Abstract: Detecting fine-grained similarity in image includes determining a core area of a search image by generating an image salient map from a plurality of layers of the search image and determining a connected area based on the image salient map. Feature descriptors are generated from the core area of the search image. A plurality of capsule vectors are generated from different ones of a plurality of keypoints of the feature descriptors. Capsule vectors of the search image are compared with capsule vectors of each image of the dataset to generate a top-K matrix. Similarity scores for the top-K matrix are calculated. One or more image of the dataset having fine-grained similarity with the search image are selected based a bundled similarity score for each image of the dataset. The bundled similarity score is a summation of the similarity scores of the image.

Abstract: The utility model relates to a ring-shaped shrapnel structure of an H-MTD male connector, including a housing, a ring-shaped sheet, and a shrapnel. The housing is a stepped hollow structure. The ring-shaped sheet is connected to the front end of the housing. The shrapnel in an arch-shape protrudes and is arranged on the ring-shaped sheet. The structure uses a split design to separate the shrapnel from the housing, thereby reducing production difficulties and improving yields, while complementing the shielding effect of the connector.

Abstract: The utility model relates to a grounded shrapnel structure of an H-MTD male connector, including a housing of a hollow structure, a shrapnel in an arch shape, and a guide block. The front end of the housing is provided with an opening. The guide block is arranged horizontally. One end of the guide block is connected to one end of the opening. The other end of the guide block is connected to one end of the shrapnel. The structure uses only two surfaces at top and bottom that are grounded, thereby reducing the number of openings, improving the strength of a sidewall, and enhancing the shielding effect. In addition, the guide block can play the function of anti-scratching during assembly, which can effectively avoid the damage to the shrapnel during assembly and improve yield.

Abstract: A mode-locked fiber laser device is provided in the disclosure. The mode-locked fiber laser device includes a non-linear loop mirror, an optical splitter and a uni-directional loop. The uni-directional loop includes a polarization beam splitter and a Faraday rotator. The uni-directional loop is coupled to the non-linear loop mirror by the optical splitter to form a figure-8 optical path.

A second output laser pulse output by the optical splitter is propagated to the Faraday rotator to rotate the second output laser pulse 45 degrees, and the polarization beam splitter reflects the second output laser pulse to the outside of the mode-locked fiber laser device.
