A method, apparatus and device for synchronously playing audio are provided. The method includes: acquiring status information of a Bluetooth controller in the first audio playing device and Bluetooth time from the Bluetooth controller, and determining native Bluetooth time of the first audio playing device based on the status information and the Bluetooth time acquired from the Bluetooth controller; estimating, based on the native Bluetooth time of the first audio playing device and offset time of the native Bluetooth time of the first audio playing device relative to native Bluetooth time of a second audio playing device or native Bluetooth time of an audio providing device, absolute time of the second audio playing device or absolute time of the audio providing device; and playing an audio signal provided by the audio providing device synchronously with the second audio playing device based on the estimated absolute time.

Method, apparatus and device for synchronously playing audio

An image processing method is provided. The method includes obtaining at least two images, the at least two images being based on the same target object captured from different imaging angles, respectively; extracting, by using feature extraction networks included in an image processing model, target features of the at least two images, the feature extraction networks being configured to extract features of images corresponding to the different imaging angles, respectively; and determining, based on the target features, a classification result corresponding to the target object.

Image processing method and apparatus, computer-readable storage medium, and computer device

An image processing method performed by a terminal is provided. A molybdenum target image is obtained, and a plurality of candidate regions are extracted from the molybdenum target image. In the molybdenum target image, a target region is marked in the plurality of candidate regions by using a neural network model obtained by deep learning training, a probability that a lump comprised in the target region is a target lump being greater than a first threshold, a probability that the target lump is a malignant tumor being greater than a second threshold, and the neural network model being used for indicating a mapping relationship between a candidate region and a probability that a lump comprised in the candidate region is the target lump.

Image processing method and apparatus and neural network model training method

A method, apparatus and device for synchronously playing audio are provided. The method includes: acquiring status information of a Bluetooth controller in the first audio playing device, and determining native Bluetooth time of the first audio playing device based on the status information; estimating, based on the native Bluetooth time of the first audio playing device and offset data of the native Bluetooth time of the first audio playing device relative to native Bluetooth time of a second audio playing device or native Bluetooth time of an audio providing device, absolute time of the second audio playing device or absolute time of the audio providing device; and playing an audio signal provided by the audio providing device synchronously with the second audio playing device based on the estimated absolute time.

The present disclosure relates to a key generation method applied to a chip storing an internal key, which includes: acquiring () a first and a second random number; generating () an initial private key of the chip according to the first random number and the internal key, and generating an update private key of the chip according to the second random number and the internal key; generating () an initial public key corresponding to the initial private key according to the initial private key, and generating an update public key corresponding to the update private key according to the update private key; and sending () the initial public key, the update public key, and the second random number to a server that sends the second random number to the chip when receiving a private key update request of the chip, to trigger a private key update of the chip.

Key generation method and acquisition method, private key update method, chip, and server

A blower includes an air pump and a motor. The pump includes an impeller and a casing housing the impeller. The casing includes a casing inlet through which air is drawn in and a casing outlet through which the air is expelled by the impeller. The motor is arranged at the casing outlet and includes a stator and a rotor. The stator includes a stator core and a plurality of coils. The stator core includes a substantially ring-shaped yoke and a plurality of teeth extending inwards from the yoke. Each coil is wound around the yoke and is partially sandwiched between two adjacent teeth. The impeller is driven by the rotor.
