Abstract: Enhanced vectorization of raster images is described. An image vectorization module converts a raster image with bitmapped data to a vector image with vector elements based on mathematical formulas. In some embodiments, spatially-localized control of a vectorization operation is provided to a user. First, the user can adjust an intensity of a denoising operation differently at different areas of the raster image. Second, the user can adjust an automated segmentation by causing one segment to be split into two segments along a zone marked with an indicator tool, such as a brush. Third, the user can adjust an automated segmentation by causing two segments to be merged into a combined segment. The computation of the vector elements is based on the adjusted segmentation. In other embodiments, semantic information gleaned from the raster image is incorporated into the vector image to facilitate manipulation, such as joint selection of multiple vector elements.

Abstract: Electromagnetically-induced cement concrete crack self-healing diisocyanate microcapsules include raw materials, in parts by weight, comprising 15-55 parts of petroleum resin, 5-10 parts of paraffin, 5-10 parts of polyethylene wax, 3-10 parts of magnetic iron powder and 20-67 parts of diisocyanate. The diisocyanate microcapsules use the diisocyanate as a core material, and the petroleum resin/paraffin/polyethylene wax/magnetic iron powder mixture as the shell of the capsule. When micro cracks occur in the concrete, the crack propagation can break partial of the microcapsule inside, the diisocyanate inside the microcapsules flows out and diffuses into the crack and is subjected to a solidifying reaction with water in the concrete, so that the crack is repaired in time; and for the microcapsules that are not broken by cracks, external electromagnetic field can be applied to melt the shell to release the diisocyanate inside, thereby diffusing into cracks and solidify with water to repair them.

Abstract: A gesture recognition method and related device. The method includes following steps. A current-frame image captured by a camera in a non-visible environment is obtained in response to detecting that an object enters a recognition range. The current-frame image is determined whether it contains a gesture by performing feature image detection on the current-frame image. If yes, feature points of the gesture in the current-frame image are obtained, and the gesture is traced according to the feature points to obtain gesture tracing data. And then the gesture tracing data is transmitted to a head mounted display device. The head mounted display device recognizes the gesture according to the positions of the feature points of the gesture to obtain a gesture recognition result; and perform a corresponding response action according to the gesture recognition result.

Abstract: The security of a QR code is substantially increased by removing an alignment pattern and/or a position detection pattern from a complete QR code to form an incomplete QR code. A complete QR code can be regenerated from the incomplete QR code with the proper imaging angle to the incomplete QR code. A malicious operator is unlikely to be able to obtain the proper imaging angle and is thereby unable to reconstruct a complete QR code from the incomplete QR code.

Abstract: Techniques for recommending sales leads from professional social networks using a prospect score (PS) are disclosed. A social networking system identifies a first and second group of members. The system accesses interactions between the first group and second group of members. The system calculates, for each member in the first group, a decision maker score (DMS), relationship score (RS), and social score (SS), the RS and SS values being based on the interactions. The system calculates, for each pair of members in the second group and first group, a PS based on the DMS, RS, and SS values. The system identifies connection paths between members in the second group and ranked members in the first group, the ranking being based on the PS values. The system recommends connection paths between members in the second group and members in the first group based on the identified connections and the PS values.

Abstract: Product records having attributes according to various schema are normalized such that the attributes thereof conform to a canonical schema. Attributes for large numbers of product records are normalized according to a map-reduce framework in which mappers are defined but no reducers. Rules are implemented by a rule engine that is instantiated one time per VM of the map-reduce framework. Likewise, each rule may be implemented by only one object instance per rule engine instance. Generation of rules by analysts may be facilitated by defining an attribute hierarchy. A rule defined for a parent attribute may be presented as a default rule for a child attribute and either accepted or revised. Attributes may be clusters and proposed rules generated. Proposed rules may then be accepted or rejected by an analyst.

Abstract: Methods for providing drawing assistance to a user sketching an image include geometrically correcting adjusting user strokes to improve their placement and appearance. In particular, one or more guidance maps indicate where the user “should” draw lines. As a user draws a stroke, the stroke is geometrically corrected by moving the stroke toward a portion of the guidance maps corresponding to the feature of the image the user is intending to draw based feature labels. To further improve the user drawn lines, parametric adjustments are optionally made to the geometrically-corrected stroke to emphasize “correctly” drawn lines and de-emphasize “incorrectly” drawn lines.

The valve body (A3/A4) includes a frame body (101/102), wherein two intersected supporters(2a, 2b/3a) are provided in the frame body (101/102) in a symmetrical manner, the supporters (2a, 2b/3a, 3b) intersect on a ridge-shaped column (2d/3d) and openings(2c1/3c2) are provided at intervals along the direction of the ridge-shaped column (2d/3d). The valve cores (200) are located above the openings (2c1/3c2) and the two valve bodies (A3, A4) are engaged and fixed; and one end of the valve core (200) is rotatably connected on the ridge-shaped column (2d/3d). Since the antiknock valve reduces the weight of the valve core (200), the antiknock capacity is improved, a closing speed is increases, and the antiknock valve is safer.
