive pulsing of different color illumination appears white to the user, yet facilitates signal detection, even for lower cost monochrome sensors, as in barcode scanning and other automatic identification equipment.

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.

摘要： Content signal recognition is based on a multi-axis filtering of the content signal. The signatures are calculated, formed into data structures and organized in a database for quick searching and matching operations used in content recognition. For content recognition, signals are sampled and transformed into signatures using the multi axis filter. The database is searched to recognize the signals as part of a content item in the database. Using the content identification, content metadata is retrieved and provided for a variety of applications. In one application, the metadata is provided in response to a content identification request.

摘要： A smart phone senses audio, imagery, and/or other stimulus from a user's environment, and acts autonomously to fulfill inferred or anticipated user desires. In one aspect, the detailed technology concerns phone-based cognition of a scene viewed by the phone's camera. In one detailed arrangement, image processing tasks applied to the scene are selected from among various alternatives by reference to resource costs, resource constraints, other stimulus information (e.g., audio), task substitutability, etc. The phone applies more or less resources to an image processing task depending on how successfully the task is proceeding, or based on the user's apparent interest in the task. In another detailed arrangement, data is referred to the cloud for analysis, or for gleaning. In still another detailed arrangement, cognition, and identification of appropriate device response(s), is aided by collateral information, such as context. A great number of other features and arrangements are also detailed.

摘要： Mobile phones and other portable devices are equipped with a variety of technologies by which existing functionality can be improved, and new functionality can be provided. Some aspects relate to visual search capabilities, and determining appropriate actions responsive to different image inputs. Others relate to processing of image data. Still others concern metadata generation, processing, and representation. Yet others concern user interface improvements. Other aspects relate to imaging architectures, in which a mobile phone's image sensor is one in a chain of stages that successively act on packetized instructions/data, to capture and later process imagery. Still other aspects relate to distribution of processing tasks between the mobile device and remote resources (“the cloud”). Elemental image processing (e.g., simple filtering and edge detection) can be performed on the mobile phone, while other operations can be referred out to remote service providers. The remote service providers can be selected using techniques such as reverse auctions, through which they compete for processing tasks. A great number of other features and arrangements are also detailed.

摘要： Imagery from two or more users' different smartphones is streamed to a cloud processor, enabling creation of 3D model information about a scene being imaged. From this model, arbitrary views and streams can be synthesized. In one arrangement, a user of such a system is at a sports arena, and her view of the sporting event is blocked when another spectator rises to his feet in front of her. Nonetheless, the imagery presented on her headworn display continues uninterrupted—the blocked imagery from that viewpoint being seamlessly re-created based on imagery contributed by other system users in the arena. A great variety of other features and arrangements are also detailed.

摘要： The detailed technology relates to optical sensors, and more particularly relates to characterizing local behaviors of a sensor, and using such characterization information in a sensor-based system. In a particular arrangement, output signals produced from each of plural sensing elements in a 2D optical sensor are checked to determine whether they tend to differ from output signals produced by one or more neighboring sensing elements—when combined across plural captured image frames. The results are stored in an associated memory, and can be consulted in determining how image data captured from the sensor should be used. The technology is particularly illustrated in the context of a watermark decoder for a cell phone camera. A variety of other features and arrangements are also detailed.
