  • Patent number: 10839006
    Abstract: An approach for performing mobile visual search uses deep variant coding of images to reduce the amount of data transmitted from mobile devices to a search server and to provide more efficient indexing and searching on the search server. The amount of data used to represent an image varies depending upon the content of the image and is less than conventional fixed bit length hashing approaches. Denser regions of a feature space are represented by more encoding bits and sparser regions of the feature space are represented by fewer encoding bits, so that the overall number of encoding bits for an image feature is reduced. The approach generally involves determining a set of hash functions that provide deep hashing with more evenly-distributed hash buckets. One or more additional hash functions may be selectively generated for particular hash buckets that contain more than a specified number of images.

  • Publication number: 20200353759
    Abstract: A method of manufacturing a thermal print head structure includes the following steps. A glaze layer, a heating resistor layer, an electrode layer and a photoresist layer are sequentially coated on a substrate, in which the photoresist layer has an arc ridge portion in accordance with the formation of the glaze layer. The arc ridge portion of the photoresist layer is partially removed such that a sunken portion is formed on the arc ridge portion. The photoresist layer is fully thinned to remove a bottom of the sunken portion, so that a local position of the electrode layer is revealed. The local position of the electrode layer is etched so that the heating resistor layer is partially revealed outwardly. The photoresist layer is removed from the electrode layer. A protective layer is formed on the electrode layer, the heating resistor layer, and the substrate.

    Abstract: A method of determining and displaying movement of an object in an environment using a moving camera includes identifying later environment features located in the environment in a later image, earlier environment features located in the environment in an earlier image, and earlier object features located on the object in the earlier image. The method further includes estimating object features in the later image using the earlier object features and a determined camera movement. The method further includes locating, in the later image, matched object features that are actual object features in the later image at a same location as the estimated object features. The method further includes determining that the object has moved between the earlier image and the later image if a number of matched object features does not exceed a threshold.
