  • Publication number: 20240116612
    Abstract: A pyram-shaped deep-sea pressure-resistance shell and a design method therefor. The shell comprises a conical shell, an annular combined shell, a cylindrical shell, a flange bolt, and a perforated thick plate; a bottom end of the conical shell is connected with a top end of the annular combined shell, the conical shell being in communication with an interior part of the annular combined shell; the perforated thick plate blocks the bottom end of the annular combined shell, the perforated thick plate and the annular combined shell being connected by means of multiple flange bolts; the cylindrical shell is disposed inside the annular combined shell, a lower end of the cylindrical shell being inserted in a gap between the annular combined shell and the perforated thick plate.

  • Patent number: 10860839
    Abstract: The present disclosure provides a method and apparatus for generating training data for human face recognition, a device and a computer storage medium, wherein the method comprises: inputting accessory-not-worn face images into a generative network, to obtain accessory-worn face images; using the accessory-worn face images as second training data for building the human face recognition model; wherein the generative network is a generative network in a generative adversarial network obtained by pre-training with first training data, the first training data including the accessory-not-worn face images and accessory-worn face images corresponding to a same user identifier. In the present disclosure, the accessory-worn face images obtained in a data augmentation manner greatly expand the amount of training data for building the human face recognition model, and thereby improve the recognition accuracy of the accessory-worn face images.

  • Patent number: 10719693
    Abstract: Embodiments of the present disclosure disclose a method and apparatus for outputting information. The method includes: acquiring a first image and a second image, the first image including a first face image region, and the second image including a second face image region; generating an image matrix of the first image and an image matrix of the second image; inputting respectively the image matrix of the first image and the image matrix of the second image into a pre-trained convolutional neural network to obtain a characteristic vector of the first image and a characteristic vector of the second image; calculating a distance between the characteristic vector of the first image and the characteristic vector of the second image; and outputting, based on the calculated distance, information of an object relationship between an object the first face image region belongs and an object the second face image region belongs.
