Abstract: A photographing method is provided. In the method, based on a video call between terminals at two places, each terminal previews, in a preset template, real-time preview video streams of the two parties. The two parties may separately adjust a picture of a local preview stream, and obtain a respective high-definition image through snapping when a preview group photo image is satisfying. Through file backhaul, one terminal can generate a high-resolution remote group photo based on snapped high-definition images of the terminals, a picture adjustment parameter during snapping, and the preset template.

Abstract: A channel estimation apparatus and method are provided to ensure that a channel estimation value can correctly reflect a transmission channel status, so that an orthogonal frequency division multiplexing (OFDM)-based wireless system can correctly transmit an aggregate long frame according to the channel estimation value. The channel estimation apparatus determines a first channel estimation value, receives a first symbol group of a long frame according to the first channel estimation value, and determines a second channel estimation value according to the first symbol group, and if a difference between the first channel estimation value and the second channel estimation value is less than or equal to a first threshold, determines a third channel estimation value according to the first channel estimation value and the second channel estimation value.

Abstract: A method, an apparatus, and a device are provided for information transmission. In the method, the apparatus determines an initial OFDM symbol in OFDM symbols used to transmit load information. The apparatus determines, starting from the initial OFDM symbol, a phase deviation difference between two adjacent OFDM symbols according to first information to be transmitted. The apparatus performs phase deviation on at least one of the OFDM symbols according to the phase deviation difference. The apparatus then sends the OFDM symbols obtained after the phase deviation to a receiving end.

Abstract: An apparatus for implementing digital baseband predistortion includes a transmission channel including a digital-to-analog converter, a modulator, an amplifier and a power amplifier, and further includes a feedback channel analog part including a diode detector, a filter and an analog-to-digital converter, and a feedback channel digital part including a predistorter, a mode obtaining unit, a predistortion coefficient generator and a feedback correcting unit. The diode detector is configured to obtain an envelope of an output signal of the power amplifier. Embodiments of the present invention further provide a method for implementing digital baseband predistortion by applying the foregoing single-chip. Due to a simple structure of the diode detector, not only the number of radio frequency devices on the feedback channel is reduced, implementation complexity of hardware is lowered, power consumption is reduced, but also a feedback channel analog part may be integrated onto the single-chip.

Abstract: The disclosure relates to technology for object detection in which a vision system receives training datasets including a set of two-dimensional (2D) images of the object from multiple views. A set of 3D models is reconstructed from the set of 2D images based on salient points of the object selected during reconstruction to generate one or more salient 3D models of the object that is an aggregation of the salient points of the object in the set of 3D models. A set of training 2D-3D correspondence data are generated between the set of 2D images in a first training dataset of the training datasets and the salient 3D model of the object generated using the first training dataset. A deep neural network is trained using the set of training 2D-3D correspondence data generated using the first training dataset for object detection and segmentation.
