Abstract: This application discloses an image retrieval method and apparatus, a system, a server, and a storage medium. The method includes: obtaining a first hash value of a to-be-retrieved reference image; splitting the first hash value into a preset quantity of first hash value segments, wherein a first hash value segment of the first hash value segments has a unique sequence position corresponding to a position of the first hash value segment in the first hash value; locating a target hash table according to the sequence position of the first hash value segment, wherein the target hash table is used for storing hash value segments that are at the sequence position of the first hash value segment in hash values of images; retrieving, from the hash value segments of the target hash table, a second hash value segment that is the same as the first hash value segment; and retrieving, from candidate images to which the second hash value segment belongs, a target image similar to the reference image.

Abstract: Provided are a wireless earphone and a method for controlling a wireless earphone. The wireless earphone includes a charging box and an earpiece placed in the charging box. A charging box open/closed-state sensor, an earpiece attitude sensor and a magnetic-field control circuit are disposed in the charging box. The charging box open/close-state sensor is configured to detect an open state of the charging box or a closed state of the charging box. The earpiece attitude sensor is configured to detect an orientation attitude of the earpiece in the charging box. The magnetic-field control circuit controls, according to results detected by the charging box open/closed-state sensor and the earpiece attitude sensor, whether the earpiece is suspended from the charging box.

Abstract: A similar picture identification method is described. According to the method, processing circuitry of a device obtains n first local regions of a first picture, the n first local regions being a first set of regions that is affine invariant, and obtains m second local regions of a second picture, the m second local regions being a second set of regions that is affine invariant. The processing circuitry obtains n first characteristic values respectively corresponding to the n first local regions, and obtains m second characteristic values respectively corresponding to the m second local regions. The processing circuitry further determines, according to a comparison result of the n first characteristic values and the m second characteristic values, whether the first picture is similar to the second picture, where n and m are positive integers.

Abstract: An image information recognition processing method, device and a computer storage medium are provided. A first reference image and an image to be detected are acquired. Nth interception or cutting processing on the image to be detected is performed in a specified direction to obtain an Nth sub-image according to a first preset rule. First attribute values and/or second attribute values of the first reference image and the Nth sub-image are acquired respectively, the first attribute values being configured to represent color distribution information of the images and the second attribute values being configured to represent fingerprint information of the images. When the first attribute value and/or second attribute value of the Nth sub-image and the corresponding attribute value(s) of the first reference image meet a predetermined condition, it is recognized that the image to be detected to which the Nth sub-image belongs is matched with the first reference image.
