Abstract: The present disclosure belongs to the field of photoacoustic signal detection, and specifically relates to a quantum-enhanced all-optical photoacoustic signal detection device and method. The problem of low sensitivity of photoacoustic signals based on interference measurement is solved, and high-sensitivity detection of photoacoustic signals generated by living organisms including human bodies can be achieved. A degenerate optical parametric oscillator based on a first-type phase matching crystals is used for preparing a vacuum squeezed state light field, a coherent control technology is used for locking the squeezed angle to obtain the quadrature phase vacuum squeezed state, the prepared quadrature phase vacuum squeezed state light field is injected into the vacuum channel of a Michelson interferometer, and a balanced homodyne detection mode is used for achieving detection of the quantum-enhanced photoacoustic signals.

Abstract: According to various embodiments, the present invention provides a product indexing method including receiving product data of a product, the product data comprising at least an image, such that the image includes a product image of the product and a context image which provides the context that the product may be in, such that the context image includes at least one non-product image. Product indexing method further includes identifying the product image, identifying the context image from the image, verifying the product in the product image based on the context image, extracting the product image and indexing the product image. According to various embodiment, the present invention provides a product indexing system for the product indexing system.

Abstract: Method, apparatus, computer program product and computer readable medium are disclosed for privacy protection. A method may comprise: receiving encrypted data from a top participating node of a participant chain, which comprises a plurality of participating nodes; and decrypting the encrypted data, wherein the encrypted data comprise a plurality of encrypted sensory data obtained respectively by said plurality of participating nodes.

Abstract: Present example embodiments relate generally to systems, devices, and methods for managing video content. The method may include receiving an input video having one or more video frames. The method may also include selecting a video frame from the input video that displays a target product and/or other feature. The method may also include generating an alternative representation of the target product and/or other feature displayed in the selected video frame. The method may also include searching a content database for media content that is likely to pertain to the target product and/or other feature displayed in the selected video frame. The searching of the content database may be performed using the alternative representation of the target product and/or other feature. The method may also include associating a most likely matching media content found, in the searching, to the selected video frame.

Abstract: A clothing search system provides a clothing search to users using a component-based image search. Retailer catalogs are analyzed to determine clothing components within clothing images. Features associated with the components are determined. When a user requests a clothing search, the clothing search system selects clothing based on the components and features requested by the user. The user may also provide an image to the clothing search system. The clothing search system determines components and features of the image and identifies clothing with matching components.

Abstract: Media content relevant to an input video is identified by analyzing video frames in the input video to detect if any of the video frames contain a target product. One or more video frames found to be containing a detected target product is selected and a product thumbnail is generated for each of selected the video frames. At least one product thumbnails is selected and a video product visual index is generated for each of the selected product thumbnail. Relevant media content is then identified for each of the product thumbnails by comparing the video product visual index of each of the selected product thumbnail with a plurality of media content visual index in a media content database. Each media content visual index is associated with one media content in the media content product database.

Abstract: An approach is provided for discovering social ties among users based on cloaked trajectories. In a method, cloaked regions of a first trajectory of a first user and cloaked regions of a second trajectory of a second user are transformed to corresponding semantic regions, respectively, wherein a semantic region is expressed with a semantic meaning of a corresponding cloaked region. The transformed semantic regions are mapped into nodes of a hierarchical semantic tree, wherein each node of the hierarchical semantic tree corresponds to a semantic region. According to relationships between nodes mapped to semantic regions of the first trajectory and node mapped to the semantic regions of the second trajectory, social ties among the first user and the second user can be inferred.
