Abstract: A first three-dimensional (3D) model of a target in a 3D space is acquired based on a first two-dimensional (2D) image including the target. A 3D morphing parameter is acquired. The first 3D model is transformed into a second 3D model based on the 3D morphing parameter. First 2D coordinates are acquired by mapping the first 3D model to a 2D space. Second 2D coordinates are acquired by mapping the second 3D model to the 2D space. A second 2D image including a morphed target is acquired by morphing the target in the first 2D image based on the first 2D coordinates and the second 2D coordinates.

Abstract: A portable blowing device includes a body and fans arranged in the body. Air channels are arranged in the body and extend in the length direction of the body to allow airflow to pass through. Wind shields are arranged in the air channels, and a periphery of the wind shield is closely connected with a side wall of the air channel so that a sub-air channel is formed between the wind shield and the side wall of the air channel. Air outlets are formed in the side wall for communicating with outside and the sub-air channel, and airflow generated by the fan can enter the sub-air channel and then exits the air outlets. Because of the reduced volume of the sub-air channel, the airflow is concentrated after entering the sub-air channel, and airflow exiting the air outlets is strengthened, so that the cooling effect and the user experience are improved.

Abstract: The present invention provides a balanced dipole unit and a broadband omnidirectional collinear array antenna formed by the balanced dipole unit. Balanced dipole unit circuits in the balanced dipole unit are symmetrically distributed on two sides of a circuit carrier, and a feeder and a ground wire in the balanced dipole unit are also symmetrically distributed, so that the balanced dipole unit has a completely symmetrical structure. A principle of the symmetrical structure is the same as a differential design principle and a self-balancing principle in the circuit design, thereby reducing current coupling between the balanced dipole units and eliminating the need of using an additional choke circuit when a broadband omnidirectional collinear array antenna is formed by the balanced dipole unit.
