A passive hummingbird water feeder and a feeding method thereof. By setting up an air cavity pipe, a delivery pipe, and a water storage bladder, and based on the siphon principle, water is introduced from the container into the water storage bladder without power with water level maintained, allowing water filling directly from above the container. The design simulates the foraging habits of hummingbirds, and enables photographing of flowers and birds.

The present invention belongs to the field of shooting, and provides a shooting method and camera based on multi-camera linkage. The first camera is a fixed wide-angle camera, and tracks and acquires the position of the shooting target in real time. The image processing technology is used to analyze the composition quality and determines an optimal second camera shooting position coordinate. The control module sends a rotation instruction to enable the second camera to track the shooting target in real time, so as to ensure that the shooting target keeps the center position in the close-up image. When it is analyzed that the shooting target occupies the proper proportion and angle in the picture, the second camera is started to track and shoot, and during shooting, the second camera is zoomed and rotated according to the position of the shooting target, so that better image shooting is achieved.

The present invention discloses a bird photographing method, a readable storage medium, an electronic device and a bird feeder, wherein: a bird approaching and staying on the feeding tray is detected, and a photographing mechanism photographs the bird and judges the pre-composition; if the pre-composition is determined to conform to composition rules, the bird is determined as a subject, and the lens focal length is adjusted according to the position information, and video materials are obtained by continuously shooting from the first side to the second side of the subject; if the pre-composition is determined not to conform to composition rules, the photographing mechanism switches to standby or off mode. The present invention is simple in structure and intelligent, and ensures the subject properly positioned in the images, and the automatic, clear and complete photographing of birds facilitate the observation and recording of bird lovers and scientific researchers.

According to an embodiment, a candidate node having a potential association relationship with a target node, an association node having an association relationship with the target node, and a grouping identifier of the association node are obtained. A relevance degree between the association node and the target node and a relevance degree between the candidate node and the target node within each grouping identifier are obtained. Based on the relevance degrees, the association node and the candidate node in each grouping identifier are combined for outputting.

Method, apparatus, and computer-readable storage medium for grouping social network nodes

A method, system and computer-readable storage medium for grouping users of an online social network application are provided. The method includes: acquiring friend relation data of a first user, the friend relation data comprising one or more friend nodes; determining a weight of each of the friend nodes based on the friend relation data acquired; forming a first friend circle with a first friend node having a greatest weight among the friend nodes; traversing the friend nodes to find an optimum friend of the first friend circle; adding the optimum friend into the first friend circle; and repeating the traversing and adding until all optimum friends of the first friend circle are added into the first friend circle. The method determines the weight of each friend node based on the friend relation data and performs grouping by the weights, which is able to conduct as mart grouping with high speed, low throughput, and high efficiency.
