  • Patent number: 9594983
    Abstract: A sequence of images depicting an object is captured, e.g., by a camera at a point-of-sale terminal in a retail store. The object is identified, such as by a barcode or watermark that is detected from one or more of the images. Once the object's identity is known, such information is used in training a classifier (e.g., a machine learning system) to recognize the object from others of the captured images, including images that may be degraded by blur, inferior lighting, etc. In another arrangement, such degraded images are processed to identify feature points useful in fingerprint-based identification of the object. Feature points extracted from such degraded imagery aid in fingerprint-based recognition of objects under real life circumstances, as contrasted with feature points extracted from pristine imagery (e.g., digital files containing label artwork for such objects).

  • Patent number: 9557162
    Abstract: 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. The image processing tasks applied to the scene can be selected from among various alternatives by reference to resource costs, resource constraints, other stimulus information (e.g., audio), task substitutability, etc. The phone can apply 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 some arrangements, data may be referred to the cloud for analysis, or for gleaning. Cognition, and identification of appropriate device response(s), can be aided by collateral information, such as context. A great number of other features and arrangements are also detailed.

  • Publication number: 20160322082
    Abstract: Arrangements involving portable devices (e.g., smartphones and tablet computers) are disclosed. One arrangement enables a content creator to select software with which that creator's content should be rendered—assuring continuity between artistic intention and delivery. Another utilizes a device camera to identify nearby subjects, and take actions based thereon. Others rely on near field chip (RFID) identification of objects, or on identification of audio streams (e.g., music, voice). Some technologies concern improvements to the user interfaces associated with such devices. Others involve use of these devices in connection with shopping, text entry, sign language interpretation, and vision-based discovery. Still other improvements are architectural in nature, e.g., relating to evidence-based state machines, and blackboard systems. Yet other technologies concern use of linked data in portable devices—some of which exploit GPU capabilities. Still other technologies concern computational photography.

  • Patent number: 9445763
    Abstract: Audio sounds are captured from a subject's body, e.g., using a smartphone or a worn array of microphones. Plural features are derived from the captured audio, and serve as fingerprint information. One such feature may be a time interval over which a threshold part of spectral energy in the audio is expressed. Another may be a frequency bandwidth within which a second threshold part of the spectral energy is expressed. Such fingerprint information is provided to a knowledge base that contains reference fingerprint data and associated metadata. The knowledge base matches the fingerprint with reference fingerprint data, and provides associated metadata in return—which can comprise diagnostic information related to the captured sounds. In some arrangements, an audio signal or pressure waveform stimulates the body at one location, and is sensed at another, to discern information about the intervening transmission medium. A great variety of other features and arrangements are also detailed.

  • Publication number: 20160267620
    Abstract: In one aspect, assembly of multi-part food packaging is checked by reference to payloads of steganographically-encoded digital watermarks printed across plural components of the packaging. Marking all surfaces of the packaging components allows arbitrary orientation of feed stock in assembly equipment, and wide latitude in placement of inspection cameras along the packaging line. In another aspect, a scanner at a retail checkout station is alert to any gap detected in steganographic encoding on retail product packaging and, if found, alerts an operator to possible presence of an adhesive label with a misleading barcode. A great variety of others features and arrangements are also detailed.

  • Patent number: 9401541
    Abstract: In accordance with one aspect of the present technology, information about multipath in an area is gained by occasionally switching the directivity of one or more of the involved antennas (transmitting or receiving). Based on resulting changes in signal strength, information about the multipath effects can be discerned, and corresponding action may thereafter be taken. Another aspect of the technology involves localizing sources of multipath by reference to multiple receiving stations, such as cellular receivers at cell towers in adjoining cells of a wireless network.

  • Publication number: 20160063821
    Abstract: In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed views—further minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modeled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. Logos may be identified and used—or ignored—in product identification. A great variety of other features and arrangements are also detailed.

  • Publication number: 20160005278
    Abstract: A variety of haptic improvements useful in mobile devices are detailed. In one, a smartphone captures image data from a physical object, and discerns an object identifier from the imagery (e.g., using watermark, barcode, or fingerprint techniques). This identifier is sent to a remote data structure, which returns data defining a distinct haptic signature associated with that object. This smartphone then renders this haptic signal to the user. (Related embodiments identify the object using other means, such as location, or NFC chip.) In another arrangement, haptic feedback signals social network information about a product or place (e.g., the user's social network friends “Like” a particular brand of beverage). In yet another arrangement, the experience of watching a movie on a television screen is augmented by tactile effects issued by a tablet computer on the viewer's lap.

  • Patent number: 9179200
    Abstract: Metadata determines treatment of content by automated systems, including “user generated content” web sites. The metadata may be conveyed with the content or may be determined by other techniques, including systems based on digital watermarking or content fingerprinting. In some arrangements, treatment depends on the temporal length of a content excerpt that matches a pre-existing work. In others, treatment depends on popularity—either of the content, or a pre-existing work from which it was derived. A great variety of other factors and contexts can also be considered. Automated tools to preliminarily identify possible “fair use” can be realized; further determination may be made by human evaluators (including crowd-source approaches).
