    Abstract: When a location of a wearable system changes, the wearable system can ensure that a gesture working region always remains in a field of view of the wearable system. Therefore, the wearable system can still collect and recognize a gesture image and implement gesture control. The solution provided in this application is as follows: The wearable system creates a gesture working region and a region of interest, where the region of interest is within a shooting area of a first camera, and the first camera is included in a wearable device; obtains a location parameter of the wearable system; adjusts the region of interest according to the location parameter, so that the region of interest covers the gesture working region; collects a gesture image within the gesture working region; recognizes the gesture image to obtain a gesture instruction; and performs a corresponding operation according to the gesture instruction.

    Abstract: A neural network model processing method includes obtaining a first low-bit neural network model through training, where the model includes a first operation layer and a second operation layer. Each operation layer includes at least one operation. Values/a value of a parameter and/or data used for the operation are/is represented by using N bits, and N is a positive integer less than 8. The neural network model processing method further includes compressing the model to obtain a second low-bit neural network model, where the compressed model includes a third operation layer. The third operation layer is equivalent to the first operation layer and the second operation layer, and an operation layer other than the third operation layer in the at least one operation layer is the same as an operation layer other than the first operation layer and the second operation layer in the at least two operation layers.

    Abstract: A target monitoring method, a camera, a controller, and a target monitoring system, where the system includes a first camera and a second camera. An overlapping area exists between fields of view of the first camera and the second camera. The method includes obtaining, location information of a to-be-tracked target in a first monitoring picture when the first camera is used as a current primary monitoring camera, determining, based on the location information of the target in the first monitoring picture, whether a location of the target in the first monitoring picture is in the overlapping area, where the overlapping area is an overlapping range between the fields of view of the first camera and the second camera, and switching, the current primary monitoring camera to the second camera when the location of the target in the first monitoring picture is in the overlapping area.

    Abstract: A method and an apparatus for converting a speech-to-text in a multiparty call. Receiving speech-to-text requests sent by at least two terminals, where the speech-to-text requests include a first identifier and a second identifier; allocating a session to the at least two terminals, so that in the speech-to-text requests sent by the at least two terminals, terminals that have a same first identifier or a same second identifier have a same session; receiving, by using a packet-switched domain, a voice stream whose sampling rate is greater than 8 KHz and that is sent by at least one terminal in one multiparty call, where the multiparty call corresponds to one session; converting the voice stream into a text; and sending the text to a terminal in the multiparty call.

    Abstract: An information processing method and apparatus in the field of mobile communications technologies is provided. In the method, a first terminal obtains, during a call with a second terminal by using voice information sent by the second terminal, to-be-obtained information and object information of an object to which the to-be-obtained information belongs. The first terminal determines at least one category to which the to-be-obtained information belongs and determines a group that is in any category of the at least one category and corresponding to the object to which the to-be-obtained information belongs. The first terminal searches information in the corresponding group in any category for target information associated with the object information and processes the target information with no manual searching being performed.
