A loop filtering method and device are provided. By optimizing the encoding method in the process of encoding and decoding loop filtering, the calculation complexity of loop filtering is reduced, the calculation speed is accelerated, and the encoding and decoding performance is improved. A loop filtering method includes determining multiple sets of filter coefficients for a loop filter, and encoding the multiple sets of filter coefficients by using a non-differential encoding method. Another loop filtering method includes determining a clip index parameter of a loop filter, and encoding the clip index parameter by using a non-exponential Golomb encoding method. Still another loop filtering method includes determining a loop filter clip parameter of a brightness component and a loop filter clip parameter of a chrominance component of an image frame, where the loop filter clip parameter of the brightness component and the loop filter clip parameter of the chrominance component are parameters selected from the same parameter list.

A video processing method, a video processing device, and a computer storage media. The method includes: obtaining a historical motion information candidate list; and encoding or decoding each first image block of a plurality of first image blocks according to the historical motion information candidate list. The historical motion information candidate list is used for encoding or decoding each first image block of the plurality of first image blocks in a first region of a current frame, and the historical motion information candidate list is obtained based on motion information of second image blocks. The second image blocks are encoded or decoded image blocks other than image blocks in the first region.

Systems, methods, and devices are provided herein for controlling one or more movable objects via a graphical user interface. A method for controlling a movable object may be provided. The method may comprise generating a motion path comprising at least one spatial point defined relative to one or more parameters of a target object; and determining one or more motion characteristics of the movable object for the at least one spatial point.

A control method for an assisted bicycle is provided, the assisted bicycle is equipped with an assistance assembly, and the assistance assembly is configured to output an assistance torque in response to power applied to the assisted bicycle from the outside. The method includes: obtaining power information applied to the assisted bicycle from the outside (110); determining a response speed of the assistance assembly based on the power information (120); and adjusting information related to the assistance torque output by the assistance assembly based on the response speed (130). The assistance assembly is controlled by adjusting a corresponding response speed according to the power information, so that the assistance assembly outputs the assistance torque at a more appropriate timing, thereby improving the intelligence level of the assistance and the user experience. The present application also provides an assistance assembly and an assisted bicycle.
